Guilherme de Melo (born 1931 in Lourenço Marques, Portuguese Mozambique; died in Lisbon, 29 June 2013) was a Portuguese journalist, novelist, and activist. Melo lived through the protracted war of independence in the Portuguese colony of Mozambique in the 1960s and 1970s. Openly gay himself, Melo's novel "The Shadow of the Days" ("A Sombra dos Dias") is an account of growing up gay in the privileged environment of a white family in colonial Mozambique before the outbreak of war and of being openly gay against the background of an increasingly bitter anti-colonial war. After the Carnation Revolution and the independence of Mozambique in 1975, Melo went to Portugal.
