Crime scene / Jonathan Kellerman and Jesse Kellerman.

Enhanced descriptions from Syndetics:

Natural causes or foul play? That's the question Clay Edison must answer each time he examines a body. Figuring out motives and chasing down suspects aren't part of his beat--not until a seemingly open-and-shut case proves to be more than meets his highly trained eye.Eccentric, reclusive Walter Rennert lies cold at the bottom of his stairs. At first glance the scene looks straightforward: a once-respected psychology professor, done in by booze and a bad heart. But his daughter Tatiana insists that her father has been murdered, and she persuades Clay to take a closer look at the grim facts of Rennert's life.What emerges is a history of scandal and violence, and an experiment gone horribly wrong that ended in the brutal murder of a coed. Walter Rennert, it appears, was a broken man--and maybe a marked one. And when Clay learns that a colleague of Rennert's died in a nearly identical manner, he begins to question everything in the official record.All the while, his relationship with Tatiana is evolving into something forbidden. The closer they grow, the more determined he becomes to catch her father's killer--even if he has to overstep his bounds to do it.The twisting trail Clay follows will lead him into the darkest corners of the human soul. It's his job to listen to the tales the dead tell. But this time, he's part of a story that makes his blood run cold.
