Before she became a writer, Caroline Green was a journalist and Paddington Bear obsessive (although not necessarily in that order). She has written bestselling crime novels (writing as Cass Green) and award-winning fiction for teenagers.

Caroline lives in North London and teaches writing to both adults and children. There's a Dog in My Brain! is her first novel for younger children, in part inspired by the fact that she has an unusually good sense of smell (for a human).
