Vermouth, a Black Organization member who specializes in disguise and reconnaissance, flew from America to Japan some time after Sherry's escape from the Organization. Her objective was to track down and eliminate the 'traitor', and for that purpose she assumed the identity of doctor Tomoaki Araide. FBI agents Jodie Starling, Shuichi Akai, and James Black followed her to Japan on a secret mission to arrest her and learn more about the Black Organization in order to destroy it. Meanwhile, Conan and Haibara get caught up in Vermouth and the FBI's silent battle as Conan attempts to uncover the identities, motives, and allegiances of the strange people who have appeared around him.
Conan and Haibara go to intercept an assassination by Pisco. They fail to stop the assassination, but Conan discovers that Pisco must be one of the suspects with a purple handkerchief. One of the suspects is Chris Vineyard, 29 year old American actress. Megure holds all the participants with a purple handkerchief for questioning, including Chris Vineyard. To help Pisco out, Chris gives Pisco her purple handkerchief. When Pisco returns to the room where Haibara is and confronts Conan, Conan suspects Pisco had help from someone else at the party, although he doesn’t know which person it is.
At the end of this case, Gin and Vodka pick up Chris Vineyard, and reveal that her codename is Vermouth. She flew over from America to help Pisco. Rather than fly back, Vermouth says she wants to stay in Japan for a while because she had “something unsettling in her mind”; probably Conan and Haibara whom she recognized as Shinichi and Shiho.
Vermouth takes the place of Tomoaki Araide, the nurse at Teitan elementary and high school sometime after this. Soon afterwards, the FBI who had followed her from America raid Araide’s office and see the pictures of Conan, Ran, and Sherry that Vermouth had tacked to her dartboard.
The exact time Vermouth replaced Araide was left unclear. At the earliest, Ran reported that Araide had already accepted the position of play director at the beginning of "Mistaken Detectives". It is also plausible Vermouth disguised as Araide prior to Desperate Revival. Jodie's reference pictures hidden behind her mirror include a photograph of Dr. Araide taken at the school play indicating that Araide was under investigation then. There are also copies of Vermouth's photographs, meaning Dr. Araide's office had been raided by the FBI and thus Vermouth was in disguise at the time. The mixed layering of the photos suggests they were acquired at around the same time. At the very latest, Vermouth was already in disguise when Jodie's introduction occured because Jodie had already raided Araide's office and seen the pictures tacked to Vermouth's dartboard.
It is revealed that Araide will substitute for the school drama’s Black Knight role who will kiss Ran.
In Desperate Revival, Shinichi takes a temporary antidote, participates in a school play as the Black Knight, and solves a murder case that occurs during the performance. Dr. Araide was supposed to be the knight, but traded places with Shinichi who already knew the script. Dr. Araide sees Shinichi in his teenager grown form.
Jodie Starling, an FBI agent who is hunting Vermouth, makes her first appearance during a murder case at an arcade. At the end of the case, she tells a fellow agent that she found “rotten apple”, the FBI’s codename for Vermouth. She also calls Conan “Cool Guy”, the caption Vermouth wrote on Conan’s pictures meaning the FBI has already raided Araide’s office and seen them.
At a bar after completing an assassination, Gin and Vodka are approached by Vermouth in a barman's disguise. Vodka is fooled, but Gin knows her instantly and is unamused. He asks if she has found what she was looking for in Japan yet, but Vermouth plays coy about her goal and flirts with Gin instead.
Conan, Haibara, Dr. Araide (Vermouth), Jodie, and Shuichi Akai are on a bus which gets hijacked. Haibara reveals she sensed Vermouth at the party in Reunion with the Black Organization, but doesn’t tell Conan Vermouth’s codename. Haibara senses Vermouth’s presence on the bus. Dr. Araide jumps into protect Conan when one of the hijackers threatens to kill him. Vermouth steals the records of Kogoro Mouri's cases from the police department after the bus jack.
