Robin Stevens was born in California and grew up in an Oxford college. She spent her teenage years at Cheltenham Ladies' College, reading a lot of murder mysteries and hoping that she'd get the chance to do some detecting herself (she didn't).
She studied crime fiction at university, and then worked in children's publishing. She is now a full-time writer and the creater of the bestselling, award-winning Murder Most Unladylike series. Murder Most Unladylike was the bestselling middle-grade debut of 2014, winning the Waterstones Children's Book Prize for Younger Fiction and sparking a trend for middle-grade mysteries. Robin lives in London with her pet bearded dragon, Watson.
