George Manville Fenn (January 3, 1831, Pimlico - August 26, 1909, Isleworth) was a British writer.
He worked as a teacher in Lincolnshire, until he became printer, editor and publisher of various magazines. He had two sons and six daughters with his wife Susanna Leake, whom he had married in 1855.
He was editor and proprietor of Once a Week from 1873 until its demise in 1879 and then was entirely engaged in writing fiction. Most of his work consists of adventure stories for young readers, featuring Explorers, Smugglers, young Adventurers and Seamen. His adult novels offer critical social commentary on Victorian England, especially reconsidering economic questions.

Excerpt
“I hate you, sir, with all my heart, and you force me to say it. This is a cruel outrage. What have I done that you should dare to treat me so? Is there no one to help me? Bruno! Bruno!”
There was a short yelp, a sound as of a dog leaping to the floor, the rattle of nails in the hall, and a plump up against the door, accompanied by an impatient bark.
Saul Harrington, a good-looking man of five-and-thirty, started, and involuntarily loosed his hold of his captive, just as there was a sharp peal of a bell, and the slight, dark-eyed, trembling girl he had held in his arms slipped away, darted to the door of the sombre-looking dining-room, threw it open, and ran out, just as a great black Gordon-setter bounded in, set up the frill of hair about his neck, and uttered a low fierce growl, as he stood glaring at the occupant of the room.
