Ran and her friends discuss how Kogoro san is always coming home late recently and is quite suspicious. Sonoko teases her and says maybe he has a new mistress. Conan has a another theory though and says that the food on his toothbrush and coming home drunk means that he is enjoying himself drinking somewhere. This enrages Ran and she starts bad mouthing her. An passerby scolds her and says she shouldn’t be talking badly about Kogoro especially since she does not know him. Shocked by this Ran replies that Kogoro is her father. The lady explains that Kogoro helps her for free with many cases and problems that she has and that he is a good man. Both Ran and Conan follow the lady home to see if what she says is true. They find out the lady is a landlord to an number of apartments, the lady invites them inside her home for a meal, meanwhile the doorbell rings and there stands a man dressed similar to Kogoro. Realising the man is an imposter Ran blurts out who are you and the man also asks the same question. The old lady is surprised and says this is Kogoro the great detective, however before Ran can blurt out this is untrue. The man pulls Ran’s hand and has a private word outside. There he admits that he is pretending to be the detective because he wants to please the lady since he’s going out with her granddaughter. Later Conan solves the case of why the TV is turning on mysteriously because the remote is under all the mess and the buttons is being pressed. While he solves this next door a murder has taken place.
