Wanderlust

M1, T5: When a handsome travel writer is found murdered -- with a woman's panties stuffed in his mouth -- Detectives Benson (Mariska Hargitay) and Stabler (Christopher Meloni) focus on a pedophiliac (guest star John Dossett), the unassuming boyfriend of the victim's landlord (guest star and Emmy nominee Patricia Richardson, ""Home Improvement""). However, the key to the case might be the landlord's rebellious 14-year-old daughter (guest star Lynn Collins), whose casual, seen-it-all sexual maturity makes Stabler uneasy about his own 14-year-old as she eagerly enters the dating pool. Richard Belzer, Dann Florek, Michelle Hurd and Dean Winters also star.
