The play in rehearsal at the Cornmarket Theatre has all the earmarks of a smash hit… if sabotage doesn’t bring down the curtain before opening night. Ghostly messages appearing o dressing-room mirrors, dirty tricks, and mysterious “accidents” begin to spook the cast, who believe the theatre is haunted by the angry spirit of Restoration dramatist Sir John Cartwright, the play’s author. But barrister-sleuth Antony Maitland is sure that the things going bump in the darkened theatre have a very human origin. And if he doesn’t unmask the joker jinxing the Cornmarket, the next act could be bloody murder.
