In 2006 I illustrated a book called ‘The Poison Diaries” for the Duchess of Northumberland. It was one of the most enjoyable projects that I have worked on. The Duchess is an expert on poisonous plants and has built a poison garden in the grounds of Alnwick Castle, where she lives. Open to the public, the garden also includes an epic water feature and an enormous tree house. It is a spectacular place to visit and has become the largest tourist attraction in the north east of England.
