Either way, Professor March was struggling with it. The spell was in a very proper and precise Medieval Dutch that evidently wasn’t his forte. It occurred to Quentin that it might be nice if he screwed it up. He hadn’t particularly enjoyed being called out on technical minutiae this early in the morning. He would play a tiny prank.

Brakebills classrooms were proofed against most forms of mischief, but it was well known that the podium was any teacher’s Achilles’ heel. You couldn’t do much to it, but the wards on it weren’t quite ironclad, and with a lot of effort and some body English you could get it to rock back and forth a little. Maybe that would be enough to throw Professor March (the students called him “Death” March) off his game. Quentin made a few small gestures under his desk, between his knees. The podium stirred, as if it were stretching a kink in its back, then became inert again. Success.

March was reeling off some extra Old High Dutch. His attention flicked down at the podium as he felt it move, and he hesitated but recovered his concentration and forged ahead. It was either that or start the whole spell over.

Quentin was disappointed. But Infallible Alice leaned over.

“Idiot,” she whispered. “He dropped the second syllable. He should have said—”

Just then, for an instant, the film of reality slipped off the spokes of its projector. Everything went completely askew and then righted itself again as if nothing had happened. Except that, like a continuity error in a movie, there was now a man standing behind Professor March.

He was a small man, conservatively dressed in a neat gray English suit and a maroon club tie that was fixed in place with a silver crescent-moon pin. Professor March, who was still talking, didn’t seem to realize he was there—the man looked out at the Third Years archly, conspiratorially, as if they were sharing a joke at the teacher’s expense. There was something odd about the man’s appearance—Quentin couldn’t seem to make out his face. For a second he couldn’t figure out why, and then he realized it was because there was a small leafy branch in front of it that partially obscured his features. The branch came from nowhere. It was attached to nothing. It just hung there in front of the man’s face.

Then Professor March stopped speaking and froze in place.
