It doesn’t take a genius to see Albert Einstein’s life is in danger, but it will take a hard-headed Hollywood PI to save him. It’s all relative.   It’s April 1942, the world is at war, and LA private detective Toby Peters has been summoned to Princeton, New Jersey, to deal with a situation of the utmost gravity—the world’s greatest physicist is being threatened. Blackmailers claim to have evidence that Albert Einstein has been passing nuclear secrets to Russia, and Nazi assassins want to do away with one of the most famous opponents of Hitler’s rule. Sounds like a formula for disaster.   Peters is used to dealing with Hollywood’s elite—not exactly a brain trust—but the East Coast is a new beat for him. Soon he’s swept up in some serious Manhattan mayhem, trying to keep Einstein from harm but also trying to stay alive himself.   Incorporating cameos from Paul Robeson and Frank Sinatra, Edgar Award–winning author Stuart M. Kaminsky “has such a good time writing, and he so loves the period, that the reader is swept along willy-nilly” (TheNew York Times Book Review).
