The Bookwoman's Last Fling by John Dunning

The Bookwoman's Last Fling is another book in the Cliff Janeaway mystery series. In this book, Cliff is trying to solve a decades old mysterious death, as well as track down a possible book thief. Most of the action takes place in and around horse-racing tracks, when Cliff goes undercover to find out more about the mystery from the past. Some interesting characters are introduced and there are interesting discussions of juvenalia and bibliomania, but this is not one of the strongest mysteries in the series.
