Immoral Certainty

He is the Bogeyman: a remorseless monster stalking the streets of New
York in search of fresh victims—his chosen prey being children.
 
The killings are ghastly enough to shock lawyer Butch Karp, who thought

child abuse case and a homicide case seem to be connected, Karp and his
colleague Marlene Ciampi find themselves delving into the darkest
corners of New York’s underworld.
 
Their chosen prey? A
cold-blooded predator whose twisted work has only just begun—and whose
true motives will force Karp to decide how far he is truly willing to go
to stop the horror.
