This is a really great story. Joe is an amateur magician, he and his (not very), psychic dog, Bingo, go to spend a week at The Centre For Botanical Research. On his very first night Joe hears a terrible wail from the garden. What can it be? Molly and Joe find there is a creature trapped in the old, disused swimming pool and that the new scientists are doing horrid things to it. They have to defeat the scientists and save the monster. I loved this book, enjoyed every moment. I urge you to read it!
