Conan, Kogoro, and Ran go to a restaurant that is shaking because of construction next door. They go back the next day only to find that the man running the restaurant is dead. At first it looks like the construction made a vase fall over and hit him on the head, killing the owner, however, the construction wasn't happening at the estimated time of death. Then Kogoro accidentally hits his head and suddenly becomes a very good detective and solves the case. But as usually he missed something, therefore Conan puts him out and finishes the deduction show.
