Let those who lament the — vastly overstated — train fixation of Freeman Wills Crofts take note: Tokyo Express (1958) by Seichō Matsumoto contains so much red-hot timetabling action that I half expected it to be written by someone called Bradshaw. And it’s fitting perhaps that such a small, quiet crime — a double suicide on a gloomy beach — should result in a quiet and low-key investigation, but for me there needs to be a little more to show for all the hours spent looking at the precise movements of trains, ferries, and more. The essential culmination of this is clever, but the route we take to get there could have used a few faster, twistier sections of track.
