Although somewhat neglected now, at the height of his fame Ernest Bramahs mystery tales appeared alongside Sir Arthur Conan Doyles Sherlock Holmes stories in the Strand Magazine, even occasionally outselling them. First published in 1913, The Knights Cross Signal Problem was one of his popular tales. Many crime and detective stories, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
