Lu Yan is a key member of the municipal bureau's document examination division, specializing in handwriting, seals, and document authenticity. When the supposed “suicide” of an entrepreneur surnamed Zhang lands on his desk, everyone expects him to stamp his verdict on it.
Under the magnifying glass, a 0.1-millimeter difference in the handwriting reveals an imitation. Under ultraviolet light, the fluorescence of two kinds of ink exposes a second layer of writing. Under the microscope, forged marks along the seal's edge silently testify to the truth.
“This wasn't suicide. It was murder.”
Three days and one forensic report will decide not only the fate of several families, but also whether the entire document examination division survives. As the investigation deepens, Lu Yan discovers that behind the case lies a criminal organization skilled in document forgery. Their goal is far greater than taking one life...
Others solve cases with surveillance footage, testimony, and footprints. Lu Yan needs only paper and ink.
He reads people through their handwriting, dates documents by their ink, identifies forged seals, and reconstructs documents.
There is no case he cannot solve, no trace that can remain hidden.
In a city where workplace rivalries simmer beneath the surface and cold cases turn with every new revelation, watch this all-around document expert wield ink as a blade and pursue the killer to the end!