Dr. Araide comes to a Japanese restaurant for an unknown reason. Akai is there too to investigate Vermouth. Conan, not suspecting Dr. Araide at this point, ruffles Araide’s hair, takes his glasses off, and uses his voice changer so the Araide’s silhouette looks like Wataru Takagi’s. Vermouth realizes the ploy and cooperates.
Takagi tells Conan that Kogoro Mouri’s case records were stolen from police headquarters by someone after the bus jack then later returned. This is later revealed to be Vermouth who needed to get information on Araide’s case so she could testify at the trial properly. She also intended to lure the FBI out by getting them watch Mouri Kogoro’s office.
This is the first time the readers see Vermouth’s posterboard, although chronologically this scene occurred prior to this point in time sometime between Reunion with the Black Corps and the Battle Game Trap. She writes a somewhat teasing letter to Gin. She has pictures of Shiho with and X drawn though it, Conan with the caption “Cool Guy”, and Ran with the caption “Angel”.
Conan tells Agasa the case files stolen by Vermouth earlier were also returned. Conan is unsure of why.
Jodie has pictures of the pictures that Vermouth had with the exception of Shiho’s. The office had been broken into by FBI prior to this point in time. Jodie also added Dr. Araide, Shinichi in the prince outfit, and pictures of Teitan High School and Mouri Detective Agency.
One year before the current timeline, Shinichi, Ran, and Yukiko visit New York city to see the Broadway production: "Golden Apple" after getting tickets from Sharon Vineyard, Vermouth's current persona. Sharon greets Yukiko disguised as police inspector Radish Redwood in order to keep Yukiko from getting a traffic ticket. Sharon talks with Yukiko a little about her troubled past, deaths in the family, Chris Vineyard, and learning disguise from Toichi Kuroba. Sharon, Yukiko, Shinichi, and Ran go backstage to meet with the actresses. Sharon gives Ran a handkerchief after she scrapes her arm knocking one of the actresses out of the way of a falling suit of armor. Sharon leaves after that saying she has something to take care of and she has a bad feeling about that night.
After leaving Yukiko, Shinichi, and Ran at the theater, Sharon Vineyard disguises as a wanted silver haired male serial killer to lure out Shuichi Akai and kill him. Vermouth underestimates Akai and he shoots her in the side. Vermouth escapes, but Akai continues to look for her. Vermouth hides in an empty building; however, she is discovered by Shinichi who went to retrieve the handkerchief Sharon gave to Ran. Ran goes to look for Shinichi after being told by Akai to leave because the serial killer was around. On the external stairwell several floors up, Ran comes face to face with Vermouth disguised as the silver haired serial killer with Shinichi in hot pursuit from above. Vermouth prepares to kill Ran with a silenced handgun, but the railing she is leaning on breaks. Ran instinctively grabs Vermouth's arm to stop her from falling and with Shinichi's help Vermouth launches herself back up onto the stairwell. She demands to know why Shinichi and Ran saved her, and Shinichi answers:
Ran collapses and Vermouth levels her gun at Shinichi, but Shinichi warns her off as it is unsilenced and she will be caught if she fires. Shinichi carries Ran away, leaving Vermouth to contemplate the conversation.
Is a reason necessary? I don't know why you would kill someone, but as for helping someone, a logical mind isn't needed, right?—Shinichi explaining to Vermouth disguised as the silver haired serial killer why he saved her, Manga Volume 35, File 4, pg 12
Vermouth clears the stairwell and building of blood and fingerprints and later the body of the real silver haired man is found when the police arrive. The death was ruled a suicide but later Shinichi hypothesizes Vermouth sacrificed the man to cover her trail. Sharon and Yukiko talk the next day by phone while Sharon clutches her side in the precise place where the serial killer was shot. She asks Yukiko to tell Ran there was an angel for her. After this, Vermouth refers to Ran as "angel" and Shinichi/Conan as "cool guy".
Ran talks to Shinichi on the phone about the New York case, Sharon’s handkerchief, and the mysterious serial killer. Shinichi reveals he looked into the case and discovered the serial killer’s blood and fingerprints had all been wiped before the police arrived which makes no sense for someone committing suicide. He asked the local police to look into it, but nothing turned up.
