Capítulo 715: Chapter 525 Mysterious Disappearance_2

Not to mention that the bizarre warning letter didn't even have a name written on it, so many people didn't associate this with it at first.

However, after a week, another warning letter appeared on the bulletin board, followed by another student not showing up for school the next day.

It was then that everyone realized that something was awry, and some people in the Math department were on edge. In fact, within the Royal Academy now, some students were privately discussing a story—someone dead was masquerading as a living person in their school, issuing warning letters and then murdering people.

As Mary was a History department student and was either training with Lorena or busy with classes and visiting Shirley each day, she didn't pay much attention to these rumors. It wasn't until last week when she was having tea with Asherica, noticing her troubled expression, that Mary asked her about what had happened.
