Summary	In a remote Manchurian research institute, Dr. Kido, an eccentric scientist, unveils a groundbreaking method to decode human behavior through "excitation curves"—graphical representations of neurological stimuli. His assistant, Oka Kazuo, witnesses the doctor’s fervor as he applies this theory to solve a chilling murder: during a pitch-black train journey through the Xing’anling Tunnel, a gang member is mysteriously killed, leaving 39 suspects. Dr. Kido’s curves allegedly expose latent motives—hatred, jealousy, even murderous intent—pinpointing the culprit with scientific precision. Yet as his discovery gains global acclaim, cracks emerge. Oka notices anomalies in the data, suggesting Dr. Kido’s own psyche may have distorted his results. Dubbed the "Kido phenomenon," the theory unravels into a haunting paradox: could the measurer’s hidden flaws taint every measurement? When Dr. Kido vanishes abruptly, his legacy teeters between genius and delusion. Blending forensic intrigue with psychological suspense, this tale probes the fragile line between objective truth and the shadows within even the sharpest minds—leaving readers to wonder where science ends and obsession begins.
