Everybody likes to think they're honest - but are they? It's all very well saying that you don't tell lies but what happens when you can't tell lies (even the little white lies you tell to be nice to people)? What happens when you have no choice in the matter and have to be completely honest no matter what? Rummaging around in her Uncle Harry's sea chest, Lucy Roberts finds an old parchment containing the curse of Mad Jack Halloran (a pirate from the 1800's). Unfortunately, for Lucy, the curse causes its victims to become totally honest. Can Lucy survive until she finds the counter spell that breaks the curse - or will the curse get her into ever-increasing amounts of trouble? Written for 10/11 year olds, The Curse of Mad Jack Halloran explores the subject of honesty in a humorous manner.
