Situation

The Case

While Kogoro and the group are watching a news report on a recent bank robbery, Amuro stops by with sandwiches from the Poirot after finishing his part time job for the day. After commenting on the robbery, Amuro reveals that he wants the scoop on Kogoro's newest case request after deducing from Kogoro's appearance and habits that Kogoro had a case. Kogoro gets a text from the client requesting that Kogoro switch the meeting location to the Café Columbo, and Amuro goes with them after changing out of his work clothes.

At the Columbo, Kogoro explains to Amuro the request was to find the locker a key belongs to. The client fails to show, so Amuro, Kogoro, Conan, and Ran go back to the Mouri Detective Agency to make sure the client didn't actually turn up there instead. When Amuro arrives at the agency, he and Conan notice someone had broken in and appeared to have intercepted the client while they were out. Stepping outside, Amuro explains his deductions to the rest of the gang and that the culprit is hiding in the restroom. Before Amuro can open the bathroom door, a gunshot rings out, and Conan rushes in to find a dead man who apparently committed suicide with a gun and a taped-up crying woman.

Resolution

Show spoilers »

From the evidence that Conan gathered during time at the gas station, he concluded that Kei Kashitsuka's real name is Serina Urakawa, a bank employee where the recent robbery took place. Serina isn't Kenya Shouno's younger sister but is his lover. The name Kei Kashitsuka actually belong to the man that Serina murdered at Mouri Detective Agency, using shoe rope trick to pull the trigger. Her motive is to kill the three robbers that was responsible for Kenya's death and so she tracked down his friend named Kei Kashitsuka. However she stumble across one of Kei's friend (one of the robber) and in self-defense, killed him. After planted several listening devices, Serina heard that Kei will request Kogoro to search for the rest of money's location and so she ambushed him at the agency. She used stun-gun on him, switched their belonging and used the trick described above to make it seem that she's a victim.

Conan then furthered his deduction by saying that he know that Serina will commit suicide after she murdered the third robber. Serina then accepted his condition and so he told her that the third robber's true identity is Takayo Tegawa. From the footage and information from Serina, Conan concluded that the third robber's true identity is Takayo Tegawa as both Toyokita and Furiya are right-handed (Tegawa is the only left-handed person). Tegawa's suspicious actions are also serve as an evidence, she bought beef-bowl rice to change the 10,000 yen bills number and she switched off her phone to prevent the police to find her. After the deduction Serina agreed to turn herself in but she said that one thing is wrong, she only took 2 guns from Kei Kashitsuka's hideout, alerting Conan that the third one must still in Tegawa's possession. They were later abducted by Tegawa, who used Conan as a hostage to intimidate Serina. Since Tegawa held Conan's wrist tightly, he was unable to use the stun-gun wristwatch.

Carjacking

Location:	On a street near Takayo Tegawa's house
Hostages:	Conan Edogawa and Serina Urakawa
Culprit:	Takayo Tegawa
Takayo Tegawa burst into Serina's car and took Conan as hostage to force her to drive to a place where there was no one around.

Fortunately, Subaru's car arrived at the scene just as they started driving away. According to the tracking device, Haibara figured out that Conan was inside that car. They informed Kogoro about this information, and Amuro then noticed their car running pass them on the other side of the street. He increased the speed to catch up with the trio, and crashed his own car into theirs in order to stop it. Masumi, who had been closely following him this whole time, ran her motorcycle up and knocked off the robber. After everything was over, Vermouth arrived at the scene and gave Bourbon a call, asking him/her if he/she would keep his/her promise with her. Subaru, Amuro, and Masumi all received a phone call at the same time Vermouth dialed leaving it unclear which one of the three is really Bourbon.

Manga to anime changes

Main article: List of differences between the manga and anime

Due to the fact that these four episodes were adapted from only five manga chapters, to fill in the timing, the anime version of the case was included with a few additional scenes that were not from the original manga. One of such scenes showed Subaru waiting for Agasa and Ai inside of his car in front of Agasa's house, before they started moving. He was shown secretly listening to something with a device, and immediately hid it when the two people came out. It was never explained what exactly he was listening to. Aside from this, there were also some small additional dialogues during the whole case that weren't originated from the manga.
In the manga version, right before Amuro crashed his car, Amuro told Kogoro to put on his seatbelt in the backseat. In the anime version, Kogoro was already wearing his seatbelt, so Amuro told him to stay as he is.
Color changes:
- In the manga Kei Kashitsuka's hair is brown, while in the anime it is black.
- In the manga Subaru's car is white-colored, but it is changed into red in the anime, which may be a possible reference to Shuichi Akai. (Akai means red in Japanese)
- In the manga Vermouth's cellphone is black, but it is changed into white in the anime.
- In the manga Amuro's cellphone is white, but it is changed into black in the anime.
