A hiker is killed in a public park-seemingly a random act of violence. With no leads to follow, the case stalls until a tip comes in. Kevin Mathers, an outside consultant known for bringing down a serial killer, is called to help.

As Kevin uncovers new clues, the police question whether the murder was an isolated incident. Then more bodies begin to appear-each death connected, in some way, to the first killing. Kevin and the homicide team chase every lead, only to find the investigation turning dangerously personal when the killer strikes close to home in a spasm of murderous rage.

Relentless in his pursuit, Kevin finally comes face-to-face with the killer in a heart-stopping fight to the finish-an unthinkable showdown in the very park where it all began.

"Warning: If you're from Philly and up for a hard-boiled why-dunnit, you might want to avoid the Roxborough environs, while you read this galloping narrative, spiked with first-person glimpses into the mind of an unlikely killer. Kevin isn't a cop, but his part in the earlier apprehension of a serial murderer has left him with hero status, a homicide detective for a best friend, and incentive not to turn away from a murder in Fairmont Park until the perp has been brought to justice. Fasten your seat belt as Steven Fisher takes you along for the ride." - Helen Foster, author of Tidal Overlook, Lost Graces, and The Silent Hen
