The Vegas Psycho Murders — Richard Banko

Slade Stone had been a private detective since he was a young man. It's the only job he's ever known. He's dealt with every kind of case imaginable, from kidnapped pets, unfaithful spouses and messy divorces to international fiascos that nearly ended the global economy as we know it. But in all Slade's years and vast experience, he had never encountered a case quite like the Vegas Psycho Murders. A case with so many twists and turns that for the first time in his life he can't make two and two add up to four. An unknown entity keeps screwing with the evidence and Slade's head, making this the most baffling case of his career -- and the most horrific.