Ran is treated at Araide clinic by “Dr. Araide” after collapsing. Vermouth still needs to give testimony at court on the Araide family murder case which was part of the reason she stole the records of Mouri’s case. Vermouth is having some difficulty keeping in character; one of her patients says Dr. Araide has been acting like a stranger. Also, Araide claims to have sent his grandmother and housekeeper Hikaru ahead to Aomori, which is strange because it was established in 235-236 that Araide didn't trust them (especially the maid) to take care of themselves.
One of Black Organization target Itakura’s diary entries reveals he had been corresponding with Vermouth about a year ago. The woman demanded Itakura complete a program he had stopped developing. Itakura questioned the woman angrily about “Who the hell she thinks she is?!” and she replied in English, "We can be both God and Devil since we are trying to raise the dead against the stream of time".
Much later on the Bell Tree Express it is confirmed that Vermouth was the woman on the other end of the line. Itakura was well known for doing visual effects for movies and had met Sharon Vineyard on sets. She disguised her voice and ordered a program from him. For uncertain reasons, he and Sharon later had a nasty falling out on a set and frequently argued after that.
Haibara is sick. Conan lies to Agasa about making a call to Dr. Araide saying he tied up with the court case. Later, a case occurs when Agasa and Conan take Haibara out to another clinic. Haibara gets worse during the case and Agasa calls Dr. Araide. Araide is surprised when Agasa mentions Conan’s supposed call, saying he has been in the office all day, but a call came in when he was in the bathroom. Conan lied about making the call, because he really didn't want Araide near Haibara. Agasa asks Araide to pick Haibara up because they are stuck in a case. Meanwhile Akai, who has Araide’s office bugged, contacts Jodie to intercept to keep Vermouth from being alone with Haibara.
Araide, Agasa, and Jodie go to Agasa’s house. Araide treats her while there and Jodie helps out. While they are there, Vermouth bugs Agasa’a house.
At the end of this case, Vermouth is seen later in her office with the dart board pouring herself a drink. She announces to herself that she has found Sherry and is coming for her. She takes Sherry's picture off the dartboard and burns it. Similar scenes with Vermouth in the office occurred much earlier chronologically than when shown in the chapters, but it unclear when this scene took place in the timeline.
Vermouth is listening in on bugs that have been planted in the house to Conan and Agasa’s discussion about an architect friend of Professor Miyano’s. Conan knows about the bugs, but doesn’t remove them because he isn’t sure of the consequences might be. Later, Vermouth contacts Calvados and tells him to finish off someone.
Vermouth sends a signed off-season Halloween party invitation to Kogoro Mouri and to Conan addressed for Shinichi Kudo challenging them to solve a murder on the ship. Conan asks Haibara who is still sick about the name Vermouth, and learns from her reaction that it is the codename of one of the Black Organization members.
Agasa’s house is still bugged and Conan takes advantage of that to manipulate Vermouth into believing he is going to go to the party. Conan knows at this time Vermouth wants to avoid catching him up in her plan to capture Sherry because of the events at New York in the Golden Apple case.
Gin has been ordered by the boss to look into Vermouth’s movements related to the Halloween party and tells Vodka to board the ship and investigate. He has no idea what Vermouth is doing but tells Vodka to kill her if she does anything weird even if she is the boss’s favorite.
Heiji Hattori disguised as Shinichi Kudo under a layer of bandages boards the ghost ship. Vodka in costume boards as well. A murder takes place on the ghost ship as Vermouth said. At Agasa's house, Conan has been disguised as Haibara by Yukiko Kudo, and he has locked the real Haibara in the basement to keep her safe. Conan doesn't know Heiji broke the lock. Dr. Araide calls Agasa’s, initiating her plan believing Haibara should now be alone, and the disguised Conan answers. Dr. Araide says he is coming to pick up Haibara because her cold doesn't seem to be getting any better. Conan agrees.
