A Dave Guerney Novel

A work that defies easy labels—at once a propulsive masterpiece of suspense and an absorbing immersion in the lives of characters so real we seem to hear their heartbeats—Think of a Number is a novel you’ll not soon forget.

It begins with a letter... The letter contains a request - think of a number, any number - and a sealed envelope. Inside the envelope is that number... When Dave Gurney, retired NYPD homicide detective, is contacted by an old college acquaintance about some startling letters he’s been receiving, it is at first little more than a diverting but sinister puzzle. Until the acquaintance is brutally killed.Suddenly Gurney finds himself in the middle of a murder investigation that makes no sense.

When he was the NYPD’s top homicide investigator, Dave Gurney was never comfortable with the label the press gave him: super detective. He was simply a man who, when faced with a puzzle, wanted to know. He was called to the investigative hunt by the presumptuous arrogance of murderers - by their smug belief that they could kill without leaving a trace. There was always a trace, Gurney believed. Except what if one day there wasn't?

As things grow more bizarre, he finds himself reexamining the case of The Good Shepherd, which 10 years before involved a series of roadside shootings and a rage-against-the-rich manifesto.

The daunting task that confronts Gurney, once the NYPD's top homicide cop: determining the guilt or innocence of a woman already convicted of shooting her charismatic politician husband. Gurney quickly finds himself waging a dangerous battle of wits with a thoroughly corrupt investigator, a disturbingly cordial mob boss, a gorgeous young temptress, and a bizarre assassin whose childlike appearance has earned him the nickname Peter Pan.
