This is a smashing good crime novel with a modern tone and a plot that only Hitchcock could have done justice to. Screenplays were written for it but somehow it was never brought to the sceen. It should have been made into a film. Involving The League of Nations and Geneva in the early '20s, secret societies, villains and heroes, even a hint of sex slavery, this fast-paced thriller will keep you turning the pages and rooting for the good guys.
