Pas de Deux (S03E13)

Donny De Palma (Charles Rocket) picks up a bored housewife named Margie (Enid Graham) at a dance class, but also has another partner named Ernie (Delaney Williams) who robs banks with him. Ernie wears a "fake bomb" around his neck and tells the bank teller, unless the rules are followed, the bomb will go off. The cops catch Ernie and the bomb, turning out to be a real one this time, goes off, killing him. Detectives Goren (Vincent D'Onofrio) and Eames (Kathryn Erbe) undertake an exhaustive search to find Ernie's partner, and finally find Donny through surveillance tapes. Meanwhile, he's testing Margie stealing a very expensive purse and Margie, who desperately wants to escape her dull, suburban housewife existence, gets more and more excited by her new partner. Margie's husband, Will (Geoffrey Cantor), who works in Connecticut and is rarely home, doesn't have a clue, but when Goren talks to him he starts to get concerned. (iTunes)
