The Puzzle of the Sunken Compass
Episode 2: The Bottom of the Basin
Searching the muddy floor of the drained dry dock during low tide, Jonah discovers heavy bronze ballast plates inscribed with naval artillery coordinates. The plates had been discarded near the ship’s propeller shafts, half-buried in the thick black silt and marine debris. Jonah wiped the slime from the bronze surface using a stiff wire brush, revealing deeply engraved numbers and military seal stamps dating back to the imperial defense ministry. These ballast plates were designed to stabilize underwater torpedo silos, proving beyond a shadow of a doubt that the imperial dry dock was directly connected to a secret military bunker system. The presence of these plates in the dry dock basin indicated that someone had been dismantling the subterranean munitions cache from the inside using heavy salvage equipment. Jonah loaded the heavy bronze plates into the back of his truck, knowing they held the cryptographic keys needed to unlock the mystery of the magnetic distortions. The puzzle was deepening, drawing naval intelligence, salvage experts, and ruthless saboteurs into a dangerous confrontation beneath the harbor waters.
Rust and Ruin
Forensic metallurgy analysis conducted at the harbor authority laboratory revealed startling clues about the saboteurs’ operational methods. Forensic metallurgy reveals the plates were recently cut with an underwater oxy-arc torch, proving premeditated sabotage by experienced marine technicians. The slag deposits left around the cut edges contained traces of exotic chemical fluxes used exclusively by deep-sea oil rig construction crews. Jonah cross-referenced the employee rosters of every commercial diving company operating in the tri-state area, searching for specialists certified in hyperbaric welding and underwater demolition. One name stood out from the database: a disgraced former naval diving instructor named Captain Vance, who had been dishonorably discharged for illegal salvage operations years earlier. Captain Vance possessed both the technical expertise to operate underwater cutting torches and the tactical knowledge required to navigate the classified military bunker system. The trail was pointing toward the deep shipping trenches outside the harbor breakwaters, setting the stage for a perilous underwater showdown in the freezing ocean depths.
