Hard to believe Jack Higgins wrote this book. Plot thin, character development all but nil (and implausible where it does happen), story lines started and stopped. And the dialogue! So banal. Lots of cliches (Higgins was on a tight deadline?). And there was one character whose presence - and actions - made no sense whatsoever. More research wouldn't have hurt, either. Doesn't come close to what Higgins can do.
