Episode 1071: Yusaku Kudo's Detective Show (Part 1)
Scenario: Yusaku emerges from the Metropolitan Police Department and is approached by a TV reporter. The reporter's purpose was to report on the exoneration of the Phantom Thief Kid from a certain case, so he asked if his visit to the Metropolitan Police Department was to confirm the exoneration. However, Yusaku came to the Metropolitan Police Department to give advice on another case. During the past month, there had been three cases of what appeared to be serial locked-room murders. However, all three victims were completely unconnected, and the methods of murder were different. So, Yusaku was asked for his opinion, "Is it the same crime?".
Yusaku, who does not know who the culprit is but has solved the mystery of the locked room, will appear in an episode of "Emergency Live Broadcast! Serial Locked Room Murder Case Completely Unraveled! on Toto TV on the weekend. He declares that he will demonstrate his reasoning, and he leaves a message for the reporter's question, "A word to the Phantom Thief Kid."
On the day of the live broadcast, Yusaku gets food poisoning from something he ate at an Italian restaurant last night and falls asleep. Conan is summoned by Yukiko, who disguises herself as Yusaku, and uses a voice-over machine to voice her and present his theory.
After exiting the police headquarter and being interviewed by reporters, Yusaku Kudo reveals that he is going to do a live broadcast solving three locked room murders that took place on the last days, but 3 days later, on the day of the show, Yukiko Kudo tells Conan that Yusaku suddenly got food poisoning and has a stomachache, and that she will disguise as him, and with Conan's help, solve the case. Yukiko reveals details of the murders. The first victim named Atsumi Morita, an apparel company employee, was killed in the bathroom of her apartment after being pushed to the sink and hitting her head with it 20 days ago, the bathroom door was locked and the scene was ransacked, with various bathroom items on the floor. The one who found the body is Saiko Yumekawa, Atsumi's friend, who is known for conducting interviews using a pink mic. She is also the reporter coming for the live broadcast.
The second murder took place 10 days after the first murder. The victim, Taiji Kiryu, a permanent-part time worker, was stunned with a stun gun and later strangled with a rope in the entrance of his apartment. The scene was also a mess with garbage, bags and used ramen cups. It seems he fought back while being strangled and the culprit's skin got in his fingernails.
The third and last murder was done the next day after the second murder. This time, the victim Koretsugu Kanzawa, a baker, was stabbed on the abdomen with a knife in the kitchen of a house in Haido. Like the previous murders, the scene was also a mess with multiple kitchen objects on the floor, including the knife used as weapon.
Yusaku deduced that the three murders were locked rooms and that they were locked from inside. When Conan goes to Yukiko's room, it turns out Yukiko also feels bad and it's revealed that she got food poisoning too. But suddenly, Kaitou Kid (disguised as Yusaku) appears to "repay the favor" that Yusaku did by clearing accusations made against him. Conan and Kid only have 10 minutes until the TV staff arrives to the Kudo household.
