Love of Kobayashi-sensei

Shiratori has Kobayashi listen to the three suspect's voices and has determined none of them was the voice that shouted out and storms out of the police station. Haibara explains Kobayashi must have seen Sato and heard the rumors that Shiratori is only settling for Kobayashi in place of Sato. Shiratori attempts to rectify the misunderstanding and confronts Kobayashi revealing they met many years ago in a bookstore when confronting a pair of thieves.
