S15·E1 Long Term Investment

Deakin's surveillance on convicted kidnapper Frank Tully's release from custody is immediately blown out when Tully spots them, revealing his already released partner in crime told him he was also under surveillance. Deakin then confronts his partner, Richard Hackett, demanding information on a missing ransom payment from a kidnapping 8 years earlier. Deakin sends Holmes undercover as Hackett's girlfriend, but when they set up an observation, Tully pulls a gun on Hackett and Holmes after discovering there is no money in their safety deposit box. Tully is arrested when Hackett reveals the gun is empty, and suspicion turns to bank manager Roger Carlson, who decided to go on holiday the day of the raid. However, when all he is found with is a small bag of heroin in customs, they discover he may have been framed for someone else to steal the money without Hackett or Tully's knowledge.