Jodie, trying to protect Haibara after hearing the exchange on the phone through the bugs, picks up Conan disguised as Haibara before Dr. Araide can get there. Dr. Araide sees Jodie pulling away and he follows. Conan notices Dr. Araide is following. Unknown to all parties involved, Ran is hiding in Jodie's trunk.
During the car ride, Conan tells Jodie that he will trust her if she can force Dr Araide to reveal she is Vermouth. Jodie agrees. Araide and Jodie arrive at the wharf. Dr. Araide stays in character and Jodie sets a trap for him using the story about the murder at Dr. Araide's house. Vermouth doesn't know the police and the murderer put together a false investigation to protect the maid Hikaru as she was the one who flipped the switch that caused the electrocution. Vermouth falls for the trap, Jodie tells the truth and Vermouth takes off the Araide mask.
The chapter opens with a flashback to twenty years ago when Vermouth killed Jodie's father who was in the FBI investigating her. After Vermouth killed Jodie's father she inadvertently handled Jodie’s father’s glasses barehanded which had fallen off of him and got her fingerprints on them. Unexpectedly, little Jodie came in and saw Vermouth holding the glasses. When Vermouth left after setting the house on fire, she didn't anticipate that Jodie left to get juice, taking her father’s glasses with her and thus preserving her fingerprint. After she discovered Jodie's corpse was not found in the house, Vermouth looked for the girl desperately in order to rectify her mistake, but Jodie had since been put into witness protection.
The murder on the ghost ship was solved by Hattori Heiji and the murderer reveals someone named Vermouth forced him to commit the crime. The man who had resentment for the victim posted in a murder forum that he wanted to kill him. Someone named Vermouth had replied back and asked if he would be willing to kill the victim if Vermouth provided the technique and the tools to do so. The murderer refused, but then Vermouth mailed him pictures of him and his family, tapes of intercepted phone calls, and detailed notes of the his families' daily actions. The parcel came with a threat that if the man didn't carry out the murder or reported Vermouth to the police, he and his family would die. Vodka overhears this and presumably reports it to Gin who reports to the boss.
It is also revealed that Vermouth visited Araide clinic with only a cold intending to kill Araide and impersonate him. The FBI faked Araide and his family’s deaths by having doubles drive his car off the road in front of Vermouth’s car. Vermouth took advantage of the accident to replace Araide.
Jodie proceeds to ask Vermouth some questions which Vermouth doesn't answer. Jodie asks if Haibara and the woman in the Sherry's picture are the same person. She asks about Ran and Conan's pictures. Jodie also asks why Vermouth protected Conan during the bus jack case. She reveals that Sharon and Chris Vineyard are the same person and asks why Vermouth does not appear to age.
Jodie calls out for her fellow FBI agents to arrest Vermouth, but Vermouth had come to this spot ahead of time disguised as Jodie and had sent all the FBI agents waiting out in advance away. Instead Calvados, a sniper infatuated with Vermouth, is waiting instead and shoots Jodie. Vermouth prepares to kill Jodie when Conan kicks her gun away with a soccer ball and removes his Haibara disguise. The real Haibara also arrives after tracking Conan with the tracing glasses.
Shuichi Akai sneaks up Calvados and disables him. Jodie moves out of the sniper's range and shoots Vermouth in the shoulder. Akai appears and surprises Vermouth. He proceeds to insult her by calling her a 'rotten apple' provoking Vermouth to shoot him, but Akai fires with his gun first and wounds Vermouth badly. Akai shows Jodie that the shotgun scared Vermouth's face, revealing that she isn't wearing a mask to hide her age. To escape, Vermouth kidnaps the unconscious Conan and while escaping from Jodie's car, shoots the gas tank of the remaining other car to prevent being followed.
