File 001 - The Heisei Holmes

At a party in a mansion, high school detective Shinichi Kudo solves the murder of the host's wife. He reveals to Inspector Megure that the wheelchair-bound host is the killer and that his broken leg healed weeks ago. The next day, on the way to school, the newspapers and TV reporters are all talking about Shinichi's latest case and his childhood friend Ran Mouri is upset at him for once again taking business away from her father, a private detective. The two later go on a date to Tropical Land, as Shinichi promised they would if Ran won her karate tournament. While there, Shinichi spends a lot of time talking about his idol, Sherlock Holmes, and even guesses that a woman in line is a gymnast (because he could see marks on her thighs when the wind blew up her skirt) as a demonstration of Holmes' deduction style. This upsets Ran a little, as she was looking forward to a day with just Shinichi. On the roller coaster, a man named Kishida is mysteriously beheaded in the tunnel. The suspects are the victim's girlfriend Aiko, their two friends Hitomi (the gymnast) and Reiko, and two mysterious men in black. After Inspector Megure and the police arrive, they discover a bloody knife in Aiko's bag and arrest her.

However, Shinichi explains that a woman wouldn't have the strength to decapitate someone with just a knife. He then explains that the killer used an object like a purse or a backpack to escape the ride restraints and wrap a wire around the victim's head while in the darkness of the Mystery Coaster's tunnel. After tying the wire around the victim's head the killer tossed a hook attached to the other end onto the roller coaster's track, beheading the victim using the coaster's speed and movement.

Shinichi concludes the murderer is Hitomi, as her expertise as a gymnast makes this feat possible. Shinichi proves her guilt through two crucial pieces of evidence:

1. Hitomi's necklace (the murder weapon) is missing after the end of the ride.
2. Hitomi has a tear-trail on her face that runs horizontally, which is impossible unless she were crying during the course of the ride.

Hitomi breaks down and admits that Kishida was her boyfriend in college, but he dumped her for Aiko, so she decided to kill him at the same place where they had their first date.

While consoling Ran, who was upset by the crime, Shinichi sees one of the men in black headed somewhere and decides to follow him. He tells Ran to go home without him and Ran has a strange feeling she will never see him again. Shinichi spies on the man in black making a blackmail transaction with a company president. Distracted by the scene, the other man in black hits Shinichi from behind, knocking him nearly unconscious. Before they leave, the men in black give Shinichi a "new poison" that leaves no trace behind in the body. As Shinichi's body burns he thinks of Ran before finally losing consciousness. When he awakens, he has been found by security guards who refer to him as a "boy". The last panel reveals that Shinichi now has the body of a 6 year old.

Company President's Daughter Case

Characters introduced

Conan Edogawa
	7 years old Shrunken form of Shinichi

Kogoro Mouri
	36 years old Ran's father Detective Mentioned in Chapter 1

Hiroshi Agasa
	52 years old Engineer / Inventor Shinichi's old family friend

File 005 - The Other Perpetrator

Shinichi is found by security, and is taken to an onsite medical facility. When he tries to explain who he is and what happened with the transaction, he's laughed at. Then Shinichi realizes he shrunk, and makes a quick escape out the window, where he's chased by dogs.

After escaping from the dogs, Shinichi goes home, but can't open the latch because he's too short. Then Professor Agasa, his neighbor, blows up part of his exterior wall, and soon arrives coughing on the street. Shinichi then convinces him of his identity, by correctly identifying that Agasa had just come from Cafe Columbo.

Agasa lets Shinichi inside his house, and Shinichi puts on a set of his old kid clothes. While discussing what to do, Ran barges in, and Shinichi quickly hides behind the desk in the library. Ran finds him, and he has to create a new name, so he picks Conan Edogawa, which he got from the books on the shelf he's leaning against. (Conan from Arthur Conan Doyle and Edogawa from Edogawa Rampo.)

After Agasa asks if Ran can take care of Conan, Ran agrees. Ran takes Conan home, and during their conversation, confesses to Conan she likes Shinichi, and has for a long time. When they arrive at Ran's home, the Mouri Detective Agency, Conan is about to tell Ran the truth, but is interrupted by Ran's father Kogoro. He quickly informs Ran that he has a client, hails a cab, and hops inside, only finding out after the cab started moving that Ran and Conan joined him.

