Malcolm Sage, Detective (PDF)
Herbert George Jenkins' popular detective, Malcolm Sage, drops neatly into the same general category as Conan Doyle's Sherlock Holmes, if physically somewhat less attractive. Sage is bald, wear gold rimmed glasses, and has an oddly conical head. And while apparently capable of putting up a good fight when necessary, he clearly prefers to let his brain do all the work. Some have even suggested Sage as a possible influence on Agatha Christie's Poirot.
Originally published in 1921, Malcolm Sage, Detective, is a collection of Jenkins short stories, which were first published in magazines shortly after the end of World War I. A few stories stand alone, but most were serialised over two or three issues, making this collection by far the easiest way to read them.
This edition has been carefully edited, with 54 new notes clarifying some now obscure details, and includes an Afterword touching on various points in the stories.
