Code of Criminal Investigation

A locked-room poisoning, a carefully made-up corpse, and a will suspiciously neat; a livestream poisoning, with the killer committing the crime in front of hundreds of thousands of viewers; a snowbound mountain lodge, where five old friends vouch for one another and accuse one another; a missing child’s hummed lullaby, the only clue leading into the abyss… As high-IQ crimes grow ever more elaborate, traditional detective work, criminal psychology, and digital forensics take turns in the spotlight, exposing perfect alibis and unraveling time tricks in the digital age.

Every case is a complete, tightly closed loop of deduction. Clues are laid from the crime scene to the interrogation room, while twists hide in the most inconspicuous details: an extra set of footsteps recorded by a smart bracelet, colorless indentations left on a diary’s backing board, or a server time difference hidden in a surveillance timestamp. Eliminate every impossibility, and whatever remains, no matter how bizarre, is the truth.

No heroes, just cases solved. Crime scenes can speak, and all this book wants to do is faithfully record every word they say.
