A Quiet Flame by Philip Kerr
4.0
Bernie Gunther may be the perfect noir detective. WWI veteran, honest Weimar cop, forced into PI work by the Nazi seizure of power, conscripted into WWII, mistakenly pursued as a war criminal after unmasking some real ones, and currently on the lam in Argentina, where he's been blackmailed into looking into something distasteful by the Perons. This is an excellent entry in a series at the top of my "honest men in corrupt regimes" collection of mystery novels.
