From number one bestselling mystery author Blake Pierce comes a new masterpiece of psychological suspense.

In A Trace of Crime, Keri Locke, missing persons detective in the homicide division of the LAPD, follows a fresh lead for her abducted daughter. She winds her way through a twisted underworld, and step-by-step, she gets closer to finding her daughter.

Yet she has no time. Keri is assigned a new case: a dad calls from an affluent community and reports that his teen daughter vanished on the way home from school.

Shortly after, ransom letters arrive. Twisted, filled with riddles, they make it clear that there is little time to save the girl. They also make it clear that this is the work of a diabolical killer who is toying with them.

Keri and the police must scramble to find the kidnapper, to understand his demands, to decode the letters, and most of all, to outwit him. But in this master game of chess, Keri may find herself up against a foe even she cannot understand, and for the missing girl - and her own daughter - she may just be too late.

A dark psychological thriller with heart-pounding suspense, A Trace of Crime is book number four in a riveting new series - and a beloved new character - that will leave you turning pages late into the night.

Book number five in the Keri Locke series is also now available!
