Detective Abigail Brown is back. She earned a solid reputation after hunting down a dangerous serial killer in Moon Mask, but now the Detroit Homicide Detective is challenged in ways she could never imagine, by a new type of serial killer.
Rich and powerful men are being murdered in unthinkable ways, causing shock wave across the State of Michigan. They flaunt their political clout, pressuring police to find and bring the killer to justice immediately. Their demands only impede the ongoing investigations.
Separate killings of rich corporate raiders send the major case unit into overdrive. Each kill is different in method, and in every occurrence, there is no evidence or witnesses. Teams of homicide detectives work their cases diligently, but with little success.
Abigail Brown, a brilliant detective, has her work cut out for her once again. A trained profiler, she is convinced all the murders are the work of one killer. The only clues that back her theory are random numbers left behind at each crime scene.
