Bernie Gunther novel I read (Prague Fatale, see below), I can happily say that this, despite the horrible title, is one of the very best. Written in 2006, it was Kerr's return to Bernie after 15 years, and leads straight into its successor, A Quiet Flame, which I really rated.
The plotting is brilliant, the theme (nobody is who they seem) maintained throughout, and there is the essential element of extreme jeopardy for our hero. It's set in 1949 and finds Bernie running a hotel overlooking the Dachau concentration camp. He is hooked in to the conspiracy by, as usual, an attractive woman and the story spirals out from there. I certainly didn't see any of the twists coming.
There is also a long prologue set in Berlin and Jerusalem in 1937. I kept wondering how this was relevant. But then, brilliantly, it was.
