Ep. 571: Detective Boys investigate a haunted warehouse rumored to hold disappearing treasure.

571

The Detective Boys investigate a warehouse rumored to hold treasure that appears and disappears. They visit Conan’s home, encountering an unknown person. At the site, Conan finds fresh adult footprints leading to an abacus with an odd number of beads. Climbing a tree, he spots a treasure pile, but the warehouse is empty upon their return. Conan suspects a hidden mechanism, but the boys refute this, noting the two-meter distance between the window and roof is consistent inside and out, and floor markers remain unchanged. However, a marker leaning against the wall has vanished, prompting Conan to reconsider the nature of the warehouse's secrets.
