Digital Coroner

Seven years ago, Lin Shen's fiancée Shen Zhiyu died in a car accident on a rainy night. The official conclusion was that it was "improper operation." But the last heart rate curve on her smart watch pointed to an unexplainable anomaly. Seven years later, Lin Shen has become the most lonely "digital coroner" - able to read the secret connections between door locks, purifier curves, and bracelet pulses, and let the deleted data speak. A case of sudden death of an Internet celebrity kicked off the investigation. Lin Shen used the PM2.5 Fluctuations of the air purifier to target the anesthetized killer, but found an overwritten modification log at the bottom of the case file, and the operator's signature pointed to the accident seven years ago. As more "perfect scenes" were broken down one by one, a data black market organization code-named "Tombstone" surfaced - they sold services that "made evidence disappear," ranging from the accidental death of ordinary employees to Shen Zhiyu's "ghost car accident." When the core evidence on the data ship was completely extracted, Lin Shen finally restored the truth from the afterimage: on that rainy night seven years ago, her heart rate in the last three seconds contained remote-covered steering wheel commands. Four years involved in the case, 120,000 words, from the first Internet celebrity case to the ultimate showdown on the high seas data ship. Lin Shen deleted the "Unclosed Cases" folder, and Shen Zhiyu's case was officially retried. Data remembers everything, and he finally understands her last words.
