Sir Arthur Ignatius Conan Doyle was a British writer best known for his detective fiction featuring the character Sherlock Holmes. Doyle was a prolific writer; his non-Sherlockian works include fantasy and science fiction stories about Professor Challenger and humorous stories about the Napoleonic soldier Brigadier Gerard, as well as plays, romances, poetry, non-fiction and historical novels. Stephanie was born in England before emigrating to Australia – and later New Zealand – with her family, where she trained as a nurse. Whilst back in England on holiday, she met and married her husband, had a daughter and settled down. Stephanie's lifelong interest in writing became more serious when her first children’s book, Avalanche, was published in the 1980s. Since then, she has had around forty children's books published, and has also published an historical novella for adults.
