Enoc Huws is a classic novel by Daniel Owen, written in the Welsh language and first published in 1891. It has been adapted for stage and television (in an early 1974 TV adaptation, and later as Y Dreflan on S4C).
The story concerns the activities of the villainous Captain Trefor, and is set in the small town of Treflan, which appears in two earlier novels by the same author.
