Murder and the Married Virgin, by Brett Halliday (HC, 1948, $2, which is 1/3 the current internet price, with yellowed pages.)
OK, so I read this book only because of the title. The book is a hoot, telling the story of a Norwegian servant who is found dead, apparently of suicide, which could not be true because she was" a virgin in mind, soul, and body." (Also, she was Norwegian.)
Read this story and find out how an emerald necklace and an escaped convict connect to her "suicide". Look for it in the mystery section. (Avail. 11/29)
