The Error Hunter

I can see the “margin of error” on everyone, including the one left by a killer at a crime scene. Jiang Chen, a former police academy student, uses a talent dismissed as “delusional disorder” to find a button at a secondhand market and identify the culprit behind a cold case from three years ago. But when he joins the Special Crime Investigation Bureau, he discovers that people with special abilities have already infiltrated the entire city, and the margin of error on everyone points in the same direction. Standing there is his father, who disappeared twelve years ago.