She receives a text from the boss telling her, "It looks like I have given you too much freedom. Come back to my side, Vermouth." She replies to the boss's text and Conan records to sounds of the dialed number. Conan, who has woken up some time before, tells Vermouth to take him to the boss or he will transmit the boss's number. Vermouth escapes via sleeping gas and shooting herself in the leg to keep herself awake while Conan dozes off. She destroys the recorder Conan has with him, but he remembers the boss’s phone number by sound anyway. She leaves her coat on Conan to prevent him from getting cold. She calls Gin from a payphone and tells him to pick her up, saying she had been caught by Shuichi Akai and wounded by him. Gin asks her if she knows someone named Shinichi Kudo and she lies, saying she doesn't know. She leaves with the thought that Shinichi Kudo, since he could touch her heart, might be the Silver bullet that destroys the Black Organization.
The real Dr. Araide returns and helps with a school ghost mystery case. He seems to only know the basic details of the impersonation he was the victim of. Conan puzzles over why Vermouth disguised as Araide joined the primary/high school rather than a university when it is clear that Ai would have been too old to attend one. Araide seems surprised when Ran says he is nice and in the end he gets a call from Jodie. Araide says he is surprised how well liked the disguised Vermouth’s Araide was based on student/teacher testimony and asks Jodie if Vermouth is really a bad person. Jodie becomes exceedingly grumpy and yells at Araide.
 Cellphone arc
Several times, Conan involuntary recalls Vermouth dialing the boss while watching other people dialing their phones. The sound of the number being entered, Nanatsu no Ko, unconsciously makes him feel Vermouth's expression was sad and dear.
Vermouth makes her first appearance since the confrontation with her prior in the back of Gin's Porsche when he and Rena meet to discuss the details of an upcoming assassination. The primary plan didn't involve Vermouth, instead Kir would lure the target, DJ, to sit on a bench where Chianti and Korn would snipe him. Chianti is very displeased that Vermouth is present, believing that she used Calvados' infatuation to use him in an irresponsible plan that got him killed. Vermouth teases Chianti by blowing her a kiss and wishing her good luck to spite her. Chianti and Korn later comment to each other in private that they would like to kill Vermouth even though she is the boss's favorite. Vermouth sat in the back of Gin's car in the parking lot during this first plan and was shocked to see Conan and Jodie arrive in Agasa's car to to intercept the assassination. She says nothing to Gin and Vodka and instead wonders how Conan will manage.
The failure of the first plan due to Conan and Jodie's actions initiates the second plan. The Black Organization agents assemble in an abandoned building by the water to discuss the details: Vermouth on a motorbike, in disguise as an opponent of DJ, will crash in front of DJ's car. When DJ exits the car, Kir will come up from behind and shoot him. As the planning wrapped up, a certain comment from Kir prompts Vermouth to ask if she was a NOC, which Kir denies offhand.
The second plan was never executed because Kir was captured by the FBI on the way to the rendezvous point and Gin discovered the tracker on Kir's shoe that allowed Conan to overhear the plan. Gin contacts the boss who calls off the assassination and approves a new target: Kogoro Mouri whom Gin believes is the tracker's owner. Conan arrives just in time to block the snipers' shot, and Gin tells Chianti and Korn to kill him along with Kogoro. Vermouth objects to this assassination, pointing out he is heavily involved with the police. Gin asks her at gunpoint if there is something between her and Kogoro. Her reply "my, my, if there was, what would you do?", satisfies Gin enough to take his gun off of her, but not enough to call off the murder. Shuichi Akai's timely interference stops the assassination completely and the Black Organization retreats. In the car, Vermouth points out that it all seemed to be a trap by the FBI with Kogoro as the bait. This explanation seems to satisfy everyone but Gin who still has some residual suspicion of Kogoro.
As part of the Organization mission to uncover the fate and whereabouts of their missing agent Kir who the FBI captured in the events of Organization vs. the FBI, Vermouth interrogates a kid present at Kir’s motorcycle wreck and subsequent capture and discovers Kir was injured and is most likely in a hospital. Acting on this intelligence, the Organization begins dispatching agents to search hospitals in secret.
