Inspector Imanishi Investigates by Taiyō Matsumoto

A veteran Tokyo detective investigates the murder of an unknown man found near train tracks, patiently following slender leads—regional dialects, travel timetables, and connections in literary and art circles—across cities and remote towns. His meticulous legwork uncovers a long-guarded secret involving identity, ambition, and the burdens of postwar poverty and stigma, ultimately revealing how a carefully constructed life was built on a past that could not stay buried.
