In this scholarly but lively survey of British crime films from the 1940s to the present day, Forshaw tracks down the ways in which the genre has offered "keen insights into the society of the day". Films such as Robert Hamer's It Always Rains on Sunday (1947) present an "unvarnished picture of crime and lives lived in quiet desperation", while the more recent Kidulthood (2005) by Noel Clarke shows that "alienated, disenfranchised youth" remains as central to the genre as in the 50s. From police corruption, dealt with in David Greene's The Strange Affair (1968), to paedophilia  the subject of Cyril Frankel's Never Take Sweets from a Stranger (1960)  crime films have consistently tackled subjects that mainstream film-makers have avoided: it is, argues Forshaw, "the cinema of the unacceptable". He considers class divisions, sexual taboos, censorship, corporate crime and violence, as well as the "grimly urban" settings of many of the films, such as Newcastle in Get Carter (1971). He proves himself to be an expert guide.
