Murder Island

TMDB score: 5.5/10

Murder mystery with a twist - the investigators are members of the public, competing to find the killer and pocket themselves £50,000. The body of Charly Hendricks has been found at an old run-down property she was renting from the local pub landlord. It's up to four pairs of amateur sleuths to search the scene and unpick the clues, hoping to find a motive for the crime.
