Synopsis

The detective boys were on a mountain forest hike, their mission to locate stag beetles. Later, Conan received a phone call from Ran and Sonoko. They informed him that a burglar had attempted to steal Sonoko’s bag. Because the incident seemed connected to a murder, Conan examined the photograph Sonoko had sent, hoping to decipher the cryptic message within it. While working on the puzzle, he also assisted the Detective Boys in solving one of Professor Agasa's coded challenges.
