Plot

Outbreak

Sera asks Ran if she can come over to talk to Conan. Once there, she learns Conan is at Agasa's with the Detective Boys and the fact Conan is with Kogoro on every case. They are soon interrupted when a gunman strapped with bombs and three hostages are brought into the agency.

Bombing Threat

Location: Mouri Detective Agency Victim: Kogoro Mouri, Ran Mouri, Masumi Sera, Tamami Mitsui, Shinobu Yuchi, and Sumika Nihei Suspects: Isao Sawaguri Isao Sawaguri came to the Mouri Detective Agency and brought together three female novelists he believe are responsible for his younger sister Miku's death the previous month. Isao threatens to blow up the Agency unless Kogoro reveals to him the truth about his sister's death and reveals her murderer.

The gunman, Isao Sawaguri, demands Kogoro to determine which of his three hostages killed his sister.

Suicide? (Past)

Location: Furitsukaya Ryokan Victim: Miku Sawaguri Cause of death: Loss of blood through slit wrist Suspects: Tamami Mitsui, Shinobu Yuchi, and Sumika Nihei According to newspaper reports, novelist Miku Sawaguri committed suicide at the Furitsukaya Ryokan a month previous to Isao's threat on the Mouri Detective Agency. Despite the reports, Isao is convinced that his younger sister's novelist friends are responsible for killing Miku.

Conan calls Ran to ask who she was spotted walking with. Sera answers and pretends to end the call, allowing Conan to eavesdrop on the situation. Conan learns the case of Sawaguri's sister, Miku Sawaguri, was concluded to be suicide when she was found with her wrist slit and her ryokan room locked. Agasa and the Detective Boys leave to interview the local neighborhood association who were at the ryokan during Miku's death. Conan gradually learns more about the case from information spoken by Sawaguri, the media, and the Detective Boys. Sawaguri then realizes Ran's cellphone is still connected and prepares to shoot Sera until Conan speaks with his voice changing bow-tie as Shinichi Kudo.

Sniping

Sawaguri, pleased to have another detective to find the culprit, obeys his requests to take pictures of the hostage's books which were autographed by Miku. During the course of the investigation, the authorities lose the chance to snipe Sawaguri after Ran closes the curtain as she believes Shinichi can find a solution to prevent any deaths. Miku's blog post reveals her last three visitors were from an elephant, a fox, and a rat. Conan explains the animals were based on the hostage's professions: The elephant is Sumika Nihei, due to her husband's seal designs is similar to an elephant's tusk; Shinobu Yuchi is the fox since she is a bakery and her food is colored like a fox's coat; and the rat is Tamami Mitsui whom is a stonemasonry which is gray like a rat's coat. In response, Sawaguri prepares to kill Mitsui.

Release

Conan declares Mitsui is innocent since she was witnessed leaving Miku's room; Sawaguri inferred the culprit crossed over from the balcony and left by his room. As for Miku's death, Conan explains she was mimicking the suicide of the main character in her book. Sawaguri becomes distraught as a result and is taken in by the authorities.

Later, Conan reveals his previous deduction was a bluff and that Miku was murdered by Yuchi, due to the fact Mitsui left the room with Yuchi's slippers revealing Yuchi was still in Miku's room after she left. As evidence, Yuchi's book reveals it had been sandpapered to clean off Miku's blood. Yuchi confesses and reveals Miku took all the credit on the book they collaborated on motivating her for revenge.
