New York City. Central Park. For thousands of residents and tourists who fill it every day, it’s an enormous urban sanctuary. For one killer it’s the perfect hunting ground.
 
A young girl has been found dead in the Ramble, a secluded section of the park made up of winding paths, dense woods, and dead ends. Is she the first victim of a psychopath? Or a clue to other missing women in years past whose remains have never been found?
 
For the answer, Assistant DA Alexandra Cooper and Detective Mike Chapman follow a twisting trail of evidence that takes them deep into the city’s dark history—and deeper into the mind of killer whose work has only just begun.
