Night Darkens the Street is a 1947 crime novel by the British writer Arthur La Bern. The title is taken from a line of Paradise Lost by John Milton. It is also known as Night Darkens the Streets. It was inspired by the Cleft chin murder of 1944.
Glen Rawlins, a teenager with ambitions, runs away from her drab Pimlico home and becomes mixed up with the shady but seemingly glamorous world of London's West End nightclubs. Attractive but starry-eyed and naïve, she ends up falling in with a deserter from the American army who draws her into murder.
In 1948 it was adapted into the British film noir Good-Time Girl directed by David MacDonald and starring Jean Kent, Dennis Price and Herbert Lom.
