Sorry, pinched the title from Jonathan Meades's incisive introduction to this James Curtis novel originally published in 1938. Shorty Mathews has just been released from Pentonville when he stumbles on the body of a murdered prostitute. Fearing his innocence will not be believed he sticks out his thumb and heads north with police in hot pursuit. Meanwhile the real killer is left to his own sinister devices. The Great North Road is the doorway to a world of "coal gas and swill, soot and smuts, bleach and carbolic, drains and lard, Woodbines and belching tea urns."
Fantastic read, much more than a period crime/detective thriller. Forensic use of the vernacular and believable characters portray the alternative (but more likely accurate) England of the period than the one presented by the cinema.
