Robin was born in California and grew up in an Oxford college, across the road from the house where Alice in Wonderland lived. 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). Robin is now a full-time author, and her books, The Murder Most Unladylike Mysteries and The Guggenheim Mystery, are both award-winning and bestselling. She lives in Oxford.
