Kirigakure Bell

1888, London. Thames fog engulfed the third body. All that was left at the scene was a mystery, the secret room, and the silver pocket watch clutched in the deceased's hand. Arthur Blackwood stared at the watch, his fingers trembling slightly. "To E. H." Is engraved on the back of the case, and there is an arc-shaped wear mark next to the crown, which is the unique habit of his mentor Edgar Hawthorne. Three years ago, his mentor died unjustly in prison due to his wrong reasoning. Three years later, the teacher's relics appeared in the hands of a stranger. There was also a scrawled note hidden inside the pocket watch: Tonight at eight o'clock, dock warehouse. Is this a clue left by my mentor before he died? Or some kind of fatal invitation? What makes Arthur even more uneasy is that the perfect criminal he has been tracking for three years seems to have returned to London. When the truth approaches, do you dare to face everything you have destroyed with your own hands?
