The shattering of the oil lamp transformed the cramped iron cabin into a nightmare of roaring flames and suffocating black smoke. The fire licked hungrily across the velvet-lined tables, casting grotesque, leaping shadows against the iron bulkheads. Through the blinding haze, the thick outline of Herr Oberstein vanished as he lunged toward a secondary hatchway at the rear of the berth, his heavy sealskin coat trailing sparks.
"The chronometer, Watson! Secure the instrument!" Holmes’s voice cut through the roar of the fire.
I scrambled forward across the listing floorplates, my boots slick with spilled oil. But as my fingers closed around the polished mahogany case of the Greenwich timepiece, a slender, iron-hard hand clamped around my wrist with terrifying precision. It was Henri Le Caron. Despite the smoke and the flickering light, the blind locksmith moved with an uncanny, unbothered grace. Deprived of sight, the pitch-black chaos of the burning cabin was his natural element.
With a swift, practiced twist of his leverage, he forced my arm backward, sending my Service revolver clattering into the flames. In his other hand, a long, thin steel file—a tool of his delicate trade—glinted fiercely as he drove it down toward my throat.
Before the blow could land, a dark shadow erupted through the smoke. Holmes, utilizing the flexible agility of his baritsu training, caught Le Caron’s descending arm mid-air. The two men locked together in a silent, desperate struggle of muscle and bone, silhouetted against the brilliant orange backdrop of the growing blaze.
"Go, Watson!" Holmes gasped, his teeth bared as he strained against the Belgian’s surprising, sinewy strength. "The deck! Oberstein must not cast the secondary codes into the sea!"
Tucking the heavy chronometer case securely beneath my left arm, I threw my weight against the iron companionway door and burst out onto the freezing, snow-swept deck of the Valkyrie. The transition was jarring; the biting North Sea wind instantly whipped the smoke from my eyes, replacing it with the blinding fury of the driving blizzard.
At the stern of the vessel, Herr Oberstein was struggling with the frozen canvas ties of a small whaling cutter. In his gloved hand, he clutched a thick, oilskin pouch containing the false naval coordinates. When he saw me emerge with the master clock, he let out a guttural curse and abandoned the boat ropes, drawing a second, short-barreled pistol from his belt.
"The time is up, Doctor!" he roared over the howling gale, leveling the weapon at my chest.
A sudden, deafening crash shattered the night. The Valkyrie shuddered violently from stem to stern, the steel plates beneath our feet groaning as the vessel collided headlong with the massive, unyielding wall of the Tilbury harbor boom. The impact was catastrophic. The iron bow crumpled, and a great wave of freezing, black river water erupted over the bulwarks, washing across the snow-slicked deck.
Oberstein lost his footing entirely, his pistol firing blindly into the storm clouds as he slid helplessly across the icy timber planks. He crashed heavily against the low stern railing, the oilskin pouch slipping from his grasp and sliding along the ice straight toward the open drainage scuppers.
I lunged forward, throwing myself flat onto the freezing deck, my fingers catching the edge of the waterproof pouch just as it was about to drop into the swirling, black abyss of the Thames estuary. When I looked up, dripping with freezing brine and shivering violently, I found the tall, dark form of Sherlock Holmes standing over the groaning, defeated German spy. Beside Holmes stood Le Caron, his hands securely bound with a pair of steel police bracelets.
The cold dawn of the New Year was finally breaking through the eastern clouds, casting a pale, silver light over the ice-fields of the river. The master clock was safe, the fleet was secure, and the long, freezing shadow of the winter conspiracy had finally met its match.
