I read this book about 13-Dec-2003. This is the first time I've read this book. The book is copyright 1973. This note was last modified Monday, 05-May-2014 22:30:20 PDT.
This is book 3 of the "Roderick Alleyn" series.
This note contains spoilers for the book.
No copyright date shown; earliest edition shown is 1973. The background feels very old, except for the popularity of communist organizations. I don't know England at all in this period—I didn't get there between 1967 to 1987.
A lovely setup, with a completely ridiculous number of people with means, motive, and opportunity for the murder. His wife, his discarded mistress (a nurse at the operation), his old friend the surgeon (who wants to marry the discarded mistress), another nurse who's a committed communist, and of course external enemies (communists, anarchists, etc.).
Murder in an operating theater, where everything is cleaned up and polished immediately afterwards, eliminating a lot of possible clues.
Of course, none them is the actual murderer.
