The investigation into the disappearance of Emma Broussard, the daughter of the city's future mayor, brings Detective Michael Patton back into active service after a three-month voluntary absence from the LAPD. He must work out why the kidnapper seemingly wants him close to the investigation whilst tracking Locust, a serial killer that has already struck five times and is showing no sign of stopping.
In his most electrifying case yet, Patton must race against time to try and find Emma Broussard before Locust can finish what he's started. It's another game that Detective Patton has no choice but to play.
