Vacancy (S05E17)

When one of two bridesmaids is found murdered in their hotel bed, Detectives Goren (Vincent D'Onofrio) and Eames (Kathryn Erbe) initially suspect two men that the women met in a bar. But when the survivor, Alice's (guest star Emily Bergl) story keeps changing, evidence suggests an actor – Tim, (guest star Desmond Harrington) posing as a taxi driver might have played a role. The detectives peel back the layers of the suspect's life and discover disturbing evidence, family history – and his penchant for researching twisted subjects for future acting assignments. (iTunes)
