Susan Ryeland is a successful editor – but her career is threatened when the new mystery novel by her number one author turns up with its final chapter missing. Her life is further complicated when she becomes involved in a murder.

Unwillingly, she finds herself cast in the role of an “investigator” out of her comfort zone as she tries to work out who killed her most successful author. The answer, she soon discovers, is buried somewhere in the novel he has written.
