The Middle of Things by Joseph Smith Fletcher
In the heart of London, John Ashton–the man from Australia–has been murdered. It seems clear that the motive was not robbery, and as he apparently had no acquaintances in town, the exposure of the murderer appears hopeless. Nevertheless, Mr. Fletcher accomplishes it in a story that keeps the reader in suspense until the very last word. This talented author has no rival to-day in ingenuity.
