Jack Mercer was a quiet history enthusiast, a man who spent his days writing articles about forgotten train stations and war relics. Life was simple, and he preferred solitude. But everything changed last October when Jack received an extraordinary letter. The envelope was yellowed and crinkled, looking as if it had been hidden away for decades. Inside, he found a single typed page, directing him to Harlow Junction and warning him about a mysterious train. The words sent a shiver down his spine: “When the fog rolls in, wait by the signal house. You’ll hear the whistle. But do not board. You won’t come back.” Intrigued, Jack recalled the haunting story of train Number 109, which had vanished into the fog back in 1924, leaving no trace behind. Determined to uncover the truth, Jack packed a bag and set off for Harlow Junction. Arriving at the crumbling depot, he felt a mix of excitement and fear. As the fog rolled in, he stood by the rusted signal house, heart racing as he heard the distant whistle. Suddenly, a ghostly train emerged from the mist, just as the legends foretold. Jack felt a powerful pull toward the train, yet the warning echoed in his mind. Did he dare to board?
