My laboratory is in the subbasement under my basement apartment. It’s dark, cool, and dank, essentially a concrete box that I have to enter by means of a folding staircase. It isn’t a big room, but it’s packed with the furnishings of one. Lots of shelves groan under the weight of books, scrolls, papers, alchemical tools, and containers filled with all manner of magical whatnot.

There’s a silver summoning circle on the floor, and a tiny-scale model of the city of Chicago on a long table running down the middle of the room. The only shelf not crammed full is Bob’s, and even it gets a little crowded sometimes. Bob is my more-or-less-faithful, not-so-trusty assistant, a spirit of intellect that dwells within a specially enchanted skull. I might be a wizard, but Bob’s knowledge of magic makes me look like an engineering professor.

“Are you sure there’s nothing you missed?” I asked.

“Nothing’s certain, boss,” the skull said philosophically. “But you did the equations. You know the power requirements for a spell to continue running through all those sunrises.”

I grunted sourly. The cycles of time in the world degrade ongoing magic, and your average enchantment doesn’t last for more than a few days. For a curse to be up and running since 1945, it would have had to begin as a malevolent enchantment powerful enough to rip a hole through the crust of the planet. Given the lack of lava in the area, it would seem that whatever the Billy Goat Curse might be, I could be confident that it wasn’t a simple magical working.

“Nothing’s ever simple,” I complained.

“What did you expect, boss?” Bob said.

I growled. “So the single-spell theory is out.”

“Yep,” Bob said.

“Which means that either the curse is being powered by something that renews its energy—or else someone is refreshing the thing all the time.”
