Mercifully, Tom’s thoughts changed away from his own impending doom. Albus Dumbledore, Grindelwald had explained to him, was the Deputy Headmaster of Hogwarts. Hogwarts was the school of magic that Tom should have attended from age eleven, but Dumbledore had custody of the list of young witches and wizards and apparently had chosen not to invite Tom. Dumbledore was therefore responsible for everything that had happened to Tom since then, and Tom was determined to have his revenge.
