The October mist rolled off the river in thick, damp ribbons, clinging to the weathered red-brick facade of the Blackwood County Courthouse. It was six o'clock in the morning, an hour usually reserved for the sweepings of the night watch and the occasional stray dog searching for scraps behind the tavern across the square. On this particular Tuesday in 1897, however, a small crowd had gathered at the base of the courthouse steps, watching three sweating draymen wrestle a massive wooden crate off the back of a flatbed wagon.

The crate was constructed of heavy pine, reinforced at the corners with iron straps, and stamped in faded black ink with German lettering. Ruhmkorff, Frankfurt, it read on one side, while the other bore the stark, cautionary imprint: Fragile – Optical and Electrical Apparatus – Glassware.

Standing on the top step, wrapped in a wool overcoat that smelled faintly of pipe tobacco and damp dog, was Arthur Pym. Pym was the chief clerk of the court, a man whose forty years in the municipal civil service had left him with a permanent stoop, a dry cough, and a deep-seated suspicion of anything that did not arrive wrapped in red tape and bound with string. Beside him stood Professor Thaddeus Vance, late of the Department of Applied Physics at the local institute, who was looking at the crate with the breathless, wide-eyed adoration usually reserved for newborn infants or victorious generals.

"Easy with the rope, you fool," Vance barked, his voice cutting sharp through the morning chill as one of the draymen lost his footing on the slick cobblestones. "If you crack the Crookes tube, I assure you the County Board will attach your wages until the turn of the next century."

"It weighs a ton, Guv'nor," the lead drayman grunted, wiping his brow with a greasy sleeve. "Feels like you've got a dead horse packed in sawdust in there."

"What we have in there," Vance replied, adjusting his wire-rimmed spectacles with a gloved thumb, "is the vanguard of modern scientific jurisprudence. It is the end of conjecture. The death of the false oath."

Pym pulled a silver pocket watch from his waistcoat, snapped the lid open, checked the time, and snapped it shut with an audible click. "What we have in there, Professor, is three hundred and fifty dollars of the taxpayers' money, authorized by a magistrate who was three sheets to the wind at the annual dinner, and a crate that is currently blocking the main entrance. If Magistrate Hargreaves arrives at eight and finds his doorway obstructed by Frankfurt sawdust, scientific jurisprudence will find itself sitting on the curb in the rain."

With a collective groan, the draymen gave a final heave. The iron wheels of their hand-truck skittered across the wet flagstones, and the crate rolled through the double oak doors into the grand vestibule. The smell of the courthouse—a mixture of floor wax, old parchment, coal dust, and cheap gin left behind by yesterday's vagrants—seemed to swallow the damp aroma of the pine crate.

The vestibule was a cavernous space lined with yellowing plaster and dark mahogany paneling. At its center rose a grand staircase leading to the main courtroom on the second floor, but Vance directed the workmen toward a small, windowless alcove situated beneath the stairs. It was a dark, cramped room that had previously served as a storage closet for spare spittoons, broken chairs, and dusty volumes of land registry records dating back to the late eighteenth century.

"Here?" Pym asked, eyeing the narrow doorway with a furrowed brow. "You intend to set up a revolution in human knowledge in the broom closet?"

"It requires darkness, Mr. Pym," Vance said, already pulling a crowbar from his satchel and handing it to the nearest workman. "The light produced by the fluoroscopic screen is subtle. It is an elusive, ghostly luminescence. Sunlight is its enemy. Besides, it keeps the curious away from the high-voltage connections. We are dealing with potential differences of forty thousand volts. A careless finger against the primary terminals would do more than merely clear a man's sinuses; it would render his testimony entirely posthumous."

The crate yielded to the crowbar with a sharp, splintering screech that echoed up into the empty gallery above. As the pine boards were pulled away, revealing layers of coarse horsehair packing and oilcloth, the inner anatomy of the machine began to emerge.

First came the battery bank: twelve massive glass jars set in a lead-lined oak box, each filled with sulfuric acid and zinc plates, smelling strongly of acrid chemicals. Next was the induction coil, a heavy cylinder wrapped in yards of dark silk-insulated copper wire, flanked by heavy brass binding posts and a gleaming mechanical interrupter that looked like an oversized brass beetle. Finally, wrapped in thick cotton wool and nestled inside a velvet-lined box of its own, was the heart of the apparatus: a pear-shaped glass bulb with two wire electrodes sealed into its sides, its interior evacuated to an almost perfect vacuum.

Vance lifted the glass bulb with a reverence that made Pym instinctively

Vance lifted the glass bulb with a reverence that made Pym instinctively take a step back, his polished boots heel-clicking against the damp flagstones. The professor held the delicate sphere up toward the hiss of a nearby gas jet, his eyes narrow behind his wire-rimmed spectacles as he inspected the glass for hair-line fractures or imperfections in the blown neck. Within the transparent husk, suspended like a pair of silver needles in an empty sky, hung the platinum electrodes. To Pym, it looked less like an instrument of law and more like the dried chrysalis of some monstrous, tropical insect.

"The Crookes tube," Vance murmured, his breath forming a faint halo on the cool surface of the glass. "A miracle of vacuum technology. Herr Röntgen himself demonstrated
