Lane Koenig, in his late 50s, plays piano in the bar he owns in California and is haunted by memories of his brother's death 40 years ago. Just before WW II he and brother George were teen-aged, German-speaking but English-born recruits in Section D, a short-lived British intelligence operation. They, along .with equally young German-born Albert Lohman and Karl Kohler, were to report the movements of the Duke and Duchess of Windsor, whose sympathies the Germans were courting. One day at the Lisbon airport a car bomb, supposedly meant for the royals, blew up as Lane watched helplessly, and killed George and Albert. Now, 40 years later, Lane recognizes Albert in the entourage attached to the visiting Queen Elizabeth. If Albert lives, perhaps George too is alive! A trip to England and some dogged sleuthing bring forth another question. Why is someone trying to kill him? Tidy, imaginative plotting, given weight if not credence by the use of real names and characters. The prose tends to plod at times but the reader, along with Lane, will want to know the answers.
