My thanks (again!) to David Isaak for drawing my attention to this review in the Washington Post.
Some pull-out quotes:
R.N. Morris's lively, literate "The Gentle Axe"
"The Gentle Axe" is a deftly plotted, enjoyable literary thriller. It's not another "Crime and Punishment," but it's a novel that, once begun, you're likely to read all the way through.
I google trawled another review too. From a site called BookLoons. The reivewer there calls it a 'top-notch mystery'.
See you at The Rap Sheet!
