The city had planned the canal cleanup for months. The old waterway had not been fully drained in years, and everyone expected the usual things to appear from the mud: bicycles, shopping carts, old tools, and maybe a few forgotten pieces of junk. Declan Hurst, a maintenance supervisor with more than twenty years of experience, had seen almost everything a canal could hide. He arrived before sunrise, checked the pump reports, spoke with his crew, and gave the order to begin draining. At first, nothing seemed unusual. The water level dropped slowly, the mud appeared, and workers moved carefully along the edge. But by late afternoon, one of the younger workers stopped near the western bend and stared down at something half-buried below. “Declan,” she called, her voice suddenly serious. “You need to see this.”

Declan walked over, expecting another rusted machine part or a piece of old construction equipment. But when he looked down, he immediately knew this was different. The object was long, rounded, and covered in black mud. At first glance, it looked like a large pipe. But then he saw the details: small round openings, metal fins, and a curved steel body that did not belong in a city canal. Nobody spoke for a few seconds. The shape was too strange to ignore and too large to move without help. Declan looked closer, trying to understand what he was seeing. The more mud slipped away from the sides, the clearer the outline became. It was not a pipe. It was not a storage tank. It looked like a submarine.
