Law & Order: Special Victims Unit: Season 11, Episode 21

Torch

Jo Marlowe, Stabler's old partner before SVU, becomes the new ADA for the SVU team and enlists the help of Benson and Stabler in the case of two young girls, presumably left to die in a burning house by their father. Upon further investigation by the SVU squad, however, it is discovered that the father, Frank Sullivan, did not set the fire that consumed his two daughters, later exposing the incorrect assumptions of a fire marshal (P.J. Benjamin) with the help of an independent pyrotechnic investigator (Brad Dourif). Sam Waterston makes a guest appearance as District Attorney Jack McCoy.
