Years after WWII, a pair of veterans believe they've spotted a Nazi in disguise

In postwar England, Goldsmith and Templewood see each other once a year at reunions of their regiment. Goldsmith is a local politician now, while Templewood is a gregarious salesman with a taste for the ladies. They lead different lives but have one thing in common: They vividly remember Nikolaus Hebbel of the SS, and they would both like to see him dead.

Now they find themselves together, watching a man staying at their hotel in London, checked in under the name Neil Housman. They're sure he resembles Hebbel — something in the mannerisms, the expression. They ponder whether their memories of twenty years ago are reliable. They follow the man in hopes of confirming his real identity — and finding out what he's up to.
