Still reeling from the death of her fiancé, Detective Anna Travis has thrown herself into her new role as detective chief inspector in the city's murder squad. When a familiar court employee comes to the station, pleading for Anna's help in locating his missing son, she directs him to the team in Missing Persons. But after weeks with no leads, Detective Chief Superintendent James Langton, Anna's former lover turned friend, urges her to take the case. She agrees to take charge of the investigation—only her second as DCI—under his watchful eye. But is it purely a missing person case—or a full-blown murder inquiry? An ominous pool of blood and no victim lead Anna on a desperate hunt for a man who has disappeared without a trace. As Anna becomes obsessed with seemingly irrelevant details, James fears that she is losing control. They still have no body, and Anna is under increasing pressure to make an arrest.
