They Do It With Mirrors

Agatha Christie

HarperCollins Publishers. First published 1952

Another murder set in a rich country house, with a fairly large cast of conventional AC characters. The owner of the house also runs an institution to rehabilitate juvenile delinquents on the same grounds, and that leads to some tensions that are exploited to lend weight to the story. Once again, I could guess, fairly early on, who the murderer is. So that makes it four times in the last four AC books. I hope that at least the next couple are less predictable. 

The narrative is full of British right-wing views and casual racism, which are unacceptable now, six decades later. But again, I should not take 'a spade to a souffle'.
