This first book in the Troy series left me rather torn. On the one hand, it's a gripping page-turned stuffed with great characters and atmosphere, all set in London just prior to D-Day. On the other hand, the plot relies on so many coincidences and contrivances that one's suspension of disbelief is sorely tested. Like the Berlin detective Bernie Gunther in Phillip Kerr's excellent WWII trilogy (collected as Berlin Noir), Lawton's D.S. Troy is a wonderful character. Born in England to upper class Russian Jewish parents, he doesn't believe in Queen and country, but pursues a broader notion of justice. As a young Scotland Yard whiz-kid, he tries to unravel a series of murders and disappearances tied somehow to former German scientists and the American military.
The downside is-and I give nothing away by saying this-that too many central figures in the story are connected to Troy's personal life. One victim lives above his closest police friend, another is known to his uncle (who just happens to be a scientist working in military research), another central player is known to him from childhood, and another important character has a past history with Troy as well. Not to mention the climax, in which Troy's well connected brother plays a key role. It gets to be rather a lot to ignore, and the worst part is, there isn't really a need for all those connections to be there!
Fortunately, Lawton provides ample detail and atmosphere to keep everything enjoyable. His portrait of the tough conditions in wartime London, and the privileged place of the American military there is striking. Food rationing, bombing raids, dense fog, rubble-strewn streets, tough East End children, it's all highly evocative. Similarly, he provides a picture of England's simmering domestic political situation that will come as a surprise to many American readers. Every character springs to life under Lawton's pen, from Troy's keen subordinate, to his canny superior, to a hooker with a heart of gold, and bluff American officers. My own favorite is the cross-cursing Polish forensics expert.
Coincidences aside, the book is exceedingly well-written, and it's shame Lawton isn't better known in the US. A second Troy book, Old Flames, is set in 1956, a the third, A Little White Death, in 1963-neither of these had yet been published in US.
