It's hard to be a sixteen year old girl in 1910. Charlotte is all too familiar with this, being the only child of the Duke and Duchess of Cambridge. When her Uncle and Aunt, Lord Wright and Lady Wright, invite her and her same-aged maid Anne to stay over at their country estate with them, she's only too glad to get away from home. The catch? Her parents are to come too. Charlotte spends the beginning of her stay being with Anne and her eighteen year old cousin Benedict, when a most prestigious guest comes from France: the Duke of Avaray, along with his eighteen year old son Dominique, known in England as Dominic. Charlotte and Dominic clash on several occasions, but they find they need to join forces after the Duke of Avaray is murdered with Cyanide - and Geoffrey, the Butler that has taken care of Charlotte and Benedict since they were children is blamed. Can they solve the mystery, and will justice prevail?
