Advertising balloons in department stores, the waterline of private sailboats, spring steel sheets from shipyards, heavy old-fashioned locomotives - these cold objects all have their own language in Osaka Keikichi's novels.
The corpse does not speak, but the blood stains on the ropes, the clay on the bottom of the boat, the crows on the ice and the decoys beside the railway tracks can prove it.
This book contains six reasoning works, using precise on-site observation and bold physical tricks to reconstruct seemingly unsolvable deaths. The design of the mechanism is amazing, but the secrets hidden in the human heart are even darker.
When the machine starts to run, who is controlling it, and who ultimately dies in his own plan?
