Harry loves the Hideout that he built with his Grandad. In it he keeps the very special book that Grandad gave him to help him to learn about the Person who made the whole world. But it's not just any book - it's a portal to Bible times.
In Mud, Harry has a great time making pots from the clay that he finds in his garden. Then, after travelling back to Bible times, Harry discovers how Jesus used mud made to make a blind man see. In Minibeasts, Harry is distraught when he finds Walter, a pet woodlouse, near death. His excitement when it revives is reflected in Mary and Martha, as Harry is transported to Bible times and sees Jesus raising Lazarus from the dead.
