In a sluggish wholesale market, a strange and eerie rumor quietly spreads that many merchants who received dunning letters have suddenly disappeared one after another, their whereabouts unknown. There are even rumors that they have met with misfortune. Yet, someone claims to have seen the victims. The Three Musketeers, upon receiving a call for help, secretly begin their investigation, only to receive threatening letters in succession and even see people who have been "dead for a long time."

Why does the victim at the murder scene vanish in the blink of an eye? How does the door leading to the rooftop mysteriously disappear? Who are the two legless figures on the foggy street? Is the brown, large face really a ghost, and why doesn't it have a body? Is the subpoena a debt collection letter from a ghost or a meticulously arranged conspiracy? The Three Musketeers and Mantee use a four-corner cipher to unravel the layers of mystery, and the bizarre secrets of the "deceased" emerge from the shadows...
