The Wandering Artist Murder Case

Situation
While at a painting exhibit, Conan notices a man in rag examining a picture. The next day while playing baseball with his friends, he notices the man again. After being asked about his drawings of a home, the man realizes he has been drawing unconsciously, and holds his head in pain. In the hospital, he was revealed to have been affected by amnesia and the pain was his returning memories. The man leaves the hospital. The next day while playing baseball, Genta finds the man dead.

Resolution
« Hide spoilersConan finds out that the man is Tatsuo Hayase, an artist who's been missing for a year. His wife, Kimie, is the only one who can identify the body but she proclaims it's not him. Conan proves that the murdered man is Tatsuo by the fingerprints he left behind when he came home after regaining his memories. Conan reveals that the murderer is Kimie Hayase. In the past she tried killing her husband to inherit his life insurance money then successfully did so again to prevent him from threatening her and revealing all to the police.==Trivia==
 * Takagi smokes in this episode in order to reveal that Kimie dislikes smokers, contradicting a later plot in the movie 11, Jolly Roger in the Deep Azure where Takagi fakes that he is a smoker in order to get fingerprints from a suspect. The reason for this contradiction may be because this episode occurred well before Takagi was fully characterized and the storywriters decided to make Takagi a non-smoker later. It's not unlikely, however, that Takagi is or was merely an occasional smoker.
