His father was Arthur Hughes, a civil servant, and his mother was Louisa Grace Warren who had been brought up in the West Indies in Jamaica.
Hughes's short play The Sisters' Tragedy was being staged in the West End of London at the Royal Court Theatre by 1922.
Dylan Thomas stayed with Hughes and wrote his book Portrait of the Artist as a Young Dog whilst living at Castle House.
In 1938, he wrote an allegorical novel, In Hazard, based on the true story of the S.S. Phemius who was caught in the 1932 Cuba hurricane for four days during its maximum intensity.
In these, he describes the course of European history from the 1920s through World War II, including real characters and events—such as Hitler's escape after the abortive Munich putsch—as well as fictional.
Hughes also ghost-wrote The Story of the Lyric Theatre, Hammersmith (1925) for Nigel Playfair,[10] and collaborated with J. D. Scott on an official government publication, The Administration of War Production (1955).
