Don't Look a Cold Case in the Cadaver

For psychic P.I. Piper Ashwell, having to teach a class of criminal justice students about assessing crime scenes is stressful enough. What makes it much worse is reading the cadaver in the class and discovering the deceased was murdered.The coroner's report states the death was a heart attack, but Piper knows better. The problem is figuring out how to prove something that was never even suspected in the first place. Time has erased all evidence of the poison that killed the victim, and Piper can't convict a killer on psychic abilities alone.Will this be one cold case she can't close?
