THE GOOD ASSASSIN : HOW A MOSSAD AGENT AND A BAND OF SURVIVORS HUNTED DOWN THE BUTCHER OF LATVIA
by Stephan Talty 

The Nazi hunters were beginning to get very nervous. May 8, 1965 would be the twentieth anniversary of World War II ending. Both German politicians and regular citizens wanted the pursuit of  Nazi criminals to stop. A statute of limitations was about to expire. So, in other words all of these killers would be granted amnesty, come out of their hiding places and walk free. What to do? A mission was needed to annihilate one of the worst-of-the-worst monsters who'd escaped to South America, was never punished for his crimes against humanity, and then publicize it to the world to let them know how vile he and all the rest of them were. Amnesty needed to be blocked as much as possible.
The Nazi who was chosen was named Herbert Cukurs. His last name means sugar. How ironic since Cukurs was anything BUT sweet. He murdered thirty thousand Latvian Jews. Who would be the one(s) to accomplish this execution? Mossad, the Israeli national intelligence agency, jumped in. Jacob Medad (known as Mio) was chosen to lead the undercover operation. (He had helped kidnap Adolf Eichmann three years earlier.) Mio would become Anton Kuenzle, disguised as an Austrian businessman. He would go to Brazil, find Cukurs, befriend him enough to earn his trust, and then arrange the killing with the other agents.
Somehow I keep finding more stories on little-known Nazi war criminals. Kudos to all the authors who find out about them. Stephen Talty presents a heart-pounding tale of an extremely dangerous man known as the Butcher of Latvia. The writing, as usual, is superb. (I have read several of his previous books.) This is truly a riveting account by a master writer.
Highly recommended.
