Case

Situation

Part 1

The Detective Boys meet Nanami Kyoudou, whose grandfather, Seitarou Kyoudou is the one who built "The Black Tower", rumored to have no entrance and treasure hidden within. Later, they visit her house, where Nanami Kyoudou's mother, Momoe Kyoudou is apparently pushed off of the Black Tower.

Accident?
	Location: Black Tower Victim: Momoe Kyoudou Age: 38 Years old Cause of death: Fall? Suspects: Nozomu Kyoudou, Tsutomu Kyoudou, and Kensaku Nagase Momoe Kyoudou's body is found near the tower after her scream. Did she fall from the tower or did someone push her?

The Detective Boys, now even more determined to find an entrance, search the house, which is filled with different illusions. Then, Ayumi and Haibara needs to use the restroom. But after Haibara tells Ayumi to go ahead, she accidentally falls through a secret passageway hidden behind a mirror in the bathroom. Ayumi immediately alerts the boys about Haibara's disappearance, who begin investigating the restroom; consequently, Conan notices that there's wind coming from the mirror, but can't gain access into the passageway behind it. Mitsuhiko alerts Conan that there's a storeroom next door, so convinced that there's another entrance, the Detective Boys run next door to search the storeroom. There, they discover two mirrors: a big one connected to the wall (though appears to be leaning against it) and a smaller one sitting on a desk. While checking the smaller mirror, Ayumi notices that it is covered with the same heavy perfume Momoe Kyoudou was wearing, accidentally flips the mirror, and suddenly, the big mirror Conan was investigating slides down to reveal an entrance covered with masking tape. Through a small argument, Mitsuhiko and Genta accidentally fall through the passageway, leaving Conan and Ayumi alone. Conan asks Ayumi to stay, but she is determined to go with him to find Haibara, so holding hands, they go through the masking tape together.

Resolution

  Show spoilers »

It was an accident. The victim, Momoe, had mistaken the description of the button leading to the treasure. In the Japanese language, "aoi" means blue, but Tsutomu Kyoudou had described the button as "ao" which can mean blue or green, in this case, green. Momoe had been surprised by the hologram that came when the blue button was pressed, since she was expecting treasure, and she fell. The treasure had been revealed to be a hologram of beautiful colors on the inner walls of the tower of darkness. This tower was supposed to be for Tsutomu to remember his childhood dreams and take over the family business.
