404

The Detective Boys parallel the legend of the Minotaur and Theseus by using the yarn from their clothes to navigate the labyrinth. Eventually they find their way out with 3 hours left to solve the riddle. Conan has a revelation and uses the spotlight and the black stone to cast a shadow which leads to the treasure. Tokei and the Detective Boys dig up the treasure and find a mountain of gold and a picture of the old man and his granddaughter. It is then revealed that Tokei, who served the old man, who was apparently involved with the yakuza, is Yuriko's father. (Source: Wikipedia)
