Irwin was born in Highgate Hill, London, to Andrew Clarke Irwin (a native of Perth, Western Australia, d. 1902) and Anna Julia Irwin (née Baker, d. 1899), the daughter of Col. George Baker of the 16th (Queens) Lancers. She was brought up by her uncle S. T. Irwin (Sidney Thomas Irwin), a master of Classics at Clifton College, then a boys' school. Irwin attended the nearby Clifton High School, a girls' school, in Bristol, after her parents died. She was educated at Clifton and at Oxford University, where she took a degree in English. She began writing books and short stories in the early 1920s. In 1929 she married children's author and illustrator John Robert Monsell, who created the covers for some of her books.
Her novels were esteemed for the accuracy of their historical research, and she became a noted authority on the Elizabethan and early Stuart era. One of her novels, Young Bess about the early years of Queen Elizabeth I, was made into a film of the same title starring Jean Simmons.
Irwin wrote several ghost stories (including "The Book" and "The Earlier Service"). Irwin also wrote two fantasy novels: Still She Wished For Company is about a magical timeslip, while These Mortals is an adult fairy-tale about a wizard's daughter.
