Son of Raymond J. and Miriam Hensher,[2] his father a bank manager and composer[3][4] and his mother a university librarian,[5][6] Hensher was born in South London,[where?], although he spent the majority of his childhood and adolescence in Sheffield, attending Tapton School.

The Bedroom of the Mister's Wife (1999) brings together 14 of his short stories, including "Dead Languages", which A. S. Byatt selected for her Oxford Book of English Short Stories (1998), making Hensher the youngest author included in the anthology.[9]

Hensher's early works of fiction were characterized as having an "ironic, knowing distance from their characters" and "icily precise skewerings of pretension and hypocrisy".[8] His historical novel The Mulberry Empire "echoes with the rhythm and language of folk tales" while "play[ing] games" with narrative forms.[8]
