Sleeping With The Enemy - S15.E12

Skase and Lennox enlist the help of Burnside as they investigate a series of robberies at local business conventions. Burnside is reluctant to admit why but he identifies their suspect through a tattoo described by a victim of theft, a former prostitute using the alias Victoria Smith. He later admits to Holmes she tied him up and left him in nothing but a raincoat while she robbed him during an undercover op when Burnside was a newly-promoted DC. Lennox and Skase go undercover at the latest convention, and while Skase pulls, he is forced to abandon his attractive companion at the revelation she is an innocent who was actually attracted to him. Lennox has better luck, but when he and his companion go back to the hotel room, she drugs him and steals his laptop. When the woman is found in hospital, having been attacked by one of her victims, Burnside launches a raid to arrest her and Smith.
