The Traitor's Stage (1)

While cleaning Shinichi's house, Conan and Subaru overhear Ran and Sonoko talking about a musician about to release lyrics from a song written 17 years ago with the title, ASACA. Something about this leads them to believe it could be related to the Black Organization. When arriving at the musician's rehearsal, Amuro is there with Azusa from the Cafe....but it's Vermouth in disguise!
