Law & Order: Criminal Intent: Season 5, Episode 10

5 - 10: Dollhouse

The gunshot murder of a businessman perplexes Detectives Logan and Barek until they suspect that Danielle -- a self-involved mother -- has made a cottage industry of blackmailing other cheating family men with phony paternity claims. But the detectives discover that Danielle's seemingly meek and maternal sister Claire could be playing a far more sinister role in the scam.
