THere's a really good book of quotations by Jane E. Horning called THE MYSTERY LOVER'S BOOK OF QUOTATIONS. It's from Mysterious Press, 1998 in hardcover then there was a trade paperback.
This is a treasure trove of fun quotes for mystery fans. It's arranged alphabetically by author but there's an index in the back so you can look up quotes by topic. This is one of my favorite dipping-into-before-sleeping reads. There should be an updated edition!
