I knew right then and there that I had to act to protect us. Petunia wouldn’t have hesitated one moment to shout my name aloud. If she did, then we would be done for. There is no way we could have erased that. Even if we obliviated every hostage, we would never have the time to erase the recordings. Then, it would only be a question of time before my name was published everywhere in the press.
