5x17 - Law & Order: Criminal Intent

Goren and Eames investigate after a bridesmaid, Megan, is found dead in the cheap motel room she had been sharing with Alice, another bridesmaid at their friend Tory's wedding. The two detectives start with investigating Pete and Jayson, the two guys the women had met at Brasserie Nylorac, but soon realise that Alice's story has a lot of holes in it, and the presence of cigar smoke around Megan, a young woman who hated smoking, leads Goren and Eames to suspect that the killer had a personal connection to Megan. Their investigation soon leads them to a cab driver named Lester Summerhill, whom they soon realise is an actor preparing for the ultimate role.
