Plum got up at eight the next morning, late by her standards, but instead of rejuvenating her brain the extra sleep had just made it all muzzy. It had smeared all those clear thoughts she was supposed to be having all over the inside of her skull. Her depressive tendency, the flip side of her manic streak, was stirring. Why were they even doing this? it wanted to know. What a waste of time, of effort. Of pencils. Plum needed to get moving, but she was having trouble attaching meanings to things; the meanings kept peeling off like old stickers.

As a Finn who’d finished her required coursework Plum was taking all seminars that semester, and her first class was a colloquium on period magic, fifteenth-century Continental to be specific—lots of elemental stuff and weird divination techniques and Johannes Hartlieb. Holly—a fellow Leaguer, moon-faced and pretty, except for one ear which was covered in a port-wine birthmark—sat opposite her across the table, and such was Plum’s smeary state that Holly had to touch her sharp little nose meaningfully, twice, before Plum remembered that that was the signal that Stages One and Two of the plan had been completed successfully.

Stage One: “Crude but Effective.” A few hours earlier Chelsea’s boyfriend would have smuggled her into the Boys’ Tower under pretense of a predawn sex date. Nature having taken its course, Chelsea would have gone to Wharton’s door, pressed her back against it, touched her fingers to her temples in a gesture so habitual that she no longer knew she did it, rolled her eyes back into her head and entered his room in a wispy, silvery, astral state. Chelsea did it all the time—astral projection was her discipline—but it was still one of the most flat-out beautiful pieces of magic Plum had ever seen. Chelsea tossed his room for the pencil case, found it and grasped it with both of her barely substantial hands. She couldn’t get the pencil case out of the room that way, but she didn’t have to. All she had to do was lift it up to where it could be seen in the window.

Wharton himself might or might not have been watching this, depending on whether or not he was asleep, but it mattered not. Let him see.

Because once Chelsea got the case over by the window, earnest Lucy had line of sight to it from a window in an empty lecture hall in the wing opposite Wharton’s room, which meant she could teleport the pencil case in that direction, from inside Wharton’s room to midair outside it. Three feet was about as far as she could jump it, but that was plenty. Thank God for people with actual useful disciplines.
