The Puzzle of the Sunken Compass
Episode 4: The Shipwright’s Tale
Tracking down an aging shipwright who had built the imperial warship’s binnacle decades ago, Jonah sought advice on how to bypass the missing lodestone needle’s security lock. The shipwright, an 80-year-old master craftsman living in a weathered seaside cottage, listened intently to Jonah’s description of the heist. An aging shipwright confesses to forging decoy housing brackets to facilitate the needle’s midnight extraction under extreme coercion from Captain Vance’s enforcers. The shipwright handed Jonah a heavy brass tuning cylinder, explaining that it could be used to replicate the exact magnetic frequency of the missing lodestone needle if vibrated at 432 hertz. This vital piece of technical wizardry gave Jonah a fighting chance to open the underwater cache without triggering the deadly depth-charge trap. He thanked the wise old shipwright, sprinting back to his diving boat as the afternoon storm clouds began to gather over the choppy coastal waters.
Dredging Up the Past
Jonah initiates a sub-surface sonar sweep along the deep shipping trench, locating a scuttled tender boat resting on the muddy ocean floor. Anchoring his diving vessel directly above the sonar contact, Jonah donned his mixed-gas rebreather suit and slipped over the side into the cold, green water. He descended along a weighted descent line, his underwater headlight cutting through the swirling silt as he dropped twenty fathoms toward the ocean floor. Resting beside the sunken tender boat was a heavy steel diving bell connected to an umbilical cable stretching toward a cave opening in the trench wall. This was Captain Vance’s clandestine underwater operational base, where the stolen compass needle and salvage gear were hidden away from prying eyes. Jonah swam cautiously toward the cave entrance, his heart pounding in his chest as he prepared to confront the rogue diving captain in his own subterranean domain.
