Quinnan (4) - S18.E9

The operation appears to be in jeopardy again when Petrit declares that he is going in search of his missing sister. Following a lead from a girl at a café, he and Carver visit a pool hall, but have no joy with the doorman. Page meets up with Cullen to give him an update, and tells him that she is convinced that they are being set up for extortion by Berisha. Her suspicions are later confirmed when Berisha presents Quinnan with a bill for excess staff. Initially, he refuses to pay, until Berisha starts to strangle him, watched by a helpless Webb and Lennox. A determined Petrit plans to return as a punter to the pool hall where his sister may be, which is identified as a brothel.
