In his first case since he left the LAPD's Open Unsolved Unit for the prestigious Homicide Special squad, Harry Bosch is called out to investigate a murder that may have chilling consequences for national security. A doctor with access to a dangerous radioactive substance is found murdered in the trunk of his car. Retracing his steps, Harry learns that a large quantity of radioactive cesium was stolen shortly before the doctor's death. With the cesium in unknown hands, Harry fears the murder could be part of a terrorist plot to poison a major American city. Soon, Bosch is in a race against time, not only against the culprits, but also against the Department of Homeland Security and the FBI (in the form of Harry's one-time lover Rachel Walling), who are convinced that this case is too important for the likes of the LAPD. It is Bosch's job to prove all of them wrong. *** Harry Bosch is assigned a homicide call in South L.A. that takes him to Fortune Liquors, where the Chinese owner has been shot to death behind the counter in an apparent robbery. Joined by members of the department's Asian Crime Unit, Bosch relentlessly investigates the killing and soon identifies a suspect, a Los Angeles member of a Hong Kong triad. But before Harry can close in, he gets the word that his young daughter Maddie, who lives in Hong Kong with her mother, is missing. Bosch drops everything to journey across the Pacific to find his daughter. Could her disappearance and the case be connected? With the stakes of the investigation so high and so personal, Bosch is up against the clock in a new city, where nothing is at it seems.
