A very good mystery set in post-WWI England. I love books set before the rise of modern forensic science, as it seems to leave more of the mystery in the mystery. Inspector Routledge is a compelling character - just returned from the horrors of the trenches himself, and profoundly changed by the horrors he experienced there. He is battling to find out who he is now, and whether he can still muster the mental strength to find a murderer. I look forward to reading more of this series.
