The Knight's Cross Signal Problem

First published in 1914, The Knight's Cross Signal Problem is among the finest cases of Max Carrados, the sightless investigator whose heightened senses and formidable intellect made him one of the most original sleuths of the era. Its author, Ernest Bramah, saw his tales printed in The Strand Magazine alongside – and on occasion outselling – the Sherlock Holmes stories of Arthur Conan Doyle. Here Carrados turns his attention to a suspicious crash on the line, unravelling a scheme of ingenious cruelty.
