Roy Aubrey Kelvin Heath (13 August 1926 – 14 May 2008) was a Guyanese writer who settled in the UK, where he lived for five decades, working as a schoolteacher as well as writing. His 1978 novel The Murderer won the Guardian Fiction Prize. He went on to become more noted for his "Georgetown Trilogy" of novels (also published in an omnibus volume as The Armstrong Trilogy, 1994), consisting of From the Heat of the Day (1979), One Generation (1980), and Genetha (1981). Heath said that his writing was "intended to be a dramatic chronicle of twentieth-century Guyana". His work has been described as "marked by comprehensive social observation, penetrating psychological analysis, and vigorous, picaresque action."
