A Humming Egg in the Rain

My ribs were vibrating before I reached the copper crest of the fishmongers' arcade, which was three minutes too fast for an optical diagnostic bulb that was supposed to stay cold until noon.

The glass egg rested inside three layers of oiled wool against my chest. Every few strides, its core gave off a faint electric shudder that set my collarbone tingling. Down in the canal, the salt tide was slamming against the water gates, but up on the limestone ridge of Gyöngyvár, the only sound was the steady patter of autumn rain against wet green flashing.

A fat grey shape dropped onto a carved stone gargoyle two paces ahead, kicking loose a shower of moss.

Hetyke shook the water from his slate-colored wings with deliberate, exaggerated misery. He pinned me with an amber stare that suggested I had personally arranged the morning drizzle just to spoil his plumage.

"Don't give me that look," I said, catching my breath against the brick chimney. "It's three rooftops to Nyírbátori's workshop. You flew twenty yards."

Hetyke clicked his curved beak twice, raised one taloned foot, and tapped the stone. It was the universal gesture of the Gyöngyvár Courier Guild's most pampered falcon demanding his flight fee.

"Three seeds," I told him, reaching into my pouch. "One for the launch, two upon arrival."

The bird did not blink. He made a low, rattling hiss in his throat and turned his head away, gazing toward the harbor with profound indifference.

"Fine. Four roasted sunflower seeds, salted. But you check the chimney smoke over the canal gap first."

I shook four flat seeds onto my damp palm. Hetyke snapped them up in four blinding pecks, swallowed with a satisfied twitch of his crop, and launched into the gray mist without a sound.

I tucked the woolen bundle tighter into my jacket. The glass egg thrummed harder, warm enough now to heat the damp wool through my shirt. If the internal vacuum seal cracked before I reached the optician, thirty silver groschen of guild credit would vanish into a cloud of sulfurous smoke, taking my eyebrows with it.

Below the eaves, a muffled rumble rolled through the canal basin. It wasn't thunder. The percussion had the dry, iron crack of a naval mortar, followed by the churn of heavy paddle wheels churning against the current.

I crept to the lip of the limestone cornice and peered down through the rain.

The outer waterway of the Szent-György lock was choked with ships, none of them carrying the yellow pennants of our city merchants. Broad, black-hulled river galleons from the Iron-Barge Consortium were wedged shoulder to shoulder between the embankment walls. Their iron rams were already chained across the main water gates, sealing the mouth of the bay. On the rear fighting deck of the nearest barge, a spotter in a grease-stained brigandine held a long brass spyglass, sweeping the upper balconies.

I pulled back behind the chimney flue before his glass caught the sheen of my wet leather coat.

The privateers weren't just blockading the salt trade. They were staking the locks shut, trapping every barge, skiff, and gondola in the district.

The only way across the gap was above.

Between the fishmongers' arcade and Nyírbátori's clock tower stretched a nine-foot void of open air, fifty feet above the churn of the canal sluice. Rain had turned the lead gutter lining on the opposite side into a slick slide of black grease. A frayed hemp stay-line ran from my chimney down to a drain anchor near the far gable, slick with moisture.

I checked the straps on my soft-soled courier boots, ground my heels into a patch of rough lime mortar to clear the roof grime, and tightened my grip on the wool parcel.

I took three rapid paces along the narrow copper ridge, hit the edge at a flat sprint, and launched outward.

For a split second my stomach dropped into the gray canal mist. I caught the guide rope with my left forearm, letting the hemp burn through my wet sleeve to arrest my momentum, and swung my boots forward. My soles slapped the opposite lead flashing with a sharp thud. My heels skidded six inches, but I dropped low, digging my fingertips into the limestone mortar joints until my slide halted.

Inside my jacket, the diagnostic bulb gave a nervous pulse of amber light, but the casing held whole.

A soft croak came from the copper drainpipe overhead. Hetyke sat perched on the gutter lip, preening a wet tail feather as though my leap had been moderately clumsy and unworthy of polite applause.

