I staggered up, spitting out mouthfuls of filth, roared an oath, slipped, and plunged immediately back in. Derisive laughter from on high confirmed I had an audience. My second attempt left me on my back, scraping dung from my eyes. Looking up I saw the whole side of the opera house clothed in interlocking symbols, with one exception. The window from which I tumbled lay bare, a man’s face peering from the hole I’d left. Elsewhere the black limbs of the Silent Sister’s calligraphy bound the shutters closed, but across the broken privy shutter, not even a trace. And leading down from it, a crack, running deep into the masonry, following the path of my descent. A peculiar golden light bled from the crack, flickering with shadows all along its length, illuminating both alley and building.

With more speed and less haste I found my feet and cast around for the Silent Sister. She’d rounded the corner, quite possibly before I fell. How far she had to go until completing her noose I couldn’t see. I backed to the middle of the alley, out of the dung heap, wiping the muck from my clothes to little avail. Something snagged at my fingers and I found myself holding what looked like black ribbon but felt more like the writhing leg of some nightmare insect. With a cry I tore it from me and found the whole of one of the witch’s symbols hanging from my hand, nearly reaching to the ground and twisting in a breeze that just wasn’t there—as if it were somehow trying to wrap itself back around me. I flung it down in revulsion, sensing it was more filthy than anything else that coated me.

A sharp retort returned my gaze to the building. As I watched, the crack spread, darting down another five yards, almost reaching the ground. The shriek that burst from me was more girlish than I would have hoped for. Without hesitation, I turned and fled. More laughter from above. I paused at the alley’s end, hoping for something clever to shout back at Alain. But any witticism that might have materialized vanished as all along the wall beside me the symbols started to light up. Each cracked open, glowing, as if they had become fissures into some world of fire waiting for us all just beneath the surface of the stone. I realized in that instant that the Silent Sister had completed her work and that Alain, his friends, the old man with his wine, and every other person inside was about to burn. I swear, in that moment I even felt sorry for the opera singers.

“Jump, you idiots!” I shouted it over my shoulder, already running.

I rounded the corner at speed and slipped, shoes still slick with muck. Sprawling across cobbles, I saw back along the alleyway, now lit in blinding incandescence shot through with pulsing shadow. Each symbol blazed. At the far end, one particular shadow stayed constant: the Silent Sister, ragged and immobile, still little more than a stain on the eye despite the glare from the wall beside her.

I gained my feet to the sound of awful screaming. The old hall rang to notes that had never before issued from any mouth within it down the long years of its history. I ran then, feet sliding and skittering beneath me—and out of the brilliance of that alleyway something gave chase. A bright and jagged line zigzagged along my trail as if the broken pattern sought to reclaim me, to catch me and light me up so that I too might share the fate I’d fought so hard to escape.

You would think it best to save your breath for running, but I often find screaming helps. The street I had turned into from the alley ran past the back of the opera house and was well-trodden even at this hour of the night, though nowhere near as crowded as Paint Street, which runs past the grand entrance and delivers patrons to the doors. My . . . manly bellowing . . . served to clear my path somewhat, and where townsfolk proved too slow to move I variously sidestepped or, if they were sufficiently small or frail, flattened them. The crack emerged into the street behind me, advancing in rapid stuttering steps, each accompanied by a sound like something expensive shattering.

Turning sideways to slot between two town-laws on patrol, I managed a glance back and saw the crack jag left, veering down the street, away from the opera house and in the direction I’d taken. The people in the road hardly noticed, transfixed as they were by the glow of the building beyond, its walls now wreathed in pale violet flame. The crack itself seemed more than it first appeared, being in truth two cracks running close together, crossing and recrossing, one bleeding a hot golden light and the other revealing a consuming darkness that seemed to swallow what illumination fell its way. At each point where they crossed golden sparks boiled in darkness and the flagstones shattered.

I barged between the town-laws, the impact spinning me round, hopping on one foot to keep my balance. The crack ran under an old fellow I’d felled in my escape. More than that, it ran through him, and where the dark crossed the light something broke. Smaller fissures spread from each crossing point, encompassing the man for a heartbeat before he literally exploded. Red chunks of him were thrown skyward, burning as they flew, consumed with such ferocity that few made it to the ground.
