The reviews called it "A Play to Die For" after a woman was found dead in the front row. It didn't seem so funny the next night when another body was found-this time the playwright himself, his throat slashed. Detective Kathy Mallory of the NYPD Special Crimes Unit takes over, but isn't getting a straight answer from anyone. Not the lead actor, a movie star fallen on hard luck; not the lead actress, a nervous sort with a dependence on pharmaceuticals; not even the wardrobe mistress, working under an alias; and certainly not the twin actors so unnervingly convincing playing psychos. Now, backstage, someone has left Mallory a message on the blackboard: Tonight's the night. Nothing personal. It appears that she is being written into the play itself, a play about a long-ago massacre that may not be fictional after all. If Mallory can find out who's responsible, heads will roll. Unfortunately, one of them might be her own.
