Susan Ryeland has had enough of murder. She's edited two novels about the famous detective, Atticus Pünd, and both times she's come close to being killed. Now she's back in England and she's been persuaded to work on a third. The new 'continuation' novel is by Eliot Crace, grandson of Miriam Crace who was the biggest selling children's author in the world until her death exactly twenty years ago. Eliot believes that Miriam was deliberately poisoned. And when he tells Susan that he has hidden the identity of Miriam's killer inside his book, Susan knows she's in trouble once again.
