I have discovered a great reference book on this subject. It is by Tasha Mackler, MURDER...BY CATEGORY: A SUBJECT GUIDE TO MYSTERY FICTION (Metuchen, NJ: Scarecrow Press, 1991). Some of the subjects covered include; libraries, bookstores, art and artists (but no museums), anthropology and archaeology, jewels, Indians, academics, antiques, cats, historical, witches, and manuscripts.
