I had not read this Christie before, turns out I didn’t miss much
3 stars
Entertaining, but appalling stereotyping even by 1920s standards. All the minor villains are almost comically unoriginal, a bunch of foreign communists with low brows, small eyes and harsh accents. The main characters are more sympathetic, but only slightly more interesting, especially in the first half of the book. But points added back on for the locked room mystery, I really liked that.
