The Hand in the Dark by Arthur J. Rees — Read

It was the morning after the murder, and five men were seated in the moat-house library. One of them attracted instant attention by reason of his overpowering personality. He was a giant in stature and build, with a massive head, a large red face from which a pair of little bloodshot eyes stared out truculently, and a bull neck which was several shades deeper in colour than his face. He was Superintendent Merrington, a noted executive officer of New Scotland Yard, whose handling of the most important spy case tried in London during the war had brought forth from a gracious sovereign the inevitable Order of the British Empire. Merrington was known as a detective in every capital in Europe, and because of his wide knowledge of European criminals had more than once acted as the bodyguard of Royalty on continental tours, and had received from Royal hands the diamond pin which now adorned the spotted silk tie encircling his fat purple neck.

The famous detective's outlook on life was cynical and coarse. The cynicism was the natural outcome of his profession; the coarseness was his heritage by birth, as his sensual mouth, blubber lips, thick nose, and bull-neck attested. It was a strange freak of Fate which had made him the guardian of the morals of society and the upholder of law and order in a modern civilized community. By temperament and disposition he belonged to the full-blooded type of humanity which found its best exemplars in the early Muscovite Czars, and, if Fate had so willed it, would have revelled in similar pursuits of vice, oppression, and torture. As Fate had ironically made a police official of him, he had to content himself with letting off the superfluous steam of his tremendous temperament by oppressing the criminal classes, and he had performed that duty so thoroughly that before he became the travelling companion of kings his name had been a terror to the underworld of London, who feared and detested his ferocity, his unscrupulous methods of dealing with them, and his wide knowledge of their class.
