What a great idea for a book --- a murder mystery that takes place during the Second World War at the secret Los Alamos lab where the atomic bomb was developed and includes famous physicists in its plot. Too bad it fell apart so completely that my only motive for completing the book was to see if its plot was as lame as I suspected. Alas, it was. The author relies on the "idiot plot," with the main character behaving like a dunce solely to advance the story and prevent a premature conclusion. Why waste time on a book where you can guess who dunnit simply by the introductory description of a character? Furthermore, the moralizing in the book is superficial and serves only to fill pages up with words.
