DeAnna Knippling writing as Dean Kenyon.

No idea is so good it can?t go bad. Frank Mallory is a private detective working for a new type of national detective agency: a well-organized one. Private Eyes, Inc., has the latest in data analysis, training techniques, cross-discipline integration, illicit back-door deals, and cynical programmers who don?t care what they have to do as long as they don?t lose their benefits while doing it. PEI has it all covered. The right mix of idealism and plausible deniability can work wonders. But that doesn?t mean that Frank?s in the clear when he starts work on a case involving the new designer drug Mindsight. Mindsight is a miracle drug. It won?t give you telepathy, but it comes close, triggering a wave of pure empathy that helps treat everything from domestic violence to schizophrenia. The problem is, if you take too much of it, you?ll understand someone else?s point of view?all the way to death. Of course a serial killer starts butchering Mindsight addicts. As if nobody could see that coming. All he has to do is ask nicely. And maybe offer a little something the victim can?t refuse. The real twist is when a Mindsight addict fights back?and takes down a cop, saying that he admitted to being the serial killer before he died. Frank?s hired to find solid, incontestable proof that the man, someone he used to work with, is actually the murderer, so a rich man's daughter, the purported victim can walk free. Seems straightforward, right? Right.--Amazon.
