The Final judgement - Daniel Easterman

A young boy is kidnapped and his captors make outrageous ransom demands. Desperate, the boy's father calls upon his estranged brother-in-law for help. Yosef Abuhatseira is the perfect man for the job: an Israeli patriot, a born hunter, a one-man army of survival skills. Yet nothing Yosef has ever experienced can prepare him for what the rescue mission reveals. The kidnapping, it seems, is only the beginning. Soon a series of killings leads Yosef to the sickening realization that someone is murdering survivors of Auschwitz. Now he must penetrate the deadly wall of secrecy that surrounds the organization responsible, before they can let loose another Final Solution on humanity.
