 File 939 - Lunch at the Department Store!
Agasa has once again won a meal ticket and is taking the Detective Boys to a restaurant at the department store. On the way there Conan thinks over what he knows about Masumi and the girl who is living with her, who he thinks is named Mary. He starts to think that she might resemble someone else, but his thoughts are interrupted by Haibara. When they arrive at the department store they see it decorated for Christmas despite it not being Christmas yet. Ayumi and Haibara approach the makeup counter. Haibara demands that they get to try on some makeup since they are customers, but the counter workers try to deny them and ask where their mother is. They get the makeup anyway and the counter worker asks about Haibaras mother, and she responds that her mother has been dead since just after she was born.
After the meal Agasa reveals another surprise, that he had also won a shopping ticket so that they could buy themselves early Christmas presents. Ayumi, Genta, Mitsuhiko, and Haibara all walk off. Conan and Agasa observe the restaurant chef, Ujiyasu Hosogoe, getting told by another chef that a troublesome customer had called again, Ujiyasu told them to tell the customer to meet him in the stairwell. After half an hour passed Conan hears screaming coming from the stairwell and rushes in to find Ujiyasu has been stabbed. He said that the culprit ran down the stairs so Conan has the Detective Boys run to the stairwell and watch to see if the culprit ran down. The police are able to round up three suspects. The Detective Boys give three completely different descriptions of who they think is the culprit is, and Genta mentions that he thinks the culprit had the number 2 on them.
 File 940 - Taking apart the Testimony
The first suspect, Takashi, says that he had been looking for an empty restroom. His hand was wounded when caught in the restroom door and he has a bandage on his right index and middle fingers. He has two kanji characters on the back of his hoodie. The second suspect, Mitsuko, had lost her wallet and had been running from floor to floor to find it, however it had been in her bag all along. She had been in a hurry to catch a tv show. She is wearing a face mask due to being sick, and it had gotten worse as she had been running. She has a broach that looks similar to the number 6. The third suspect, Masaru, was sweaty from eating Thai food and was hurrying to get home so that he could shower. His original reason for coming to the mall was because he heard that a soup served in a restaurant there was the same as one he served at his own restaurant. His sports jacket has the Tokyo Spirits logo with an overlapping T and S on it. In addition he had been limping a little due to athletes foot. All three suspects had known the victim. Takashi had worked for Ujiyasu in the restaurant until he was dismissed for bad behavior. Mitsuko lives next door to Ujiyasu, and her dogs often barked to loudly which disturbed him. Masaru had accused Ujiyasu of stealing his recipes three years ago which ended with a fight where they were both taken to the police.
Conan points out that the knife used to stab the victim had no fingerprints on it so the police ask the suspects if they had gloves. All three of them had gloves because it is cold outside. After the police leave, the Detective Boys go into more detail about their statements with Conan. Genta had seen the culprit as they passed by several members of the Haido High Basketball team. Mitsuhiko had seen the culprit as they had run through a grouping of mannequins and small billboards. When the culprit passed Ayumi, they were standing between her and a window, where light was shinning in and obscured the view. They had reached down as if they were scraping something off their shoe. Then a group of High School students passed through on a study tour, blocking Ayumi's view again.