Vermouth was ordered by the boss to find and follow Akai's Chevrolet when the FBI were moving Kir in the three vans. To Gin's annoyance, she was late with her report because Akai parked far from the hospital. She later sneaks up on and examines Jodie Starling and James Black's reactions to the news that Akai died, seemingly in order to test if Akai's death was genuine. She thinks to herself that the remaining "silver bullet", Conan, is enough.
Sometime offscreen after Red versus Black, Vermouth was approached by Bourbon with a request. Bourbon didn't initially believe Shuichi Akai was dead, so he had the idea to disguise as Akai to uncover the truth. He would approach Akai's close friends and colleagues and observe their reactions to him in order to see if Akai was dead. Bourbon asked Vermouth for her disguise assistance, and also made a promise to Vermouth, perhaps in exchange for her help. The boss approved their plan out of an abundance of caution, but Vermouth and Bourbon failed to tell Gin and the other members about it. Vermouth then disguised Bourbon as Akai with a large scar on his face.
Their failing to inform the other Black Organization members of the plan backfires when Gin hears about "Akai" and attempts to have him assassinated. Vermouth pulls up in front of Gin as "Scar Akai" leaves the department store. She warns Gin not to shoot Scar Akai because he is Bourbon in disguise. She gives an affirmative when Gin asks if she had the boss's approval for this plan which they had failed to mention to him. She mentions the plan was an extra precaution to make sure Shuichi Akai was dead because the boss is a very cautious person.
Vermouth called Bourbon while overlooking the traffic-accident aftermath of a case where Conan had been taken hostage. Amuro then answered the call. Vermouth told Bourbon that had he had "gained some trust" and she hoped that he would keep the promise he made to her. At the time, Vermouth was alone on her motorbike observing from an overpass.
When Bourbon uncovered a video of Shiho Miyano that showed she was going to be on the Bell Tree Express, he reported it to Vermouth, who then reported it to Gin. When Vermouth called Gin to inform him of the video, he was pleased and confided that he was worried she might have been hiding sympathy for Shiho. She told him that was nonsense, and not to interfere with her plans until the train arrives at its final destination. Bourbon and Vermouth decided to team up in order to capture Shiho, however, although Bourbon wanted to capture Shiho alive, Vermouth intended to kill her and had altered Bourbon's plan without telling him.
It was decided that Vermouth, who could impersonate Akai's voice, would don the Scar Akai disguise and use it to trick Masumi Sera so they could get her out of the way and intimidate Shiho into fleeing to part of the train where Bourbon lay in wait. Vermouth figured that Haibara would take an antidote and become Shiho to avoid revealing her deaged state, and she would then run away from her friends so they would not be in placed in danger. Strategically placed smoke canisters would simulate a fire in the back carriages of the train. The known pyrophobic, repeat-riding passengers in the second to last carriage, along with Bourbon yelling fire, would cause all the other passengers to evacuate forward while Shiho would run towards the back of the train. Bourbon would then confront her alone there, knock her out, move her to the luggage car, and detach it with a small bomb so a helicopter trailing the train could collect her alive. This would also stop the train from arriving at the final destination in Nagoya where Gin has planted a large amount of C-4 to blow the entire train up. Unbeknownst to Bourbon, Vermouth had modified his plan by filling the luggage car with leftover C-4 so she could detonate it as soon as Bourbon detached it and kill Shiho.
Vermouth and Bourbon follow their intended plans. Vermouth had bugged Agasa's room to keep abreast of what the Detective Boys were doing. Vermouth then intimidates Haibara by glaring at her in passing while disguised as Scar Akai and then sending her a threatening text message. Haibara, as expected, attempts to flee from her friends. What Vermouth did not anticipate was a murder taking place in the train leaving a vacant room for Shiho to hide in, that Conan, Yukiko, and Subaru Okiya were working together to foil the plan, and that Kaitou Kid was on-board scoping the train for an upcoming heist. Haibara goes to the empty room where Yukiko intercepts her and tells her of their own plan.
