S11·E132 The Wee Small Hours

Marshall attends to a widow who thinks that she is being stalked, but whose son doesn't believe it. When Jarvis and Keane arrest a young man trying to break into her car, they discover a schoolboy crush that has spiralled out of control. Meanwhile a raid on an illegal drinking club gives Monroe a lead in the search for a driver who fled from the scene of an accident that left a motorcyclist with serious injuries.
