It's Christmas in Houston, and homicide detective Roland March is on the hunt for a killer. A young woman's brutal stabbing in an affluent neighborhood bears all the hallmarks of a serial murder. The only problem is that March sent the murderer to prison 10 years ago. Is it a copycat - or did March convict the wrong man?
Alienated from his colleagues, and with a growing rift in his marriage, March receives a series of taunting messages from the killer. The bodies pile up, the pressure builds, and the violence reaches too close to home. Up against an unfathomable evil, March struggles against the clock to understand the hidden message in the pattern of wounds.
