Multilingual, anarchic spy Evan Tanner once again goes behind the Iron Curtain in this 1966 seriocomic tale. This time, he must break into a Prague prison to liberate a despicable Nazi who will lead Tanner to the documents exposing his network of hatred. As is typical in Block's Tanner yarns, the spy has unusual allies: a gang of Israeli terrorists and a beautiful Czech nymphomaniac. Then Tanner and his charge, Janos Kotacek, make a painstaking journey through Hungary and Yugoslavia and finally to Portugal. The means he devises to silence Kotacek's racist rants, sneak him into the West, and trick him into revealing his secrets are extremely clever.
