Case Closed: The Time Bombed Skyscraper, known as Detective Conan: The Time-Bombed Skyscraper (名探偵コナン 時計じかけの摩天楼, Meitantei Konan: Tokei Jikake no Matenrō) in Japan, is a 1997 Japanese animated feature film directed by Kenji Kodama. It is based on Gosho Aoyama's Case Closed manga series and featuring detective Jimmy Kudo. The film takes place between episodes 54 and 55. Funimation released the film in North America.

Mortimer Cornhouser, a wealthy heart surgeon, is murdered in his own home, bludgeoned with a miniature statue that was left behind. Also at the scene is an unnatural bloodstain on the floor near the body. He left a dying message using his blood to type the keys on his computer’s keyboard: JUN. The suspects are Mortimer’s wife, Mina, his son Magnum, and housekeeper Manami Goodsbe. When Richard wrongly accuses Mina on the grounds that “JUN” in Japan is “Minazuki” and Mina was born in June, Conan tranquilizes him.

Conan uses Richard’s voice to explain that the killer snuck up on Mortimer and bludgeoned him. The victim turned around and was struck again, causing his hand to brush the keyboard to the ground and accidentally switch it to hiragana. Barely alive, Mortimer typed the message “JUN” but when the facts come in play, reads "Ma-Na-Mi” for Manami Goodsbe, revealing her as the killer. As evidence, blood is found on Manami’s sock; she removed her footwear to reduce the chance of being caught when she snuck up on Mortimer, explaining the unnatural bloodstain found at the crime scene. Manami confesses, stating Mortimer was drunk when he performed surgery on her husband Kevin, who died as a result. She altered her identity and gave herself a Japanese name knowing Mortimer would hire her and today is Kevin’s death anniversary. Manami is arrested.

The next day while sorting mail at Dr. Agasa's house, Conan finds an invitation addressed to Jimmy from Leo Joel, a famous architect. Jimmy calls Rachel using his voice-changing bowtie and asks her to go in his place. Rachel agrees, on the condition that Jimmy goes to see a movie with her on Saturday at the City Center Tower. She explains how Saturday is May 4th, Jimmy’s birthday, and she will surprise Jimmy with a red polo shirt when they meet. At the tea party, Professor Leo Joel introduce himself and proposes a small riddle for Richard to solve; it ends up being solved by Conan instead. Joel makes a subtle comment about architecture and the people involved in the field who are only chasing a paycheck.

That morning, Conan receives a call from a strange man asking for Jimmy, who has recently stolen C-4 explosives and challenges him to a game of cat-and-mouse. Conan accepts the challenge, and the mystery caller gives him clues leading to bombs hidden all over Beika City.

Conan finds, intercepts, and destroys all of the bombs, injuring himself in the line of fire while transporting one out of harm’s way. He notes that the location of the bombs were or near structures that professor Joel designed. On one occasion, members of the Junior Detective League received a toy plane which is actually rigged with explosives from the bomber. Amy remembers the man having a sweet scent emitting from him, wore a long jacket, had a beard and wore sunglasses but is likely a disguise.

Some of Professor Joel’s projects are burned to the ground, including the Kurokawa, Mizushima, Yasuda, and Akutsu households. Professor Joel is interviewed as a precaution. Inspector Meguire recalls a case where Jimmy Kudo was called to assist and deduced that a city councilman fatally struck an office worker while under the influence; his son attempted to take the blame instead. The councilman was a supporter for one of Professor Joel’s projects. With the councilman arrested, support stopped, but Joel holds no grudges. While transporting a bomb to a safe location, Conan notices the timer has stopped. He backtracks his steps pointing out the park nearby which has English style gas lamps nearby.

After stopping another round of bombs on the city’s railroad loop line, Conan visits Professor Joel once again to investigate, viewing a perfectly symmetrical model project. He notes the similarities between the gas lights near the park and the one in the model. Seeing the connection between the arson and bombings, Conan understands the truth of the matter.
