Haunted - S15.E84

DS Stanton, DC Lennox and DC Proctor are on an obbo at a spooky old building called the Old Pumping Station, which is supposed to be haunted. The trio tell each other ghost stories: back in his uniform days, Proctor was assigned to watch the house of a serial murderer. Investigating a noise, he meets a young woman called Cathy, who turns out to have been on of the killer's victims. A skeptical Stanton reveals how a psychic's assistance with a case she worked on turned out to be a hoax. Lennox, when he was in the Glasgow police, meets a dying crime boss who promises revenge from beyond the grave.
