Will arrived in Germany with questions on his mind.
Hobert had indeed thrown a party, inviting plenty of his friends in Germany and a crowd of young women. Will, however, had no interest in joining them.
Instead, Will spent the night in his room studying the Hour-Reversal Charm. The battered booklet he had found in the Black family home was the manuscript of a scholarly wizard from the family. The wizard had spent years researching the spell, with mixed results.
