Here's something I've never heard before, and I just figured it out.
The Phantom (Erik) went to the masquerade ball as the red death. The red death is a short story by Edgar Alan Poe. If he dressed up like that in the masquerade ball, it means he has been reading Edgar Alan Poe's stories. So we can conclude to the fact that he liked this kind of stories.
