Twice A Spy picks up two weeks after Once A Spy left off, with Charlie, Alice, and Drummond hiding from the Calvary (the super secret, off-the-books, black op group hunting them) in Switzerland. Alice spends the time trying to clear their names, while Drummond undergoes experimental treatment for his early onset Alzheimer's. Charlie, well, he's doing what he does best: dry, witty humor.
Things don't stay this peaceful for very long though; Alice is renditioned (kidnapped) by a group of men in black, and Charlie is told that if he doesn't trade one of Drummond's hidden ADMs, well, they're going to see just how many pieces Alice can be carved into. Starting with her face.
With that image in mind, Charlie and Drummond set off to Martinique, where Drummond has a hidden ADM. Maybe. Somewhere. Finding the ADM is only part of the problem though, as they also have to deal with a host of other problems, including the Calvary, the CIA, mercenaries, Drummond's not-always-there-ness, and being thrown into prison, to name but a few.
Thomson has once again written a clever spy novel, while turning the genre on its head by featuring a spy who can't always remember that he used to be a spy (but always knows how to hot wire a car), a brilliant, but clueless guy who thinks in betting analogies, and a Shaoliln kung fu master who is trying to keep them all alive. This is a great book for anyone who likes spy novels, dry humor, and excellent writing.
