Gaslight and Others is a term used to refer to a group of plays written by the British playwright Patrick Hamilton in the 1930s and 1940s. The term is derived from the title of Hamilton's 1938 play Gaslight, which was later adapted into a film in 1940. The other plays in the group include Rope (1929), Angel Street (1938), and The Duke in Darkness (1943). The term ERAS refers to the period of time during which these plays were written, which is known as the Edwardian era.
