The daughter of a military father, Catherine was born in Germany and lived most of the first 14 years of her life abroad. She spent her school years devouring everything her school library offered.

Her favourite books were romance and mysteries. Her love for the Nancy Drew books led Catherine to check out every mystery story she could find. She soon found Agatha Christie, who quickly became Catherine's favourite author.

Catherine writes cosy mysteries that take place in the English countryside. Her extremely popular Tommy & Evelyn Christie mysteries are set in 1920s North Yorkshire. Her new series, the Martha Miller cosy mysteries, are set in the years following the Second World War in Berkshire.

​​​​​​​Catherine lives in northeast England with her two spoiled dogs who have no idea they are not human!
