Sonoko takes Ran and Conan to a marple forest in Gumna to imitate a scene from a popular tv-drama for her new romantic plan involving Makoto. She wants to tied up a red handkerchief, so she can meet up with Makoto there. But unfortunately they discover that other fans of the drama has gotten the same idea and tied up red handkerchiefs themselves. They then meet a man claimed to have inspired the drama by having found a red handkerchief tied to a tree in the same forest and told the writer who used it in the drama. He tells them that he has been asked by a fan to find the original red handkerchief and asks Ran and Sonoko to leave a message in the guestbook at the inn, where the fan is staying. He tells them to sign it Hozumi in katakana. After Ran, Sonoko and Conan follows his request, they decides to go back to the forest, but there they find Hozumi murdered.
