"Does the servant know where the sapphire is hidden?"

"I don't know, no one knows. Seeing that this room was turned into a mess, it is likely that the murderer did not know where the gem was. ”

"Call that servant over and ask!"

Under serious questioning, the following information was learned from the servant's answer: The victim Li Zhen did not live a luxurious life like other singers. Her private life is very scrupulous. However, since one night a month ago, after half past two, every day when she came back from the theater, a man would talk to her and leave in the early morning.

This gentleman was handsome and dashing, and it is said that he once proposed to Li Zhen. However, no one had ever seen the man's face. Whenever he passed by the porter of the apartment, he kept his hat low and the collar of his coat cocked up to cover his face. Every time before the gentleman came, Li Zhen would send the servant out, or let her go home to rest, as if she did not want to let her know what the gentleman looked like.

"In this way, this gentleman is not a good type." Wu Changhao said.

Kong Jie continued: "Yes! There must be something wrong with this guy, and we must quickly find out where he came from. ”

"Leave this matter to me!" Wu Changhao said with confidence.

"Although I am angry in my heart, Bai Lang's speculation is consistent with the case, and I have to convince people." Wu Changhao walked on the street, and couldn't help but smile bitterly in his heart.

"It seems that the place where the murderer lived was not far from the bridge and on the left bank of the river, which may well be true. However, the victim lived on Dongjiang Street. Well, the murderer must have bought the cake on the way from the bridge to Dongjiang Street. ”

So, the old detective went to all the food stores on that stretch of the road. Finally, at a food store near the station, I found that there were cakes and cardboard boxes, which were the same brand as the boxes that Shiraro had brought back.

The salesman said: "Yes, last night at a little after 23 o'clock, there was a young gentleman in a noble coat with a raised leather collar covering his face, who had come here to buy a cream chocolate praline cake." Since he wears a pair of monocular glasses, he is very impressed. ”

"Thank you."

Shiraro's reasoning is getting closer and closer to the truth. Although this kid was very arrogant, he finally found a clue and felt a lot more comforted.

Wu Changhao took the rotten newspaper that could be used as evidence and went to a newsstand to inquire about it. The old man who sold the newspaper told him, "Well, this is a scrap of newspaper about horse racing news." However, this is a direct mail from the newspaper to the customer. ”

"Thank you very much." Wu Changhao went to the Horse Racing News office, checked the list of subscribers, and wrote down the names and addresses of subscribers who lived near the bridge, especially on the left bank of the new bridge.

He returned to the Security Bureau, gave instructions to six of his men, and sent them out. In the evening, at about 19 o'clock, one of his subordinates hurried back and said, "Detective, I found a person who looks like a murderer." ”

"Well, where does he stay? What's it called?"

He lived on the second floor of an apartment on the banks of the Dongjiang River, named Jiang Jinsheng, and left the apartment at dusk the day before yesterday after taking a letter and a horse racing newspaper from the porter. At the time, he was wearing a fur coat and returned around the wee hours of the morning. That's what the porter told me. ”

"Does he always wear a pair of monocular glasses?"

"Yes, he was a stylish gentleman with a passion for horse racing. I have five or six horses, and in addition to riding them myself, I also rent them to others. ”

Wu Changhao responded nonchalantly. I thought to myself: "Bai Lang's speculation is accurate enough, I have been a security guard for so many years, and I am convinced that my observation vision will not be inferior to anyone, but I always lose to Bai Lang, this kid's reasoning and keen observation are really convincing...... This kid is not simple......" Wu Changhao couldn't help but stick out his tongue, as if he only knew that Bai Lang had such extraordinary skills now.

Wu Changhao immediately applied for an arrest warrant and went straight to Dongjiang Street with his subordinates. He ordered his men to ambush at the various exits of the apartment, and he knocked on the door, and it was a female porter who opened the door.

"Is Mr. Jiang Jinsheng at home? Wu Changhao asked.

"He's gone to dinner, and he's usually back after dinner."

"Then, I'll just wait for him for a while!"

"You can sit over there for a while!"

"No, thank you, we'll be waiting for him here."

The downstairs of the apartment is a small shop, and the room on the second floor is rented out. It was late in the day, and the shop was closed, so he hid in a corner not far away.

When the clock pointed to 9 o'clock, the female porter opened the window on the second floor where Wu Changhao was hiding and shouted to Wu Changhao: "Hey, he's back!" ”

On the main road by the river, a man was slowly approaching this way, wearing a fur coat with a collar standing up.

When he walked to the door of the apartment, Wu Changhao came out of the shadows and asked, "You are Mr. Jiang Jinsheng, right?"

"Yes, sir...... Excuse me, which one are you?" He asked in surprise.

"I'm from the Security Bureau, ...... today" At the same time, several security guards hiding in the shadows rushed up. Jiang Jinsheng saw that the situation was not right, and immediately turned around and ran, running to the door of the store that had closed. With his back to the door, he vigilantly put on a posture ready to deal with it.

The security guards hurriedly surrounded him,

"Fuck off, I have nothing to do with you security!" He shouted. At this time, I saw that his right hand was holding a thick cane, and his left hand was reaching behind his back, probably trying to open the door of the store.

Wu Changhao guessed that this kid wanted to slip through the storefront, so he shouted: "Don't make any mess of the hell, stand there obediently for me!" "While preparing to approach him. Suddenly, he remembered that Bai Lang had told him that the murderer might be a left-hander, "This kid may want to pull out a gun with his left hand, it's dangerous!" He hurriedly crouched down. At this time, only a "whoosh" was heard, and the bullet passed by.

"Uh--" Security swarmed. Jiang Jinsheng was thrown to the ground, followed by the sound of handcuffs.

After strict interrogation, Jiang Jinsheng's behavior and crime were revealed. Jiang Jinsheng is just his pseudonym, his real name is Huang Feng, and he is a habitual offender. Security found a bundle of rope like a bundle of newspaper in his quarters. At the same time, a dagger was found that closely matched the victim's wound.

This kid must have been a murderer, but he could prove that he was not at the scene at the time. He said that on the night of the crime, he was in the theater, and he was in the theater from beginning to end, and he had the theater ticket and the outline of the performance that night in his pocket, and the theater ticket was stamped with a certifiable date and performance. However, the saleswoman at the grocery store pointed out that he was the man who bought the cream cake that night. In addition, the female doorman in the apartment also pointed out that it was this gentleman who came to Li Zhen every night to find the singer.
