Five p.m., computer company, fifth floor.

"Conan! You little devil again......" Before Maori could finish speaking, Conan had already shot him with a tranquilizer gun, and after a few seconds, Maori collapsed on a chair, and Conan immediately hid behind, picked up the bow voice changer, and began his reasoning.

"What I said just now is actually the result that the real murderer wants to see!" Said the sleeping Maori Kogoro.

"Maori brother? Are you going to start reasoning again? Are you saying that the murderer is someone else? ”

"Yes, when the murderer killed Bob and was about to leave, he turned around and found that the deceased was still alive and left a password, so he saw the meaning of the code, and changed the password left by the deceased on the computer, wanting to blame Larry."

"Wouldn't the real murderer be untraceable?" Officer Twilight asks.

"No, think about it, the deceased had stab wounds on both hands and must have had a lot of blood on his fingers. Ask Officer Twilight to pull out the keyboard and look at the clear blood stains left by the deceased on the keyboard. ”

！！！

At this time, the murderer began to panic and ignored that point!

Officer Twilight pulled out his keyboard and froze, "Really! The keys that leave clear blood stains on the keyboard have NQFFU, and the first letter is not the same as the PQFFU just seen! ”

"Yes, because the murderer and the deceased have the same syllable in their English names, right? Mr. Barry! ”

"Huh?" Barry's face flushed, and he defended himself firmly, "Wasn't the time when Helen heard the screams when Bob was killed?" I was at the hotel with you! ”

"I mentioned the overhead announcement, if you record someone screaming and then periodically make an exclamation for passers-by below to hear, then it can constitute an alibi."

"So how did I make the Chamber of Secrets? You don't have any conclusive evidence, and the computer information is just a coincidence. ”

"Then I'll reveal the secret: after killing someone, the murderer first pressed one end of the long enough rope prepared in advance under the book, then tied a heavy object to the other end, stuck his head out of the window, threw the heavy object into the window on the sixth floor, and went to the sixth floor to fix it. Then, back to the fifth floor, I took out the rope that was pressed under the book, and ran a long, thick hollow steel pipe through the rope to the window. In this way, the rope does not have to come into contact with the window, that is, it does not leave rope marks, and the outside of the steel pipe is smooth and does not leave marks. Then press the rope back under the book to straighten it. Lock the door with the key and go to the sixth floor. Then, the key can quickly slide through the rope to the back of the pile of books, and finally pull the rope back hard. Of course, because the key is relatively small, it can easily pass through the steel pipe, so that the secret room is formed. The proof is the location of the key left at the scene and the steel pipe found in the trash can downstairs, Conan, you take it out. ”

"Yes!" Conan stepped out from behind Maori, holding a steel pipe in both hands, and there were obvious signs of rope friction at both ends of the pipe.

"That's a good idea, but you can't say I did it, and I have proof that Helen heard the screams when Bob was killed. When I came in just now, I took a picture of the scene, please see it. Barry then took out his phone, and there was indeed a photo in the album, "You look at the computer monitor in the photo, although it is a black screen, but you can see that the lower right corner says 'Standby for 51 minutes' When we came in here, it was half past three, so no one moved the computer at 2:40, and this time was just when Helen heard the scream, right, Helen?" ”

"Indeed, the manager is right." Helen replied.

"The time when the computer hasn't been touched is when Bob dies, Mr. Maori, how do you explain that?" Barry was more confident.

"Something touched the computer and activated the computer display that was already standby. In fact, you kill people around two o'clock. Maori Kogoro poured a basin of cold water.

"Hehe, are you saying I can control the computer monitor remotely? Is this possible? ”

"There is something that is everywhere in life, and its propagation has energy." Kogoro Mori explains, "Yes, it's Sonic Waves!" The screams you recorded in advance also have a slight energy, and this kind of computer is inherently sensitive, so your evidence is not valid. If you have any objections, then use the radio and this computer experiment to see? Only you have the key to the radio room on this floor, right? ”

"Officer Takagi, go try it! Manager Barry, please hand over the keys. Officer Twilight ordered.

"No, no. It seems that in front of the great detective Mr. Mori, I can only surrender. Barry finally admitted that he was the murderer, "I can't stand him, he sold some of our company's data to other companies, and we have no evidence that he is undercover...... So, I killed him. ”

"Anyway, let's go to the police station. Thank you, Brother Maori. Officer Twilight leaves the office with Barry.

"Mr. Maori, I can't treat you to this meal."

Hehe, who told you to go to my uncle for making an alibi? Conan sighed in his heart.

The snow outside stopped, and Mori Kogoro woke up.

"Dad, are you awake?"

"Let's go, Lan. Let's go find Miss Yoko, Miss Yoko......"

"I don't think he's woken up yet!" Conan was speechless.

Belltron watched as Conan finished solving a case, but didn't say anything.

Back at the detective agency, it was almost six o'clock.

As the sun sets, the crimson color is warm. Unbeknownst to anyone, in a dark corner of the street below, a silver-white haired man in black was leaning against the wall on the phone.

"Edogawa Conan, Edogawa Hakuzu, these two people, you go and investigate, the other side of the flower." There was a murderous aura in his voice, and his eyes flashed with a sinister smile.

"Yes, master."

The first darkness of the evening ruined the time of the whole world. After all, darkness came, and time died.

The Man in Black finally left the street. The black trench coat blended in with the darkness, as if the endless darkness was just a corner of the man's clothes.

The bleak moonlight sprinkled the land, and the lonely streets gave birth to countless mysterious shadows under the cold moonlight, looking from afar like the flames of the undead, endless.

The bookstore under the Maori office has long since closed, and a black cat meows from time to time inside...... The sound of "...... makes passers-by creep, it seems to be pouring out something, or is it portending something?

Its name is: Watson.

In the basement of Dr. Asasa's house, Gray Yuan suddenly felt a chill.

"Who's around?" Gray Yuan only felt that his scalp was numb, and he smelled a strong breath, "More than one person? ”

"Are they?"
