Thirteen cases which have never had conclusive endings under investigation. Evidence and findings presented and questioned concerning Dolly Reynolds, Collings, Leslie, Cookson, Daff, Benders, Wardlaw-Sheed, Case, Moench-Ridley-Weinstein, Townsend, Carman, Stewart, and Mangrum. Ranges from mid-1900's to 1931, and the U. S. is the background except for one in Canada and one in England. Several of the later ones will be remembered, but there is no rehashing of cases too familiar to the public. The time range gives an interesting contrast in methods of detection and police work used. Plus sale in the mystery department and a good bee for those who like true cases of crime.
