'It is a story told in the first person by a successful doctor who says about himself:– "Married to the daughter of a peer, Lord Carden of Ashdown Castle, and myself believed to be connected with another titled family, my practice is not unnaturally what would be called a fashionable one. I have a steadily increasing following among the best people in Society circles ... I am the youngest practitioner to have been admitted to the very exclusive Fellowship of the Royal College of Physicians.'' His origin was actually a lowly one, both his father and his mother once having been humble employees of his beautiful young wife's parents. And his father was hanged for murder! He has assumed a false identity, and, far worse, he has committed murder: he has killed the man—"a vile man, one of the vilest"—who long before gave false witness against his innocent father. His life's history, and the way in which he has got the better of Gilbert Larose—"the star detective of the Yard, the man who by-passed all lack of clues and worked on his imagination!"—are told in this novel in Mr. Gask's usual popular style.'
