"It must be a magic oath," said Maggie, examining the dead body on the floor. After receiving a few clues regarding the black witches' plan, I called Maggie to see if she knew anything about this matter. Though she'd complained about being called right before her beauty sleep, the mention of money made her come rushing.
"A magic oath?"
"It is an oath made of magic," she said as she knelt down, marveling at the organs that had poured out of Mr. Wickham's body. "Once made, one is unable to break the oath since the magic will prevent them from doing so. In this case, it looked like this man had taken an oath to maintain a secret, so when he tried to break the oath, the magic stopped him by making him puke ceaselessly to death."
Was this the reason why Mr. Wickham was so careful with his words? But it didn't look like he knew anything about the oath. It was obvious that he was as surprised as I was when he suddenly puked out of nowhere.
