“Okay,” I said. “So the office doesn’t have computers. But the rest still applies.”

Michael looked up at me and showed me his teeth in a ferocious grin. “When?”

I watched my little ball of sunshine intensely as the water came down. For maybe half a minute nothing happened, except that we got drenched. It was actually kind of surprising how much water was coming down—surprising in a good way, I mean. I wanted lots of water.

Somewhere around the sixty-second mark I felt my spell begin to flicker, its power eroded away by the constant downpour.

“Wait for it,” I said. “Ready…”

At two minutes my spell buckled, the connection to the other sprinklers snapping, the fire in my hand snuffing out. “Michael!” I shouted. “Now!”

Michael grunted and flung open the door. Before he’d stepped through it there was a sudden flutter of faltering power in the air, and the holy blade blazed with light brighter than the heart of the sun itself.

He plunged through the door, and as the burning light of Amoracchius emerged into the station at large, dozens or hundreds of hob throats erupted into tortured cries. The sound of the wicked faeries’ screams was so loud that I actually felt the pressure it put on my ears, the way you can at a really loud concert.

But louder still was the voice of Michael Carpenter, Knight of the Cross, avenging angel incarnate, bearer of the blade that had once belonged to a squire called Wart. “Lava quod est sordium!” Michael bellowed, his voice stentorian, too enormous to come from a human throat.“In nomine Dei, sana quod est saucium!”

After the Sword had left the room, I could see that all the office lights had come back, as well as those outside. “Mouse!” I screamed. “Stay! Guard the wounded!” I hurried after Michael and glanced back behind me. Mouse trotted forward and planted himself in the doorway between the hobs and the people in the office, head high, legs braced wide to fill the space.

Outside the sprinklers were doing a credible impersonation of a really stinky monsoon. I slipped in a puddle of water and burning hob blood a few feet outside the door. The light from the Sword was so bright, so purely, even painfully white that I had to shield my eyes with one arm. I couldn’t look directly at Michael, or even anywhere near him, so I followed him by the pieces of hob he left in his wake.

Several wicked faeries had been struck down by Michael’s sword.

They were the lucky ones.

Many more—dozens that I could see—had fallen too far away for Michael to have reached them with the blade. Those were simply lumps of smoldering charcoal spewing columns of greasy smoke, their meat flash-cooked away from bone. Some of the soon-to-be-former hobs were still thrashing as they burned.

Hell’s bells.

I don’t call him the Fist of God as a pet name, folks.

I followed Michael, alert for any dimming of the Sword’s light. If any of the sprinklers in the building were a different model from the one I’d used to focus my spell, it wouldn’t have been able to heat them and trigger them. If Michael wound up plunging back into the myrk, then the hobs, afforded a measure of protection from the light, would gang up on him—and fast.
