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. Koshimizu confesses she was searching for the detective whose inadequate investigation led the police to suspect her friend as a murderer, prompting her friend's suicide. That detective turned out to be Tokitsu, whom she murdered in revenge.

The trick to secret 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.
