Chief Investigator Isaac Bell of the Van Dorn Detective Agency has had many extraordinary cases before. But none quite like this. Hired to find a young woman named Anna Pape who ran away to become an actress, Bell gets a shock when her murdered body turns up instead. Vowing to bring the killer to justice, he begins a manhunt which leads him into increasingly more alarming territory. Anna Pape was not alone in her fate – petite young blonde women like Anna are being murdered in cities across America. If Bell is right about his fears, then he is on the trail of one of the greatest monsters of his time.
