Charlie Bone and his Uncle Paton are visiting Charlie's old house while his parents are out whale watching (on their second honeymoon). While there he finds that his whole upstairs floor area was ripped up and they find that there were people inside the house earlier. When Charlie goes to Bloor's Academy he finds a new boy is there that he has to guide around. His name is Dagbert Endless because his last names are "as endless as the seas". Dagbert's endowment is to drown other people, controlling water. Dagbert has to be around Charlie all the time, so he starts to drive his friends away by insulting them. Later Charlie finds out that his great Aunt Venetia will marry a man who has two young children.
