HEADLESS RUSSIAN MOB PRINCESS LEADS DETECTIVES TO SORDID COVERUP -- When the daughter (guest star Alla Kliouka) of a jailed Russian mob boss is found decapitated, Detectives Goren (Vincent D'Onofrio) and Eames (Kathryn Erbe) suspect the murderous hit was a result of her tattletale book -- but further investigation reveals that one of her previous private school classmates had an even more sordid reason to execute her. They discover that an uptight, self-tortured real estate magnate (guest star David Thornton) might have feared exposure of his own dark childhood secrets and kinky alter ego if a second bestseller had been published. Jamey Sheridan and Courtney B. Vance star. TV-14
