James was born in Oxford, the daughter of Sidney James, a tax inspector, and educated at the British School in Ludlow and Cambridge High School for Girls. She had to leave school at the age of sixteen to work because her family did not have much money and her father did not believe in higher education for girls. She worked in a tax office for three years and later found a job as an assistant stage manager for a theatre group. In 1941, she married Ernest Connor Bantry White, an army doctor. They had two daughters, Clare and Jane. When White returned from World War II, he was experiencing mental illness, and James was forced to provide for the whole family until her husband's death in 1964. With her husband in a psychiatric institution and their daughters being mostly cared for by his parents, James studied hospital administration and from 1949 to 1968 worked for a hospital board in London. She began writing in the mid-1950s. Her first novel, Cover Her Face, featuring the investigator and poet Adam Dalgliesh of New Scotland Yard, named after a teacher at Cambridge High School, was published in 1962. Many of James's mystery novels take place against the backdrop of UK bureaucracies, such as the criminal justice system and the National Health Service, in which she worked for decades starting in the 1940s. Two years after the publication of Cover Her Face, James's husband died, and she took a position as a civil servant within the criminal section of the Home Office. She worked in government service until her retirement in 1979.
My Opinion: I know I have read some of her books but don't remember any specifics. Suggest you give her a try.