"Appreciate the moral support," I muttered, hauling myself up the wet tiles toward the workshop dormer.

The hinged skylight was latched, but Master Nyírbátori's latches were as familiar to me as my own pocket knives. I slipped a thin brass shim between the lead frame and the sash, flicked the toggle, and pushed the glass upward.

Warm, dry air rushed into my face, rich with the heavy scents of camphor, cedar shavings, and refined whale oil. I slid feet-first through the gap, caught the ceiling joist with one hand, and dropped silently onto a braided rag rug.

Clocks ticked from every corner of the long attic room. Brass pendulums sliced back and forth with measured clicks, while rows of polished magnifying lenses sat nestled in velvet-lined cedar drawers.

At a long workbench beneath a zinc reflector hood, a stooped figure in an ink-stained smock was peering into the gears of a brass carriage clock. Master Tibor Nyírbátori did not raise his head from his work, though his round magnifying spectacles glinted in the oil-lamp glare.

"You took the gutter route across the fishmongers," the old lens-grinder said, his gravelly voice competing with the clatter of a dozen escapements. "Only a Váryszegi lands on my rag rug without shaking the ceiling luster."

"And only a Váryszegi brings your mail before the egg boils in its own skin," I said.

I peeled back the layers of soaked wool and lifted out the glass bulb.

The device was the size of an ostrich egg, its blown quartz surface etched with fine radial grooves. Inside, a suspended core of pale yellow vapor was churning into an angry, pulsing crimson, vibrating against the workbench with a low mechanical whine.

Nyírbátori dropped his tweezers. He seized a pair of padded brass tongs from a brazier stand, lifted the bulb by its mounting ring, and set it into a velvet-lined lead socket.

"Look at the frequency decay," Nyírbátori whispered, adjusting his spectacles. "The orbital broadcast from the high arrays is drifting off-axis. The privateer fleet has choked the outer light conduits with coal smudge."

"They've chained the water gates shut, too," I said, wiping rainwater from my chin. "The whole lower basin is locked."

"Worse than that, lad." The old optician turned a brass vernier knob on the socket, stabilizing the bulb's hum into a steady, subdued purr. "The city council thinks Botond Várkonyi came for the salt tax. He didn't. He came because Gyöngyvár's defensive sun-shield is uncoupled."

Nyírbátori reached into a heavy iron chest beneath his bench and pulled out two items.

The first was a flat, octagonal brass disc etched with concentric vernier dials and interlocking geared rings—the Master Alignment Cipher. The second was a heavy, dented tin flask wrapped in braided twine, radiating glorious, mouth-watering heat.

"This cipher holds the frequency calculations for the harbor bell towers," Nyírbátori said, thrusting the disc into my hands. "To throw the solid-light shield over the sea gates, we must align the three ancient spires. But the primary receiver needs its focusing medium. An emerald sun-prism."

"Where is it?" I asked, unscrewing the cap of the tin flask. The rich, roasty aroma of spiced chicory and roasted chicory root bloomed into the cold attic air, sweet with honey.

"In the attic of Sarolta Kenesei," Nyírbátori said grimly. "The milliner. She believes it is an ornamental paperweight for pinning bonnet lace."

I took a long, burning gulp of the chicory brew. Warmth flooded my chest, cutting straight through the river dampness in my bones.

"Sarolta guards her lace with an iron umbrella," I said. "She threw a potted marigold at my head last Tuesday."

"Then duck faster, Kende," Nyírbátori replied. "Without that prism, the city gates fall before sunset."

Before I could cap the flask, a deafening screech tore through the sky above the workshop.

A massive iron-shod ballista bolt sheared clean through the stone bell-cote three rooftops away. Shards of crushed limestone and black slate exploded outward in a deafening spray, raining across the skylight like grape-shot.

Through the broken opening, thick plumes of oily black smoke rose over the canal rooftops, blotting out the gray autumn light. The privateers were no longer aiming at the water. They had opened fire on the skyline.
