Dr. Edgar Hastings was the most rational man Edinburgh had produced in a generation. At thirty-eight, he held two professorships—one in forensic chemistry at the University of Edinburgh, another in clinical medicine at the Royal Infirmary. His colleagues described him as precise, methodical, and possessed of a mind that operated like a well-calibrated instrument. His fiancée, Clara Livingston, described him as the most dependable man she had ever known. None of them had seen him on Tuesday nights. The first newspaper article appeared on a Thursday morning. Edgar read it over breakfast in the dining room of his townhouse on Royal Mile, a cup of tea steaming beside the folded paper. The article described the death of Reginald Thorne, a slave trader whose business had flourished in the decades before abolition and who had continued his operations through connections and bribery long after the practice had become illegal. Thorne had died in his sleep. The coroner ruled natural causes—heart failure, the result of advanced age and what the doctor euphemistically called "irregular habits." Edgar read the article twice. The second time, he noticed something the newspaper had omitted: Thorne had died with a small puncture wound on the side of his neck, barely visible, easily overlooked. The coroner had attributed it to a mosquito bite. Edgar knew it was not a mosquito bite. He knew because he had designed the toxin that had killed Thorne. He set down the newspaper and picked up his teacup. His hand did not shake. It never shook. But inside his chest, something that he had never named before stirred, like a door opening in a house he did not know he owned. --- The second death occurred five days later. Arthur Pendelton, a factory owner who had knowingly sold defective machinery that had killed seventeen workers, was found dead in his bed. Same puncture wound. Same coroner's ruling: natural causes. Same toxin. Edgar sat in his laboratory at the university and stared at the equipment on his workbench—flasks, beakers, distillation apparatus, vials of plant extracts that he had spent years cataloging and classifying. He was a man who understood chemistry. He knew that the toxin used in both deaths required a combination of substances that fewer than a dozen people in all of Scotland could prepare. He was one of those twelve people. "Edgar?" He looked up. Professor James Moriarty stood in the doorway of his laboratory, a tall, thin man with sharp eyes and a sharper mind. Moriarty was Edgar's former supervisor, the man who had recommended him for both his professorships, the man who knew more about Edgar's work than Edgar knew himself. "You look troubled," Moriarty said. "I've been reading the newspapers." Moriarty stepped into the laboratory and closed the door behind him. "The deaths in the news. I see you have noticed them." "You know about them?" "I know about everything that happens in this city, Edgar. It is my profession to notice patterns." Moriarty moved to the window and looked out at the gray street below. "Tell me, have you been dreaming recently?" Edgar felt the question land inside him like a stone dropping into water. "Yes," he said. "I have been dreaming." "Describe them." Edgar opened his mouth and found that he had no words. How do you describe a dream that feels more real than waking life? How do you explain that on Tuesday nights, you close your eyes in your study and open them in a different room, performing actions with a precision and coldness that your waking self would find horrifying? "I lose time," he said finally. "On Tuesday nights. I go to bed at ten. I wake up at three in the morning, and sometimes I am not in my bed. Sometimes I am walking on the streets. Sometimes I am in my laboratory." Moriarty turned from the window. His expression was unreadable. "And do you remember what you do during these episodes?" "No. I remember nothing. Except—" He paused. "Except sometimes I wake up with things in my pockets. Keys. Small pieces of paper with numbers written on them. A vial last Tuesday that I do not recognize." Moriarty was silent for a long time. When he spoke, his voice was gentle, the way a surgeon speaks to a patient before delivering bad news. "Edgar, I need you to be honest with me. Have you ever experienced what psychologists call dissociation? A splitting of the consciousness, where one part of the mind operates independently of the other?" "No," Edgar said. But he had. He had felt it, in the months leading up to Thorne's death—a sensation of stepping backward out of his own body, watching himself move and speak and think from a distance, like a man watching a play about himself. "I have not," he said. "But I think I am becoming someone who has." --- Edgar began to keep a journal. Every night, before going to bed, he wrote down everything he had done during the day. Every morning, upon waking, he recorded where he had been, what he had done, what he remembered. The journal became a map of a territory he could not navigate while walking it—a record of a life he was living but not remembering. The pattern emerged over three weeks. Every Tuesday night, between 10:00 PM and 3:00 AM, Edgar was not himself. He was someone