◄Case 1: Mansion Murder Case►
A man is shot in his locked room during the social gathering held in the mansion. The victim is Manager Yamazaki of Yatsubishi Bank. During the investigation, a high school detective named Shinichi Kudo enters the scene to solve the case.
Case Information
Case: Murder
Victim: Yamazaki
Cause of death: Gunshot wound
Suspects
1. Mansion Owner - Owner of the mansion
- In a wheelchair due to injured leg
2. Guests
Investigation
→ Shinichi says that the room of Yamazaki was locked inside when he was killed.
→ Shinichi states that the only possible entrance into the room was the window.
→ The mansion owner says that there is at least a 10 meter gap between the window and the balcony.
→ Shinichi points out that if the killer used the roof eaves to get closer to the balcony, the gap would be shortened to a mere 2 meters and therefore could be easily jumped across.
Evidence
→ Mark on the balcony where the killer attached the rope with a rod.
→ Absence of footprints below the window implies it was an inside job.
→ Shinichi Kudo claims to have spoken with the killer's doctor.
Deduction
→ Shinichi notes that the killer attached the piece of rod in a rope at the balcony to allow the killer to get back across the window. By using a piece of rod rather than simply tying the rope to the balcony, the killer was able to remove evidence of his method of escape while on the other side of the building.
→ Shinichi deduce that the murderer could be a person who knew the mansion very well.
Resolution
→ Shinichi Kudo points his finger at the murderer, the mansion owner.
→ The mansion owner, being in a wheelchair, then starts to laugh claiming that he's in no position to be able to commit such a crime.
→ Shinichi then grabs a globe and throws it towards the owner who immediately jumps out of his chair to avoid it.
→ Shinichi then says that he's been healed for 3 months as reported by his doctor, which Megure confirms.

Mansion Owner
Motive
The episode did not clearly state the mansion’s owner motive, it likely had something to do with the secret financial dealings the owner had with Yamazaki.
◄Case 2: Roller Coaster Murder Case►
Ran Mouri and Shinichi Kudo go to the Tropical Land, an amusement park, for a date. Their date was cut short when a murder occurs while they're riding the roller coaster. Who is responsible for killing Kishida, and how did they do it?
Case Information
Case: Murder
Victim: Kishida
Cause of death: Decapitation
Suspects
1. Aiko - Kishida's girlfriend
2. Hitomi - Gymnast
3. Reiko - Hitomi's friend
4. Men in Black
Investigation and Deduction
→ Kishida is beheaded while riding the Mystery Coaster.
→ Shinichi examines the tunnel area of the Mystery Coaster and finds a wire with some pearls still strung onto it and a hook at the end of the wire.
→ The killer left a false piece of evidence, a bloodied knife, inside Aiko's purse with the intention of framing her. Shinichi proves this is a fake piece of evidence claiming that it is impossible for a woman to have used enough force to behead someone while on the ride.
→ Shinichi states that 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 deduce that the murderer is Hitomi, as her expertise as a gymnast makes this feat possible.
Evidence
→ Hitomi's necklace (the murder weapon) is missing after the end of the ride
→ Hitomi has a tear-trail on her face that runs horizontally which is impossible unless she was crying during the course of the ride.
Murderer
Hitomi
Motive
Hitomi murdered Kishida because she used to go out with him long before she met Aiko and Reiko in college. Hitomi planned to murder Kishida at the place they had their first date (Tropical Land) using the necklace he had bought for her. If Shinichi didn’t prove the truth behind the murder, Hitomi was planning to commit suicide via drugs after the visit to Tropical Land.
◄Chasing the Men in Black►
Shinichi, suspicious of the two men dressed in all black that rode the coaster, decides to follow them on their way to the outskirts of Tropical Land, leaving Ran behind and telling her to head on home without him. Shinichi witnesses one of the men in the middle of an illegal transaction with somebody and doesn't pay attention to his surroundings. The other man dressed in black knocks Shinichi out from behind. The men, recognizing Shinichi as a detective, give Shinichi an untested poison in order to kill him and leave him to die. However, rather than killing Shinichi, the poison shrinks him down to the size of a seven year old.
