Russian Love Poem

S1 E12: When a multimillionaire with a sordid sex life is found bound and slain, Detectives Benson (Mariska Hargitay) and Stabler (Christopher Meloni) try to penetrate a suspicious ring of soulless Russian immigrants whose fatalism and enigmatic cooperation leave them going in circles. As Detectives Munch (Richard Belzer) and Cassidy (Dean Winters) run down other leads, one possible culprit is Katya (Nadine Stenovich), a beautiful, cunning and likely illegal Russian who included the victim among her many boyfriends -- that is, until one of her male admirers (Olek Krupa) issues a curiously bogus confession. Dann Florek, Michelle Hurd and Chris Orbach also star.
