Here is another thrilling novel related by that ingenious mystery writer Harry Stephen Keeler in collaboration with his wife Hazel Goodwin. The story fairly bristles with excitement and suspense throughout. Why did the murderer of Nels Pederson amputate his legs and sew them back with silver wire, transposed? How was a book on cats the key to an escape from prison? Why was a literary manuscript sent to Rudolph Uberhulf, a convict who could scarcely read or write? These, and many similar problems make this an all-absorbing novel.