else. Someone who moved through Edinburgh with purpose and precision, visiting the homes of men who had done evil and escaping justice. Someone who prepared a toxin from plants and chemicals that Edgar had purchased for legitimate scientific purposes and assembled into something that could end a life with a single puncture wound. He found the key on a Friday. It was in his coat pocket after a Tuesday episode. It was a small brass key, unmarked, that opened a locked cabinet in the basement of the laboratory—a cabinet Edgar used for storing hazardous materials. He went to the basement on Saturday morning, while the university was empty, and opened the cabinet. Inside were twelve small bottles, each one labeled with a name and a date. The names were men he recognized from the newspapers—Thorne, Pendelton, and ten others, all of whom had died of "natural causes" over the past eighteen months. All of whom had committed crimes and escaped justice. The twelfth bottle was unlabeled. It was full. Edgar stood in the basement and felt the floor tilt beneath him. The man who was killing these men was him. Or rather, the man who was killing them was a version of him that existed only during those five hours every Tuesday night—a version of himself who was cold and efficient and absolutely convinced of his own righteousness. He thought of Clara. He thought of her paintings, her laughter, the way she looked at him across a crowded room with an expression that was equal parts affection and curiosity. She knew him. Or rather, she knew the Edgar Hastings who existed from Wednesday morning through Monday night. She did not know the man who operated in the dark hours of Tuesday, executing a justice that the law could not deliver. Who was next on the list? He took the unlabeled bottle and examined it. There was no name, but there was a date scrawled on the label in his own handwriting: next Tuesday. One week. Seven days. In seven days, the man who lived in the Tuesdays would choose his next target. And Edgar had no way of knowing who that target would be. He thought of Moriarty. He thought of the professor's gentle voice, his knowing eyes, his question about dissociation. Moriarty had known. He had known all along. He thought of Clara. If the next target was someone she knew—if the Tuesday man decided that her father, or her brother, or her friend needed to be punished—Edgar would never know until it was too late. --- Edgar sat in his laboratory on Tuesday night at 9:30 PM. He had prepared two cups of tea. One for himself. One for the man who would wear his body from ten until three. He placed both cups on the desk. He sat in his chair. He lit the gas lamp and watched the flame flicker. "If you exist," he said to the empty room, "then I have a question for you. Are we punishing evil, or are we giving ourselves permission to indulge our own cruelty under the pretense of justice?" The lamp flickered. The gas hissed. Edinburgh slept beneath a blanket of fog. Edgar picked up his journal and opened it to a blank page. He picked up his pen. And he began to write. He wrote the story of Reginald Thorne, not as a newspaper would tell it, but as he knew it—the bribes, the silenced witnesses, the families destroyed by a man who had turned human beings into commodities. He wrote it with the precision of a scientist and the fury of a man who had spent his entire life believing that reason and evidence would always triumph, and who was now discovering that some evils are too deep for reason and too entrenched for evidence. He wrote until 10:00 PM. At 10:00 PM exactly, Edgar Hastings felt himself step backward out of his body. He watched, from somewhere inside his own mind, as his hands picked up the second cup of tea—the cup he had prepared for the Tuesday man—and drank it in one slow, deliberate swallow. Then his body stood up, walked to the cabinet, retrieved the unlabeled bottle, and placed it in his coat pocket. Edgar tried to follow. He tried to reach the part of himself that was now driving, now thinking, now choosing the next target. But he was behind glass, watching through a window he could not open, a prisoner in his own mind. His body left the laboratory. It moved through the streets of Edinburgh with purpose and precision, disappearing into the fog. Edgar sat in the darkness of his own skull and listened to the city breathe and wondered, for the first time in his rational, methodical, scientifically minded life, whether some doors, once opened, can ever be closed. Outside, Edinburgh slept beneath its blanket of fog, unaware that two men lived in one body, and that one of them was very, very good at what he did. © 2026 - Authored by Z R ZHANG ( EL9507135 -- パスポート番号[ちゅうごく] 중국 여권 번호 Номер паспорта หมายเลขหนังสือเดินทาง Passnummer رقم جواز السفر CHN Passport) The aforementioned Author hereby grants to OXFORD INDUSTRIAL HOLDING GROUP (ASIA PACIFIC) CO., LIMITED (BRN74685111) all economic property rights, including but not limited to the rights of: reproduction, distribution, rental, exhibition, performance, communication to the public via information network, adaptation, compilation, commercial operation, authorization for third-party use, and rights enforcement.
