The short story "garden of beasts"

Paul Schumann, a German American living in New York City in 1936, is a mobster hitman known as much for his brilliant tactics as for taking only "righteous" assignments. But then Paul gets caught. And the arresting officer offers him a stark choice: prison or covert government service. Paul is asked to pose as a journalist covering the summer Olympics taking place in Berlin. He's to hunt down and kill Reinhard Ernst -- the ruthless architect of Hitler's clandestine rearmament. If successful, Paul will be pardoned and given the financial means to go legit; if he refuses the job, his fate will be Sing Sing and the electric chair.
