The Scooby-Doo Show
Decade was smuggling records out of the studio in trash cans in order to sell them for personal profit. When a music writer, Tony Synes, realized his actions, Ace disguised himself as the Phantom and kidnapped Symes, locking him in a cupboard in the cafeteria.
Decade attempted to mislead the gang whilst they attempted to solve the mystery, leading them to a tape recorder wired to the intercom in his office in order to give the appearance he was being framed. However, Synes left a clue, which was his ultimate downfall; his last piece of music spelled the culprit's name in the first three bars: ACE DEC ADE.
