Dead by Dawn

When his young son is viciously murdered by a classmate, a grieving father with a history of violence kidnaps the child responsible, igniting a frenzied manhunt fueled by a powerful politician -- the father of the kidnapped boy.

Unable to process the death of his daughter, Detective Boyd embarks on a hunt for a serial killer who murders according to a brutal tribal ritual: Muti. The only person who can help Boyd is Professor Mackles, an anthropologist who hides an unspeakable secret. The line between sanity and madness thins as Boyd goes deeper into the killer’s world.

A tough detective who is part of an elite New York City unit is trying to find out who killed his partner, but uncovers a plot to kidnap mobsters for money.

Charles Dobbs is a British secret agent investigating the apparent suicide of Foreign Office official Samuel Fennan. Dobbs suspects that Fennan's wife, Elsa, a survivor of a Nazi Germany extermination camp, might have some clues, but other officials want Dobbs to drop the case. So Dobbs hires a retiring inspector, Mendel, to quietly make inquiries. Dobbs isn't at all sure as there are a number of anomalies that simply can't be explained away. Dobbs is also having trouble at home with his errant wife, whom he very much loves, having frequent affairs. He's also pleased to see an old friend, Dieter Frey, who he recruited after the war. With the assistance of a colleague and a retired policeman, Dobbs tries to piece together just who is the spy and who in fact assassinated Fennan.
