The Couch Murder

Detective Inspector Edward Wilkes of Notting Hill Station, London, is investigating an unusual case where an initially reported natural death turns into a murder investigation. A wealthy banker, Andrew Gibson, is found dead by his housekeeper, who assumed he was taking a nap. The murder evidence is a hypodermic needle found later at the scene of the crime, a couch in the victim's library. Wilkes and his partner, Smithers, look at Gibson's family, coworkers, and neighbors to piece together who could have committed this puzzling murder.
