Elder Code

In near-future Japan, a pharmaceutical scientist turns a chain of nursing homes into a covert mortality-trimming lab to bury a drug's lethal side effect. When a young prosecutor spots the statistical anomaly, he discovers that every digital clue he gathers is legally inadmissible—because Japan's evidence code still worships paper and physical custody. This is a thriller about algorithmic homicide, judicial blindness, and the uncomfortable truth that genius crime only exists when the law looks backward.
