Meitantei Conan Magic File 2: Kudou Shinichi Nazo no Kabe to Kuro Lab Jiken

A troubling request reaches Shinichi Kudou when a man accused in connection with his grandmother's death insists that he is innocent and asks the young detective to uncover what really happened.

The clues lead Shinichi through a case involving a mysterious wall and a black Labrador, while details that initially look unrelated begin to reveal the shape of the truth. Solving it gives Shinichi another chance to show the deductive instincts that will later define the detective known as Conan.
