A Sinister Obsession by S. B. Redstone

A psychopathic killer on a quest leaves behind a string of brutal murders, and to find the Who, the police must first discover the Why...

Detective Aubrey McKenzie has been assigned to investigate the murders. A lovely, fabulously wealthy, dark-haired Scot, whose iron will was forged in the inferno of human tragedy, Aubrey is stymied by the lack of solid clues. Now she must rely on her paranormal ability to apprehend the killer—an ability that has been invaluable in her police work but has made a disaster of her social life.

Fate teams Aubrey with Detective Joshua Diamond, a handsome, talented, and compassionate man who is more than happy eating a greasy bacon-cheeseburger and wearing clothes that should have been thrown out with the trash. In a race against time, Aubrey and Joshua must overcome their vast differences—and their attraction for each other—and discover the identity of this elusive killer, and the quest this fiend is on, before more lives are destroyed.
