As with all of Desmond Bagley's books, this one has plenty of action and adventure, plenty of exotic locations that Bagley handles as if he'd lived there for his whole life, and interesting yet plausible characters handled deftly and smoothly; like almost all of his novels, this one also has a puzzle that keeps the reader guessing for the whole book. If there's a flaw with it at all, it's that he withholds a bit of the information that his main character has for just a chapter or two, so that the reader has no chance of solving the puzzle before the main character spells out the solution. But that's a small price to pay for this delightful book, and I highly recommend it as I do most of Bagley's ouvre.
