S01E584 — The Lost Love of Inspector Shiratori

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. Kobayashi is unable to remember the event and replies it must have been Sato. Later that night at the school, Kobayashi receives a phone call asking to meet her at the music room when a presence behind her shocks her.
