CO-ED SLAIN. That’s the call that brings St. Louis Police Lieutenant George Hastings to the downtown banks of the Mississippi River, where Reesa Woods has been strangled and dumped. The hard-charging Hastings is no stranger to murder, but he’s stuck without any leads until a second body—also strangled—turns up across town and he knows he’s chasing a monster.

A talented doctor with an otherwise ordinary and enviable life, Raymond Sheffield has some very dark needs. His first victims are targets of opportunity, but his ambitions go far beyond that. He’s formed a taste for killing, and his only interest is in getting better at it.

As the violence mounts, the line between upstanding citizens and their secret desires gets thinner and thinner in this thrilling game of catch-me-if-you-can from acclaimed crime novelist James Patrick Hunt.
