S1·E20 Ghost of Prickly Rose

While investigating the death of a wealthy businessman who died from a fall at a house reputed to be haunted, Remy and the team try to disapprove of the theory that the ghost of a scorned woman is behind it who shows up to murder three men every seven years. While Remy deals with a persistent female reporter, whom he once had a tryst with, Anne volunteers to go undercover at a local escort service to look for clues, while Smiley decides to moonlight at a taxi driver only to have his uncle's cab damaged by another falling victim.
