The Whisperers (Charlie Parker Series #9)

Evil has dogged Charlie Parker’s steps, costing him his career as a cop and his license as a private investigator. Now, as veterans begin dying mysteriously, he is called in to stop the bloodletting. But the smuggled objects have attracted the attention of the reclusive Herod and his henchman, the shadowy figure he calls the Captain. To defeat them, Parker must form an uneasy alliance with a man he fears more than any other: the killer known as the Collector.