At the client's house, Kogoro is told that the master's daughter, Akiko, was kidnapped by a man in black earlier in the day. Conan soon realizes that the butler, Asao, was behaving weirdly, and quickly gives small hints to Kogoro, and Kogoro soon informs them Asao was the kidnapper. After Asao confesses, a phone call arrives from a man claiming to have kidnapped Akiko, and Conan realizes that the girl was kidnapped from her first place of confinement by someone unrelated.

Akiko is heard on the phone, and gives a hint about being in a school equipment shed and being able to see a large chimney out the window. Conan then gets on a dog and begins looking for her.

Conan realizes only five schools in the immediate area fit the requirements for the hideout. He then visits them, but doesn't find Akiko. Then he sees a large skyscraper, and realizes that the side view makes it look like a chimney. He locates the school where the building can be seen from that angle, and goes to confront the kidnapper.

The kidnapper is about to kill Akiko, but is stopped when Conan comes. The dog with Conan, Jumbo, attacks the kidnapper, and Conan begins untying Akiko. The kidnapper scares off Jumbo, and prepares to kill Conan. Conan's attempts at self-defense are to no avail, and the kidnapper proceeds to beat him up.

Then Ran comes, saves Conan, and incapacitates the kidnapper. After the others arrive, it's revealed that Jumbo left with one of Akiko's shoes. He went home, where her father recognized the shoe, and followed them to the school. Akiko then reveals that the entire kidnapping was a hoax, orchestrated by herself and Asao, who she forced to help.

Mr. Tani then punishes Asao by making him plan for a week's vacation in Australia for Akiko and himself. The kidnapper is arrested.

On the way home, Conan reflects on the events of the case, and wonders how he'll be able to catch the men in black in the form of a child. Ran asks Kogoro if Conan can stay, and he agrees.

Bloody Idol Case

Character Introduced

Yoko Okino
	21 years old Pop Idol

Gadget Introduced

Voice-Changing Bowtie
	Grants ability to imitate voices

File 009 - An Unfortunate Misunderstanding

Three days after the initial shrinking, Conan wakes up to Kogoro's drunken rambling about Yoko Okino, his favorite pop star. Conan goes to Agasa's house out of sheer irritation. He speaks with Agasa about Kogoro, about Ran, and receives the Voice-Changing Bowtie. Conan likes the bowtie, but he also asks for another gadget, one that'll let him subdue criminals, and Agasa promises to look into it. Agasa also tells Conan that if the Agency needs more cases, then Conan needs to work behind the scenes to make Kogoro a famous detective.

Conan goes home, and Kogoro soon wakes up to watch Yoko on TV. Suddenly, someone rings the doorbell. Kogoro tries to shoo them off, but soon realizes who it is: Yoko Okino herself! Kogoro rushes off to make himself look nice, and invites Yoko and her manager, Mr. Yamigishi, inside.

Yoko informs Kogoro of a stalker problem, involving prank calls, sneaking into her room, and being chased. Kogoro promises to help, and after getting an autograph, prepares to go to Yoko's apartment for more info. Ran and Conan tag along, too.

Upon entering Yoko's apartment, a corpse is found in the living room, stabbed in the back. Ran calls the police, and soon Inspector Megure arrives. Conan inspects the scene, and notices that the heat is up really high, only one chair is upright, and there are traces of water on the floor.

Yamagishi slips and takes hair from the corpse's hand and hides it, though only Conan notices. Conan soon finds an earring under the sofa, and uses the bowtie to inform Megure. Yoko identifies it as the property of her rival, Yuko Ikesawa.

Yuko is called in, and when she starts acting like she owns the place, Conan realizes she's been there before, and quickly points it out. Yuko confesses to being the stalker, as she wanted to ruin Yoko's career, but says she wasn't the murderer.

The victim is identified, and Yoko confesses that she knew him, as he was her former boyfriend. She claims that he broke up with her, and that she didn't kill him.

Conan finds a dent in the floor, and kicks an ashtray into Kogoro's head, knocking him out. Conan imitates his voice and informs everyone that it was suicide, not murder. The knife was frozen in ice, and the victim jumped off the chair onto it. The ice melted from the heat, but the knife made the dent. Conan also proves that it wasn't murder because the hair Yamagishi took wouldn't be in the victim's hand if it was murder.

A diary is soon found, clearly outlining the motive was that the victim wanted Yoko back, and committed suicide when he thought she had jilted him completely.

Later, Ran tells Conan how much she misses Shinichi, and Conan calls her that night, mimicking his real voice with the bowtie, and reassures Ran that he's fine. He does not tell Ran how much he loves her, resolving to tell her after he comes back to being himself.
