Philip Kerr's 8th book in his Bernie Gunther series, "Prague Fatale" is a return to the five star writing after "Field Grey", his 7th book, that was good, not great. Kerr's novels are best tagged as historical mysteries, but with less emphasis on the "mysteries" and more on the "historical". Kerr does an excellent job in evoking both the times of Germany in the 1930's, 40's, and 50's as well places. Some of the action in the eight books happens in such far flung locals as Cuba, South America, and the US, but most occur in Germany, Russia, and, in this case, Bohemia. One of the flukes of the series is that Philip Kerr doesn't write them in chronological order, so Bernie Gunther's time-set in this book is in early 1940's Berlin and Prague, but earlier books have had him in post-WW2 adventures.
In "Prague", Bernie Gunther is back working for the Berlin police and is back at the "Alex", the main Berlin police station in the Alexanderplatz. He had been serving in the SD, in Russia and had taken part in killings of partisans. Kerr is somewhat murky about Gunther's political allegiances; he's not a Nazi-party member, but is a member of the SD. He doesn't like Hitler but has been coerced into serving in various German army positions. Gunther seems to twist his body - and the reader - into contortionist positions in his attempts to explain who he was to whom.
In Berlin, in the summer of 1941, Bernie Gunther is trying to track down a knife-wielding killer when he meets up with a "good-time girl", who he rescues from what appeared to be a rape-attack. They begin a relationship - Gunther is a long-time widower and the woman is a recent widow - and when Reinhard Heydrich taps Bernie Gunther to serve him in his new post in Prague, Gunther and the young woman move to Nazi-occupied Prague. Various murders ensue and Gunther is charged by Heydrich to solve the murders. Added to the murders is the ever-present threat by Czech nationalists to disrupt the German occupation of Bohemia and Moravia.
"Prague Fatale" is a fast-paced book in which the reader becomes as confused as Bernie Gunther. But the old Berlin "bull" figures things out and the ending is tidily tied up. Bernie lives another day - don't even think you can read this series "in order" - and Philip Kerr has written another excellent novel.
