"The way to solve a case is not only to use the brain, but also to use the feet. Going out of your way to every place is the way to solve crimes. Kaga is doing a good job of this. ”

Early in the morning, I sat on the couch and watched the boring morning book show on TV, and this paragraph is the show's evaluation of Keigo Higashino's detective Kyoichiro Kaga. I admire Kaga's spirit, perhaps the stupidest but the most effective.

As the show ended, an idea crossed my mind, and I quickly dialed the captain's number. I didn't say anything on the phone, I just wanted to make an appointment with the captain to talk about my opinion, and the doubtful captain couldn't compete with my soft and hard bubbles, and in the end the captain could only agree.

We agreed at half past seven at a café near the police station, in fact, I don't like coffee too much, but at this time, there is no place to open except for the breakfast shop. It was still early to go to work at eight o'clock, and I came to the café at a rhythm. When I looked at my watch, I thought I would have to wait for the captain for a while. Unexpectedly, as soon as I pushed open the glass door of the coffee shop, I saw the captain sitting by the window and looking out the window. I immediately sat down across from the captain.

"What are you looking for from me?"

"There's one thing I want to see approved by you."

I actually wanted to explain the reason directly, but as I spoke, the waiter came over with the menu.

"Have a hot American." The captain said elegantly.

After the captain finished speaking, the waiter's eyes looked at me, I have never known much about coffee, I looked at the coffee on the menu with super twisted names and was speechless for a while.

"Same as this gentleman." That's all I can say.

Watching the waiter walk away, I said slowly.

"Captain, I think there are many inconsistencies in yesterday's testimony, and perhaps we will have to ask the testimony again to figure out the solution to these contradictions."

"You mean Sun Kai's testimony?"

"Yes, if his testimony is valid, then the murderer can only be him, because during that time period, Guan Hanshui and Han Tong had ironclad alibis. But the strange thing is ......"

"This testimony is of no use to him, and it can even be said that he dug his own grave." The captain looked at me firmly.

"That's right."

As soon as I finished speaking, the waiter brought me two cups of steaming coffee, and I immediately picked them up and looked at the steaming coffee, and I couldn't put my mouth to it.

"Handling cases is like drinking coffee, it's not okay to rush for quick success, it's okay to be down-to-earth, of course, if you're Sherlock Holmes, that's a different story."

I listened to the captain and slowly drank the hot American. This is my first time drinking this coffee, and most of the previous drinks were of that instant. In other words, the taste of coffee is no different from that of instant coffee, which is the taste of ordinary coffee, but when I was about to swallow it, the bitter taste instantly filled my mouth. I wanted to vomit it, but it was a bit embarrassing to do so, and I twisted my face into a ball and drank it with the unpleasant bitter taste. But even though it was in my stomach, the bitter taste still lingered in my mouth.

"Handling cases is also like drinking hot American, even if you are cautious and careful enough, there are still unexpected difficulties, and you have to learn to endure hardships. You're actually doing a good job of that. ”

I seemed to understand the captain's words, if not all of them, but I thought he was complimenting me.

"Then I will apply to ask Sun Kai's testimony again today to see if there are any new clues."

"Okay, if you need me, you can contact me immediately."

The captain took out his wallet.

"I'm here for you today."

"No, you just take a sip, or I'll do it."

The captain paid and left, and I looked at my watch and it was almost eight o'clock. I packed up and set off.

I regret that I didn't ask the captain for a police car or a private car, but if I had asked for it, he wouldn't have said anything about me. Thoughts like this swirled around in my head. Thinking of the down-to-earth story he told me and the story of Kaga that he had told me on the morning TV show, I decided to take a bus.

I contacted Cao Yang, and he told me that Sun Kai's current place is the Congxin Hotel, which is located opposite the hotel where the last death occurred. Because the place itself is not very close, and my financial situation is not very good, I can only take the bus. Speaking of taking the bus to handle the case, it can be said that it is very "down-to-earth". Around 8 a.m. was the morning rush hour, and I struggled to get on the bus. There were so many people that I couldn't see out the window, so I had to listen to the station names to decide if it was my destination.

"The labor market is coming, please prepare in advance for passengers who get off the labor market."

After I got out of the car, I found Sun Kai's residence, and I looked at my watch It was already nine o'clock. The journey took me an hour. I knocked politely on the door, and after a while, I saw a man in pajamas open the door, yes, it was Sun Kai.

"I've told the police who came yesterday everything I know." Sun Kai rubbed his sleepy eyes and showed that he was impatient.

"I still have some questions for you, I'm sorry to bother you so early."

Sun Kai seemed to see my resoluteness, and he opened the angle of the door wider and motioned for me to enter. I politely thanked me and went into the house.

"Do you need anything to drink?"

As soon as he asked, I was reminded of the bitter hot American style in the morning, and I quickly said no.

"Officer, how did you get here? I see sweat on your face. ”

"Don't mention it, I came by bus, there were too many people on the bus, and I put my hands on the top of my head the whole time, for fear that others would think I was a pervert." I quipped.

"I'm really sorry for you."

"Okay, let's get down to business, you said yesterday that you received the deceased's WeChat voice at 1:35?"

"Yes, in fact, I know that you have inquired about my family history, not my neighbor's informant, but your police will definitely investigate me. At that time, I was also puzzled that my relationship with Yuki was not as good as I said before, but he suddenly texted me. This makes me wonder. Sun Kai said calmly.

"Please forgive me for asking about you, it's our job, and if it's not related to the case, I won't tell anyone. Then let me continue to ask you, is there anything strange about you when you receive WeChat voice? ”

"No, it's just an ordinary voice, or I'll find out the chat history, you can listen to it." Saying that, Sun Kai turned around and took out his mobile phone, because he and You Qi don't talk often, so this voice was quickly found.

"Here you go, you listen."

I pressed play......

"We should have a good talk, let's go to the restaurant in the evening to make a break."

I listened intently to the voice that was only five seconds, and I listened and listened I tried to turn up the voice floor volume to the maximum and turn on the speakers.

"We should have a good talk," buzz ......, and let's go to the restaurant in the evening. Buzz ....... ”

There was a buzz in this deafening voice that could only be heard clearly when it was turned to the loudest sound, and I tried to listen carefully but it was only humming. ”

"May I ask Mr. Sun Kai, do you know what this voice is?"

I turned up the volume to Sun Kai.

"I don't know, I don't know this voice too well, and this voice is not too clear."

I took out the case notes on my body, which I learned from the captain. He always took notes all the time, not so much as himself, but directly copied all the testimony reports.

Ignoring Sun Kai's helpless eyes, I searched for the clues I wanted in my notes to see if I could explain the so-called buzz.

Don't ask me why I remember it so clearly...... Because at that time we ......

I was reading the testimony when suddenly a bold idea crossed my mind, I see, this is what is called a buzz.

"Sorry to bother you, your testimony is very helpful to me. Thank you. “

I can see that my words made Sun Kai very confused.

"Ah, that's right, you're welcome."

I bowed deeply and apologized before he left. Out of the hotel gate, I couldn't wait to call the captain.

"Captain, I know how to interpret the contradictions in the testimony."

The captain on the other end of the line didn't seem to mean to praise me.

"Then don't come back soon, I'll listen to your conclusions."

After saying that, the captain hung up the phone, and I immediately took a taxi back to the police station......