Meanwhile, Bourbon informs Vermouth when Masumi passed by alone so Vermouth in disguise as Scar Akai could intercept her and get her out of the way. On the way to get Masumi, Yukiko Kudo walks by and challenges Vermouth to a "battle of wits" where Vermouth would have to truly give up on Shiho forever if Conan outsmarted her on the train. Vermouth then confronts Masumi, knocks her out with a stun gun, and moves her to her room. Vermouth then mails Bourbon that she had "removed the obstacle, so the rest should go as planned".
Fearing Yukiko's plan, Vermouth looks up Yukiko's room on the passengers list and searches through her cabin. She finds supplies that Yukiko seemed to be intending to use to disguise as Shiho and fake her death, so Vermouth throws them all out of the train. Yukiko then confronts Vermouth directly, and Vermouth rips off her Scar Akai mask. Vermouth expresses surprise that Yukiko was involved in the battle between Conan and the Black Organization, and Yukiko replies that she had involved herself. Yukiko then taunts Vermouth over her unaging state, and that the great Sharon Vineyard was nothing more than makeup. Vermouth questions Yukiko about her plan, and Yukiko teasingly reveals a few details such as Masumi being retrieved from Vermouth's room already. Yukiko returns to the topic of unaging, explaining that her side has an advantage over Vermouth because she does not want her unaging state revealed and has kept Conan's and Haibara's state a secret from her coworkers. Yukiko then draws the connection to Suguru Itakura, a CG artist who had worked with Sharon in some movies with visual effects. Yukiko explains that she learned from Conan that Vermouth had ordered some software from him, and she had heard that Sharon and he had uncharacteristically quarreled. Yukiko wonders if that is relevant to Vermouth's state and secret-keeping.
Not wanting to continue with this line of questioning, Vermouth cuts Yukiko off by drawing her gun and revealing that she has seen through her "fruitcake of a plan". Vermouth explains how she knew Yukiko intended to disguise as Shiho and pretend to be killed, and she ruined it by throwing all the disguise materials out. When Yukiko gets a call from Conan, Vermouth takes the phone from Yukiko and answers it in her voice; Conan announces he can't find Haibara anywhere. Falsely thinking Conan was deceived, Vermouth hangs up, and then explains her and Bourbon's plan to Yukiko. Vermouth activates the smoke canisters, and as predicted everyone flees to the front of the train to avoid the fire except for "Shiho", who is really Kaito Kid in disguise, who runs to the back of the train. Bourbon confronts her there and forces the fake Shiho into the luggage car where she reveals that Vermouth had tricked Bourbon and planted bombs to kill her. Bourbon tries to get Shiho to leave with him, but Shiho shuts herself in, and Akai separates the train cars like Bourbon originally intended with a grenade. Hearing the explosion, Vermouth triggers her bombs to detonate and blows up the luggage car. Yukiko acts defeated and Vermouth leaves triumphant. Vermouth then quickly disguises herself as a woman with braids to avoid recognition when the train stops prematurely.
Vermouth realizes she had been tricked when she sees Haibara Ai draped over Agasa's shoulder and figures out Kaitou Kid had posed as Shiho Miyano and escaped the luggage car before it exploded. She also realizes Conan had feigned ignorance on the phone earlier so Yukiko could continue to hold her up. She mentally congratulates Yukiko for "excellent casting". Bourbon, who had seen the figure of Akai through the smoke, asks Vermouth if he can review the files on Akai's death again.
After Bourbon and Conan finished solving a case, Vermouth is shown in the last scene talking to him while taking a bath. She asks how longer he plans to stay with Kogoro Mouri and notes that ever since Conan planted a bug on Kir's shoes, he has been wanting to monitor Kogoro's actions. Vermouth lies to Bourbon and keeps her promise to Yukiko about laying off Sherry by assuring him that they were able to "send Sherry to her grave". Bourbon replies how his interest has been piqued in 'Sleeping Kogoro' while thinking about Conan implying that he has deduced the secret behind the 'Sleeping Kogoro' act.
