Tug of War - S2.E8

When Mannion has Temple and Debreno investigate the woman's murder, he discovers that the criminals weren't going for the victim's cash or credit cards, but for the expensive purse itself. In response, Mannion immediately dispatches detectives to patrol subway cars, angering the chief of the Transit Authority, who believes that Mannion is trying to muscle in on his territory. Then, when Debreno and Temple set up a sting operation, Debreno's life is put in danger and Mannion's team must find a way to draw out the perpetrators of these crimes before they strike again.

Also, Mannion's outrageous ex-fiancee comes back for a visit after hearing that Mannion and Sherry split up.
