Triple Trouble

The boys are on their way home from a masquerade party when they hear noises in a warehouse and decide to investigate. They find the warehouse is being robbed and they are mistakenly captured by the police and sentenced for robbing it. Gabe, as their lawyer, gets them off with just probation but Slip insists that he and Sach accept jail time in order to find out who is behind the series of robberies in the neighborhood. He deduces that the instructions are being sent from inside the prison via a short wave radio.
