Ex-Detective Inspector Daniel Hawthorne is dead. Or, rather, the actor playing him in the film adaptation of The World is Murder is. Rising star David Caine has been stabbed, and it seems that everyone on the set had a motive. Caine had just fired his PA. He had fallen out with his director, slept with the screenwriter, humiliated his co-star and dropped his agent days before he was about to sign a multi-million-dollar deal to appear in the next Spider-Man movie. But what if Caine's murderer had made a mistake? What if it was the real Hawthorne who was the intended victim? For it turns out that the brilliant detective may have got it wrong ten years earlier. An innocent man has died in jail. And perhaps someone has decided that Hawthorne must pay the price.
