As he solved cases again and again, Conan finally encountered the mysterious organization that caused him to shrink. The members of the mysterious organization all have unique skills and have created unprecedented unsolved cases. Conan defeated them one by one, recorded their sins in the form of parchment, made them into drifting bottles and threw them into the sea, and then faced the final darkness alone. The parchment drifted to China through ocean currents. A kind-hearted new author picked up the parchment and decided to make it public to alleviate the pain of chasing after it.
Purpose: I hope to bring the fun of mystery novels to everyone
