Killing Poirot in the midst of this turmoil seems almost spiteful, but Agatha has a plan: she's selling the novel to a private buyer, a superfan who will pay anything to own a piece of history. A meeting at an infamous London hotel is arranged, where despite the presence of an old friend, things quickly go wrong. As the bombs fall and the bodies pile up, the real danger of her situation becomes apparent: the only thing more valuable than the last ever Poirot novel is the last ever book written by Agatha Christie.
