After investigating, Conan and Heiji reveal that Shakuren arranged the temple's blood-stained tatami mats so that the stains are hidden by tatami-squares in the bottom of the glass statue-cases positioned at the four corners of the room. Shakuren reveals that the body was Denkyu's mother, who abandoned him eighteen years ago. He reveals that she committed suicide after Shakuren refused to give her back her son, when she could not even recognize which one of the monks at the temple he was.

After a thorough investigation, the culprit is revealed to be the detective of the South, Natsuki Koshimizu. Her real age is 20, and she has pretended to be a school detective to lure them in, complete with using her old school uniform. Natsuki confesses and explains she was searching for the detective whose inadequate investigation caused a massive tragedy.

The owner of the Lavender Mansion (where the Koshien "challenge" was taking place) was a mentally unstable socialitè, who commited suicide by hanging two years ago. Natsuki's best friend Kana Mizuguchi worked as the lady's maid, with Renzo Kouya as the housekeeper; they were seen as possible suspects but were acquitted. Some time later, however, the investigation was re-opened and Tokitsu was the detective in charge, as it was believed that it was a murder; some new tricks had been used in the house, leading to believe that the lady had caught a thief and was killed for it. The top suspect was Kana, and she begged Natsuki to protect her from this "high school detective guy with a weird accent"; she ended up cracking from the pressure and commited suicide by throwing herself into the sea before Natsuki could clear her unfairly tainted reputation. (The thief was revealed to be Tsuchio, whom Natsuki located and forced to pose as a productor.)

Since Natsuki didn't have the detective's name, she went for the guy's gender and accent. The three other school detectives fit in this profile: Junya Tokitsu used an archaic male pronoun for himself (shousei), Heiji Hattori had a thick Osaka accent, and Suguru Hakuba's Japanese was odd since he lived abroads. She confronted Tokitsu first, and he admitted being that school detective but showed no empathy for Natsuki's plight and Kana's death, causing Natsuki to beat him to death with the hammer used in the trick to the locked room.

The trick to the locked room was to remove the window frame and then replace it after leaving. The screws holding the frame in are removed and cut short. The frame is replaced after the murderer exits by simply gluing it back into place with the short screws slid into their corresponding holes so the window looks untampered with. Additionally, when Natsuki lost the screws during the thunderstorm, she pretended to be scared of lightning in order to seek for them without being suspected.
