Gleen (S01E02)

The fiancée of fireman Rob Deamer (Brett Cullen) asks Lilly to help prove that Albert Miller (Mark Bernier), a convicted felon about to be paroled on an unrelated crime, is responsible for the murder of Rob's first wife. When Rob's daughter, Gwen (Jamie Brown), starts threatening Albert, Lilly discovers several disturbing facts about Rob, including relationships and secret marriages that ended violently. During her investigation, she uncovers evidence that could potentially clear Albert while leading directly to the true killer. (Warner Bros. UK)
