136

The Detective Boys are on a camping trip but Dr. Agasa forgot the tent. They wander to a castle owned by Masuyo Mamiya, meet Katsuo Tabata, Mitsuru Mamiya, Takahito Mamiya, and learn that there's a secret treasure somewhere inside. Conan finds a clue to the treasure and enters a secret passage but is attacked by an unknown assailant. The group searches for Conan but stop to eat dinner. It is there that Mitsuru tells them about the tower that burned to the ground; Mrs. Mamiya, her friends, some servants, and Mutsumi Nishikawa, one of Masuyo's maids are among those who died in that fire. A rumored curse was placed by Mrs. Mamiya with fatal consequences to those who went near the tower. As such, Mitsuri's assistant went to investigate and starved to death after becoming lost in the forest. Agasa is about to call the police to investigate but is knocked out by the culprit.
