I can't help feeling this has been used in a crime novel but offhand I can't think of one. An actor on stage was supposed to commit suicide by cutting his throat. He picks up the knife thinking it's the usual blunt stage prop and finds out too late that it's a real knife. Fortunately he survived to tell the tale and the audience having applauded a brilliant special effect were shocked when the 'corpse' got up and staggered off stage.
The police are investigating.
