This has got to be the worst book Ken Follett ever wrote.
The story is ridiculous. Would the KGB, at the height of the cold war, really let some English woman on one of their prized spy ships, give her free reign to move around, and relate to her all the details of their top secret sources and methods? Please.
And of course a flight attendant has the skills to outwit a ship full of hardened KGB agents, and figure out how to destroy the ship, all in a few hours. Hello! And by the way, Ken, diesel fuel cannot be ignited by a cigarette.
The style was completely naive and painful to read as well. Endless exposition outside of the action, a rough draft of a book at best. If you like spy novels, read "The spy who came in from the cold." That's how spy novels should be written.
People giving 5 stars for this tripe? Can you say "shill"?
