Harry kept looking behind him. The old feeling that he was being watched was upon him. The maze was growing darker with every passing minute as the sky overhead deepened to navy. He reached a second fork.

“Point Me,” he whispered to his wand, holding it flat in his palm.

The wand spun around once and pointed toward his right, into solid hedge. That way was north, and he knew that he needed to go northwest for the center of the maze. The best he could do was to take the left fork and go right again as soon as possible.

The path ahead was empty too, and when Harry reached a right turn and took it, he again found his way unblocked. Harry didn’t know why, but the lack of obstacles was unnerving him. Surely he should have met something by now? It felt as though the maze were luring him into a false sense of security. Then he heard movement right behind him. He held out his wand, ready to attack, but its beam fell only upon Cedric, who had just hurried out of a path on the right-hand side. Cedric looked severely shaken. The sleeve of his robe was smoking.

“Hagrid’s Blast-Ended Skrewts!” he hissed. “They’re enormous—I only just got away!”

He shook his head and dived out of sight, along another path. Keen to put plenty of distance between himself and the skrewts, Harry hurried off again. Then, as he turned a corner, he saw . . . a dementor gliding toward him. Twelve feet tall, its face hidden by its hood, its rotting, scabbed hands outstretched, it advanced, sensing its way blindly toward him. Harry could hear its rattling breath; he felt clammy coldness stealing over him, but knew what he had to do . . .

He summoned the happiest thought he could, concentrated with all his might on the thought of getting out of the maze and celebrating with Ron and Hermione, raised his wand, and cried, “Expecto Patronum!”

A silver stag erupted from the end of Harry’s wand and galloped toward the dementor, which fell back and tripped over the hem of its robes . . . Harry had never seen a dementor stumble.

“Hang on!” he shouted, advancing in the wake of his silver Patronus. “You’re a boggart! Riddikulus!”

There was a loud crack, and the shape-shifter exploded in a wisp of smoke. The silver stag faded from sight. Harry wished it could have stayed, he could have used some company . . . but he moved on, quickly and quietly as possible, listening hard, his wand held high once more.

Left . . . right . . . left again . . . Twice he found himself facing dead ends. He did the Four-Point Spell again and found that he was going too far east. He turned back, took a right turn, and saw an odd golden mist floating ahead of him.
