Finally, it began to happen, at least three hours after nightfall. A stillness crept into the city. The only people on the street were armed and running. Once, a dozen members of a Hoegbotton militia hurried by in tight formation, their weapons gleaming with the reflected light of the fires. Then, for a while, nothing. The moon and the one or two remaining streetlamps, spluttery, revealed an avenue on which no one moved, where the lack of breeze was so acute that crumpled newspapers on the sidewalk lay dead-still.

“It’s coming,” Sybel muttered. “I don’t know what it is, but it’ll happen soon.”

“Nonsense,” I said. “It’s just a lull.”

But a chill had crept over me, as it seemed to have crept over the city. It lodged in my throat, my belly, my legs. Somehow, I too could feel it coming, like a physical presence. As if my nerves were the nerves of the city. Something had entered Ambergris. (Creeping through your nervous system, the gray caps’ spores, creating fear and doubt, right on schedule. I’d put the antidote in your food, but an antidote only works for so long against the full force of such efforts.)

The streetlights went out.

Even the moon seemed to gutter and wane a little. Then the lights came back on—all of them—but they were fungus green, shining in a way that hardly illuminated anything. Instead, this false light created fog, confusion, fear.

Sybel cursed.

“Should we barricade the window?” I asked.

“Not yet,” Sybel said. “Not yet. This might be the end of it, you know. This might…” Now it was his turn to trail off. We both knew this would not be the end of it.

We began to see people again on the street below. This time, they ran for their lives. We could not help them without endangering ourselves, and so we watched, frozen, at the window, beyond even guilt. A woman with no shoes on, her long hair trailing out behind her, ran through our line of vision. Her mouth was wide, but no sound came from it. A few seconds later, some thing appeared in the gutter near the sidewalk. It tried to stand upright like a person, tottered grotesquely, then dropped all pretense and loped out of sight after the woman. The roar of the Kalif’s mortar fire followed on its heels.

“What was that?” I hissed at Sybel. “What in Truff’s name?”

Sybel didn’t reply. Sybel was whispering something in his native language, the singsong chirp of the Nimblytod Tribe. I couldn’t understand it, but it sounded soothing. Except I was beyond being soothed.

Then a man came crawling down the street, shapes in the shadows pulling at his legs. Still he crawled, past all fear, past all doubt. Until, as the Kalif’s mortars let out a particularly raucous shout, something pulled him off the street, out of view.
