At some point or another we've all taken part in a murder mystery - be it at a party, over a game of Cluedo or simply wink murder when we were kids. But you've probably never played it like this.
Over the course of a day we served up interactive clues and puzzles for all you social media detectives to solve and ultimately work as a team track down our murderer.
Each clue was followed by a poll to crowd source the answer and although those polls are now closed, you can still scroll through the murder mystery below, but make sure you don't scroll too far and reveal the answer!
