The Sleuth of St. James's Square

Melville Davisson Post

> This volumes includes 16 mystery stories, each connected - if sometimes tangentially - to Sir Henry Marquis, head of the Criminal Investigation Department of Scotland Yard, who is called upon to solve some of the strangest and most puzzling cases in Britain. It starts with a locked-room mystery and ends in Scotland, at a house by a Loch where more is going on than meets the eye.
