Just in case you thought I only read books that turn out to be good:
Raymond Postgate, "Somebody At the Door"
Originally published 1943
Reprint in the British Library Crime Classics series2017
I have been a fan of the British Library Crime Classic series from its inception; I've bought and read with pleasure a large number of them (20+, I'm estimating). Bit I have begun to wonder whether the series is running out of high quality material.
The last half dozen or so that I've read have been pedestrian at best, and the one I just finished--Raymond Postgate's "Somebody At the Door" (originally published in 1943)--was at best mediocre (starting with the title which actually doesn't even make sense, given the story). There is a 70+ page section (30% of the book) that provides unnecessary--irrelevant, really--backstory, for example. And the ending seems tacked on just to come up with a conclusion. One oft he least rewarding books I have ever read.
