When the circus is in Castle Key, a trapeze artist is injured in a fall, Scott, Jack and Emily find themselves drawn into a maze of secrets and lies. Why are there suddenly so many accidents? Is a cursed jewel really to blame? And will Drift the dog ever be reunited with his new love, Mimi the circus poodle? I love this book, and I recommend it to anybody that is reading this. Some people say that the Helen Moss, Adventure Island series is like Famous Five, except more modern.
