Dead Hero — William Campbell Gault

So it's come to this. Brock “the Rock” Callahan, former gridiron star turned private eye - peeping in bedroom windows. It's a dirty job, and not the kind Brock would normally take on. If he had a choice.

But an old teammate asked him for a favor: following a stray wife. And what begins as a dirty job, gets worse, much worse. Brock becomes a hunted man -- and the prime suspect in a savage murder.
