Hildegarde Withers was one of the first female schoolmarm detectives to appear in mystery. From her appearance in The Penguin Pool Murder in 1931, the teacher caught the attention of the American reading public. In the years that followed, she appeared in a number of films, a humorous series of collaborative mysteries with the Chicago lawyer, John J. Malone, and of course - short stories. Multiple collections of Stuart Palmer's works exist, including Crippen & Landru's Hildegarde Withers: Uncollected Riddles in 2002. Now nearly two decades later, another Crippen & Landru collection Hildegarde Withers: Final Riddles? As more newspapers, magazines, and documents are put online, we have been able to locate more works by Palmer, with possibly more to come in the future. Hence, the less than certain title . This collection contains stories about Hildegarde Withers, Howie Rook, Sherlockiana, and other characters as well.
