Traveling back thirty years to Conan, intercepting Princess Eri

"It's a common trope in movies and TV dramas," Lin Xiuyi explained casually. "Whenever a character says something like, 'After I finish this job, I'll retire and get married,' or 'After I finish this job, I'll go home and be with my family,'..."
Ultimately, they usually run into trouble, either sacrificing themselves or encountering an accident; very few manage to achieve their wishes smoothly. That's why people call this kind of talk 'setting a flag' (or 'making a promise').

"what?!"

Inspector Megure's expression changed instantly; he slammed on the gas pedal, his voice filled with anxiety.
"You mean Master is in danger? Could something happen to him in this case?"

Hey! Drive carefully!

Lin Xiuyi quickly grabbed the handrail and said with a speechless expression,

"I already said this is just a convention in movies and TV shows, not a law in reality, so how can you take it seriously?"

"Officer Morimura is very experienced, you'll definitely be fine. Don't scare yourself, just drive carefully!"

Inspector Megure calmed down a little and quickly slowed down, but the worry on his face did not diminish at all.

Seeing his nervous expression, Lin Xiu felt a subtle emotion welling up inside her.

Although he said it was just a movie trope, vague memories of Detective Morimura from his past life suddenly flashed through his mind, and he vaguely felt that this case might not be so simple after all.

The police car sped through the traffic, heading towards Associate Professor Yamada's house.

……

As dusk settled, sparse streetlights began to illuminate the streets of Tokyo.

In the residential area near Associate Professor Yamada's house, Officer Morimura walked slowly along the sidewalk alone, clutching a photo of a samurai sword in his hand, his brow furrowed.

This knife went missing from the home of the first victim, Dr. Sato, and was also the murder weapon used to kill Associate Professor Yamada. Finding it might lead to the capture of the killer.

"Did you see anyone carrying a samurai sword like this last night? It was about this long and had a black scabbard."

Officer Morimura stopped an elderly man walking his dog and handed him the photo.

The old man squinted for a while, then shook his head: "Never seen him before, young man. This area is quite quiet at night, there aren't many strangers around."

He then asked the clerks at the convenience store on the roadside, the office workers who had just returned home from get off work, and the children playing downstairs, and the answers he received were surprisingly consistent.

No one had seen the knife, nor had they noticed any suspicious persons.

"Looking for a needle in a haystack is definitely not going to work!"

Officer Morimura shook his head dejectedly and rubbed his aching shoulders.

He has been wandering around this area for more than two hours since the afternoon, and his legs are almost broken, but he hasn't found a single clue.

The last glimmer of light on the horizon disappeared, and all the streetlights came on, casting his shadow long.

Officer Morimura stretched and prepared to meet up with Officer Matsumoto first, hoping they might have made a new discovery.

Just then, his gaze swept across the intersection not far away, where a black sedan was parked, its lights off, looking somewhat out of place in the dim night.

"Let's ask one last question."

Officer Morimura muttered to himself as he walked toward the car, thinking that the owner might have happened to pass by last night and seen something.

……

Meanwhile, Inspector Megure drove his police car to the vicinity of Associate Professor Yamada's house with Hayashi Shuichi in tow.

As soon as I turned into the neighborhood, I saw a uniformed police officer going door-to-door asking about the situation.

"Excuse me, where is Inspector Morimura? We're from the First Investigation Division, here to support him," Inspector Megure asked, rolling down his car window.

“Inspector Morimura is on another street,” the officer replied. “To broaden the scope of the investigation, he had us split up, each taking charge of a section. He went to the street to the east.” “Understood. Be careful on your own and stay safe.”

Inspector Megure gave a brief instruction, then immediately turned the car around and sped off in the direction the officer had pointed.

Lin Xiuyi leaned back in the passenger seat, her gaze sweeping across the street outside the window, her mind constantly sorting through the clues in the case.

Unfortunately, there's still no clue.

……

Officer Morimura had already walked up to the black sedan.

The driver's side window was half open, and he could vaguely see a person sitting inside, but it was too dark to see the person's face clearly.

To his surprise, a low whistling sound came from inside the car. The tune was sad and familiar. Upon closer listening, he realized it was The Beatles' "Let It Be".

This is also a song that Officer Morimura really likes.

Even more strangely, looking through the crack in the car window, the driver seemed to be crying, and his shoulders were trembling slightly.

"Excuse me, sir,"

Officer Morimura knocked on the car window and handed over the photo.

"I'm from the Metropolitan Police Department's First Investigation Division. Did you see a samurai sword like this last night? Around 1 a.m., in this area."

Worried that the other person might not be able to see it clearly in the dim light, he deliberately handed the photo closer, almost sticking it into the car window.

However, the moment the other person saw the photo, their body stiffened abruptly, and the mournful whistling suddenly went off-key and even stopped abruptly.

"Sir, have you met him before?"

Officer Morimura sensed something was wrong and immediately frowned.

Just then, his gaze swept over the passenger seat, where a samurai sword with a black scabbard was placed, and the scabbard looked exactly like the one in the photo!
I'm so lucky today, I actually stumbled upon the murderer by accident?

Officer Morimura's heart tightened, and he immediately became more alert: "Get out of the car and submit to inspection!"

As he spoke, he reached for the car keys, trying to stop the other person from escaping.

But the driver reacted even faster, slamming on the gas pedal almost the instant he reached out.

"Om-"

The engine roared to life, and the car surged forward in an instant.

Officer Morimura's arm was already inside the car window, and he couldn't pull it back in time. He was dragged forward by the car, his feet scraping against the ground with a screeching sound.

"Stop the car! You are assaulting a police officer! Stop the car immediately!"

Officer Morimura gripped the car door tightly and shouted warnings, but the driver seemed not to hear him and continued to press the accelerator.

Pedestrians on both sides of the street screamed in alarm and scattered, while some took out their phones to call the police.

Officer Morimura felt a sharp pain in his arm, and his body was being dragged and swayed from side to side, in danger of being thrown off at any moment.

Seeing that he was clinging to the car door and refusing to let go, a fierce glint flashed in the driver's eyes. He suddenly turned the steering wheel and crashed into the street lamp on the side of the road!
With a loud bang, Officer Morimura's arm was slammed into a street lamp, and a sharp pain instantly spread throughout his body.

He could no longer hold onto the car door, and his body was flung out like a kite with a broken string, crashing heavily to the ground and rolling several meters away... (End of Chapter)
