Jeffery Farnol (1878–1952), born John Jeffery Farnol, was an English novelist best known for historical romances and adventure fiction. He became one of the most widely read writers of romantic historical fiction in the early twentieth century, achieving particular success with The Broad Highway in 1910 and The Amateur Gentleman in 1913. Farnol specialised in an idealised England of country roads, coaching inns, highwaymen, prize-fighters, sailors and gentlemen adventurers, drawing particularly on the Georgian and Regency periods. His fiction combines vigorous action with courtship, humour and an affection for deliberately archaic speech, creating a highly distinctive version of the historical adventure novel.
Farnol wrote prolifically across more than four decades. The Broad Highway and its related novels follow characters caught between social rank, personal honour and romantic adventure, while Black Bartlemy’s Treasure and Martin Conisby’s Vengeance turn to piracy, lost treasure and revenge. His Jasper Shrig novels, beginning with Peregrine’s Progress, combine historical adventure with crime and mystery, while books such as The Geste of Duke Jocelyn, John O’ the Green, The King Liveth and Beltane the Smith range more widely across medieval and early-modern settings. Although his popularity diminished after his death, Farnol remains representative of the richly romantic tradition of British historical fiction that flourished between the late Victorian adventure novel and the more research-driven historical fiction of the later twentieth century.
