Marianne Macdonald was born in the lumber town of Kenora, Northern Ontario, and grew up in Winnipeg and Montreal.
Her first children’s book was published when she was 16. She took her BA at McGill University, then went to Oxford for graduate studies in English. For thirty years she pretended to be an academic acquiring various degrees and teaching at various universities in Canada and England. She left teaching early in order to return to her writing.
Since 1996 she has published a series of novels in which Dido Hoare, thirty-something London single mother and antiquarian book shop owner, is involved in murder and mayhem thanks to her itch of curiosity and an inability to back down even when she knows she should.
