WAS it Miss Scarlett, with the revolver in the dining room, or Professor Plum, with the lead pipe in the library…?
That's the poser prompted by the stage show Cluedo, which is based on the classic board game of the same named and the hit film Clue.
The comedy thriller stars ex-EastEnder Michelle Collins as Miss Scarlett.
She and fellow familiar board game names Professor Plum, Mrs Peacock, Reverend Green, Mrs White and Colonel Mustard arrive at a party one stormy evening, they are surprised to find they have all received the same intriguing invitation from Lord Boddy.
It soon becomes clear that they all have something to hide as the mystery and hysteria grows and the inhabitants of Boddy Manor are killed off with a variety of familiar weapons, leaving everyone to wonder who will be next.
Cluedo runs in the Lyceum Theatre from May 23 to 28.
Tickets can be booked through the Box Office in person, over the phone on 0114 249 6000, or at sheffieldtheatres.co.uk.
