Christianna Brand was born in 1907 in Malaya and spent her early years in India. She had a number of different occupations, including model, dancer, shop assistant and governess.

Her first novel, Death in High Heels, was published in 1941. A year later her best-loved series character, Inspector Cockrill of the Kent County Police, made his debut in Heads You Lose. He would feature in a total of seven of her detective novels. Green for Danger is Brand's most famous novel and considered by many to be her masterpiece. H.R.F. Keating described the novel as 'the last golden crown of the Golden Age detective story'. The novel was adapted for the big screen in 1946 starring Alastair Sim as the Inspector.

Christianna Brand's most appealing characteristic as a writer was her ability to blend complex and intriguing plots with a lively sense of humour conveyed both through character and dialogue. Brand herself admitted: 'I write for no reason more pretentious than simply to entertain.'

The character of Nurse Matilda was invented by Christianna's family, and when Christianna was a little girl, her grandmother used to delight her with stories about the magic nanny.  The artist, Edward Ardizzone, who later illustrated the stories, was Christianna's first cousin and he also heard the stories from their grandmother.

Christianna Brand was married to her husband Roland for nearly fifty years. She died in 1988.
