Chapter 119

By noon, Harry opened the Marauder’s Map and saw Quirrell positioned unmistakably at the end of the fourth floor.

Harry figured Quirrell must have already entered the final chamber. He had likely been stuck in front of the Mirror of Erised all morning, scratching his head and getting nowhere.

Originally, Harry hadn’t planned on interfering with Voldemort. After all, this was his only chance to trick Dumbledore and steal the Philosopher’s Stone. If he failed now, it would be his last opportunity. Once Dumbledore returned, his sharp instincts would surely lead him to suspect Quirrell.
