After having a premonition about the newest member of the Weltunkin Police Department, psychic P.I. Piper Ashwell isn't all that eager to meet Detective Scott. Piper knows this female detective has it out to prove she's better than Piper, even if Piper does have the higher conviction rate. But the case the police chief assigns to Piper and her husband-partner, Detective Mitchell Brennan, is tougher than anything Piper's ever faced. This serial killer is targeting people who harm children, exacting justice in his own way. To make matters worse, Detective Scott is working the case as well, which means Piper has to catch an elusive killer and beat the new detective to the punch.
