Tensions are high as the squad investigates a possible copycat of the legendary Boston Strangler...or could it be the Boston Strangler himself? Meanwhile, Jane butts heads with her new boss, Lt. Grant (guest star Donnie Wahlberg), who just happens to be from the same neighborhood where Jane grew up. And Maura gets into trouble with her habit of diagnosing everyone - including her date.
