[Simon had faked his own death in the past. This time he really is dead. Peter, Beatrice and Aunt Auriel are looking wistfully at his gravestone
Amazing to think he's actually down there this time.
You were quite sure he was dead?
Oh yes. As was the doctor. And the pathologist. And the undertaker.
Always pays to be certain with Simon.
