It is an old building with five floors. The bottom two floors are for shops, and the top three floors are for residences. There is also an open-air rooftop at the top, surrounded by a half-height railing to prevent residents from stumbling and falling off when climbing to the top.

At this time, on the railing near the side of the street, a quilt was hanging on it, fluttering in the wind.

This is a very common and lively scene, but there is one thing that is very interesting - under the quilt, there is obviously a large bulge, and it seems to be covering some kind of long object.

As for what is covered...... Don't bother guessing at all.

Because it was not five seconds before the white tree raised its head, a figure slipped out of the quilt without warning and fell suddenly.

The white tree took half a step back, watching it slam into the front cover of the police car parked on the side of the road, smashing with a loud, dull thud.

The one who fell was a middle-aged man, he was fat, his eyes were wide open, and his face was only frightened, and the person was obviously dead.

But the cause of death did not appear to be a fall - the body did not look new, and it was estimated that it had been dead for a while. In addition to this, a deep strangulation mark could be seen on his neck, and a dagger pierced through the pocket of his blouse, piercing deep into his heart.

Falling, suffocating, puncture...... Take out any one, they are all lethal factors, plus the corpse has a few loops of rope wrapped around its waist, and the end extends a few meters long, no matter how you look at it, this person is not killed by accident.

When such a big incident happened, the whole street was alarmed, and the crowd either stopped and gathered carefully, or poked their heads out of the windows to watch from afar, and the scene was a little chaotic for a while.

Bai Shu's gaze swept around the corpse, but he couldn't find what he was looking for, so he looked up at the rooftop again.

When he saw the translucent object the length of a small arm, his face sank.

…… The body has fallen, what are the souls still doing hanging so high on the railing, they have already died once, and they can't fall down again, what's wrong with the corpse martyrdom! It is really unconscionable to leave his own corpse.

He criticized a few words in his heart, and he was not very happy to withdraw his gaze, and was forced to find his way to the rooftop.

At this time, several people rushed out of the store of Okonomiyaki, and Sakata, who was frightened in the driver's seat of the police car, finally came to his senses and kicked open the slightly deformed door and rushed out. A group of people surrounded the body on the front lid of the car, preventing passers-by from approaching.

Three detectives and a policeman quickly entered the investigation mode, Conan glanced at the corpse a few times, suddenly remembered something, turned his head around, and seemed to be looking for something.

When he saw the white tree that was also walking to the side of the car half a street away, the corner of his eyes jumped, revealing a speechless expression that was really like this, and asked, "What happened?" ”

Bai Shu put on a face of innocence with a clear conscience, "I don't know, I just crossed the road when I saw this old brother fall from it." He pointed to the rooftop.

"Above?"

Conan and Hattori followed his direction, and when they looked up at the same time, they found that there was actually someone on the rooftop, who was holding on to the railing, looking down, and his position was slightly backlit, and he couldn't see his face clearly.

"Didn't you run away after committing the crime? How dare this bastard defy the Osaka police! ”

Hattori was furious, twisted the brim of his hat back, and walked straight to the nearby stairs. Conan also chased after him, and his short legs were no slower than Hattori's Heiji.

Of course, there was no elevator in this old-fashioned residential building, and Shiraki looked up again, looking at the soul above his head that not only climbed back to the railing, but also locked himself tightly on all fours, and felt that he could not expect it to fall off on its own, so he had to sigh and reluctantly go up the stairs.

Mori Kogoro and Sakata originally intended to catch up, but as more and more passers-by gathered, they hesitated a little and decided to stay and maintain order.

……

When Shiraki arrived on the rooftop, Conan and Heiji Hattori had already surrounded the "murderer" in front of the railing, and unless the "murderer" had the ability to jump from the roof of one side of the street to the roof of the other side of the street, he had no way to escape.

However, this uncle with a U-shaped hairline doesn't seem to have any intention of running away. He just waved his hand vigorously and explained:

"It's not me! I am the owner of the tea shop on the second floor of this building, and someone suddenly called me just now, saying that there is a strange person on the rooftop, let me come and see, I just came up! ”

Hearing this, Shiraki glanced back at the door leading to the rooftop.

The handle of this door is not the closed handle commonly used on rooftops, but the grip type - the kind that can open the door when you turn down.

Thinking of the long rope attached to the waist of the corpse, and then thinking of the almost boss who was shouted to "throw the corpse", this little trick is not difficult to understand: about to kill the person, hang the corpse outside the railing with a rope, and the other end of the rope is tied to the doorknob.

Although I don't know why such a swollen quilt that is still dripping blood has not attracted anyone's attention for a day, and I don't know how this rusty door and slender hemp rope can withstand the burly physique of the deceased uncle, but ...... Theoretically, this ploy is indeed possible.

And what is theoretically feasible, in this small world, no matter how bad the probability is, as long as certain conditions are met, it can basically be triggered 100% to achieve.

After a brief investigation of the scene and questioning, the two young detectives quickly deduced the truth, and they finally let go of the teahouse owner who promised to provide communication records, and after carefully inspecting the rooftop railing, they led the people back to the police car.

When he stepped down the last step, Bai Shu's notebook suddenly reacted, and he touched it out and saw that there was an extra black name on it: Gangqi Chengjiang.

Black represents the dying person, Shiraki has never seen her, but she is clearly easy to find.

- In the crowd of onlookers, there was a long-haired woman with a frightened expression, her whole body trembling in it, and her mouth was still making strange and meaningless trembling sounds like "Ah......" from time to time, no matter how you look at it, it is out of place with other passers-by.

After a second or two of Shiraki noticed her, the woman finally recovered from her fright and turned away sharply, her high heels making a sharp crunch on the concrete road.

What would be the first reaction when you see someone running wild at the scene of the crime?

The reactions of the two detectives were surprisingly consistent, one large and one small, and the two figures chased after each other, but by the time Heiji Hattori and Conan finally squeezed out of the crowd, the black long straight woman had already sat in a taxi on the side of the road, the door was closed, the driver stepped on the accelerator, and the car sped away.

“…… What a run! Hattori Heiji looked at the back of the car unwillingly, "There is definitely something wrong with this person!" ”

"It's okay, I wrote down the license plate number." , Conan is not in a hurry, because at the moment, he has more interesting things.

"Just now on the rooftop, when you deceived that uncle, you used the word 'murderer', it sounds a bit like a serial case." , Conan pushed his glasses, and Hattori stared at the reflection on his eyes and froze.

At this time, Bai Shu made up again: "You said before that case had nothing to do with us, but now, we are completely involved, and the body almost hit me." ”

"......", it's far from it! Don't think I didn't see you coming across the street!
