The last two I was shaky on but the first four I flat out went and looked up. I had a much better vocabulary when I was in school. Somehow Dorothy Sayers and Josephine Tey go together well. Some research shows that they were born three years apart and Sayers only had a couple of years head start on the mystery novel writing game, I wonder why I always assumed Tey was of a later era? Maybe Lord Peter will just never be a modern character to me. It may also be his trappings of old-fashioned English aristocracy. There is nothing old-fashioned about Inspector Grant, and I am almost as fond of him as I am of Lord Peter.
Any other fun brainy mystery-writing ladies I should be reading? Also, is it interesting or just a sign of their times that both of these ladies had male protagonists to solve their mysteries? Barring Miss Climpson, of course.
