James Sallis has a modus operandi: never to waste a word. Sarah Jane (No Exit Press, £8.99) follows this stricture well, using a sparse yet poetic style to tell the story of a woman born on the wrong side of town to bad parents, who wanders from one lowly job to another, one unsavoury man to another, one trouble to another, living a life of chaos, until, led by some curiously twisted route, she takes a chance and decides to join the police, working small cases in a small town.
