The Detective Boys utilize yarn from their clothing to traverse a labyrinth, echoing the Minotaur legend, and escape with three hours remaining for the riddle. Conan realizes the solution involves using a spotlight and a black stone to cast a specific shadow that reveals the treasure's location. Tokei and the boys unearth a large pile of gold alongside a photograph of an elderly man and his granddaughter. The narrative discloses that Tokei, who previously served the old man linked to yakuza activities, is actually Yuriko's father.
