Case

Situation

Mamoru Kokubo visits the home of his aunt, Naoko Kokubo, and finds that she's been murdered. Then, a hill myna named Nine and famed for ill-speaking people flees.

Murder
	Location: Naoko Kokubo's House Victim: Naoko Kokubo Age: 70 years old Cause of death: Strangulation Suspects: Mamoru Kokubo, Emi Yahagi and Yotaro Sayama

Naoko lived with her maid, Emi Yahagi. At the time of the crime, Emi had gone shopping and wasn't at home. It's discovered that Naoko, who gathered old books, was buying imitations from an old bookstore owner, Yotaro Sayama.

Inspector Megure believes one of three is the criminal but they all have alibis. Conan gets close to the case's truth going by what Nine says.

Resolution

  Show spoilers »

Naoko Kokubo was murdered by Yotaro Sayama, and the motive was her demand for restitution against Sayama for inadvertently selling her the fake book. The monetary recompensation, however, was not enough for her; she chose to humiliate him in any way she could think of, by forcing him to attend to her petty needs despite his arm injury and continually posting public apologies for his mishap. This finally pushed him over the edge, and when he saw the chance to rid himself of her, he killed her, inadvertently also causing Nine to escape from his cage. Sayama's alibi through his telephone call with Mrs. Kokubo was established because he kept walking towards her home while maintaining his conversation with her, instead of staying at the station where he received her call. She let him in through the side entrance to the house.

The decisive pieces of evidence for Sayama's guilt are:

• His statement that he saw the myna trailing a red string behind him, whereas Mrs. Kokubo had attached that piece of string to Nine's leg just on this very morning, and Nine later left his leg ring and the string in Kogoro's hands when he escaped from the police box.
• The flowerpot found near the door was carried inside by Sayama himself, after Mrs. Kokubo had ordered him to do so after opening the side entrance for him. Since Mrs. Kokubo was confined to her wheelchair, and since Mamoru und Emi were obviously surprised to see the pot at its odd location, this left Sayama as the only person who could have moved it.
• Sayama's complaint that something stinks in the living room - a phrase Nine has picked up before the murder occured - stems from Kokubo having ordered him to stir the odorous pickles she kept in her cellar. When Sayama returned and saw her sitting with her back to the trap door, he seized her stole from behind and strangled her with only needing one healthy hand.

Trivia

• A slight production mistake occurs in the second part of the episode, right after Ai and Ayumi have presented themselves as Emi Yahagi's witnesses. When Kogoro is seen chuckling at Megure's perplexity, the fluttering of Nine's wings can still be heard, but at the same time the myna's feet are already resting on the top of Kogoro's head.
