In the evening, Mr. X returns to his apartment and finds Star Swirl sitting on the couch with a book in his hand.

"What are you looking at?" He asked.

"A book that trains reasoning logic." Star Swirl didn't look up at him, her eyes falling on the page.

Mr. X let out a soft "hmm".

"Why don't you let me test you?" Star Swirl's eyes sparkle with a twist of thought, causing the man in front of her to look at her more deeply.

"Tell me about it."

Wang was arrested because he was considered a suspect in the murder. The pistol used at the time belonged to him, and only his fingerprints were on it. Star Swirl said unhurriedly,

Moreover, not only did he have sufficient motive to commit the crime, but he was also unable to provide an alibi. But Detective Y absolutely believes that Wang is not the murderer, why is this? ”

Mr. X sat down next to Star Swirl, his long eyelashes drooping, masking a faint smile, "It's because... This Detective Y is the murderer himself. ”

"Your brain is spinning fast." Star Swirl was surprised that Mr. X had given the correct answer after just a dozen seconds, and raised her eyebrows, "No, no, this is an entry-level question, I should have tested you harder." ”

At this time, Bai Xiaohan, who was ordered by Mr. X, left the izakaya and went straight to the old man's house that Han Yi visited every month.

Downstairs in the old people's community, she unexpectedly met Fu Chengyue.

"Mr. Fu, why are you here?"

was bumped into by Bai Xiaohan, Fu Chengyue's face did not show any embarrassment, he said calmly: "Officer Bai, there are some situations I just want to tell you. ”

The two walked into the alley outside the community, and Fu Chengyue lowered his voice and said, "I found that the two middle-aged people living with the old man are a little strange..."

"Kind of weird?"

"They never seem to go out together, even when they eat at the restaurant downstairs, they always take turns going there."

"Wait a minute, have you been spying on this family at night these days?"

Fu Chengyue suddenly fell silent, facing Bai Xiaohan, as if he didn't know how to explain his actions.

"Don't get me wrong, I didn't mean to blame you," Bai Xiaohan smiled, "I just don't understand why you care so much about this family." ”

"Because... Gut feeling. Fu Chengyue touched her nose and said embarrassedly, "Speaking to the police about your intuition, you must think it's ridiculous, right?" ”

Bai Xiaohan shook his head slightly: "No." ”

"As far as I know, the old man once went to a nursing home because he had no children to support, what is the relationship between these two middle-aged people and her?" Fu Chengyue asked.

"They are the nephews and nieces of the old man."

Fu Chengyue immediately realized, "However, the neighbors don't seem to know their relationship. ”

"It's also possible that it's deliberately concealed." Bai Xiaohan said.

"The old man's nephew was fired from the company a few months ago and couldn't afford the rent, so he came to her." Bai Xiaohan continued.

"It's unbelievable, I was fired a few months ago, haven't I found a job yet?" Fu Chengyue was puzzled.

Bai Xiaohan nodded: "I heard that they can also be seen coming in and out of the apartment during the day, and they don't seem to be working." ”

"But..."Fu Chengyue frowned and said, "As far as I can see, they don't seem to worry much about money, and the clothes they wear are all brand-name." ”

"In this way..."Bai Xiaohan looked at the time, "I'll visit those two now, and I'll tell you what I find." ”

Fu Chengyue stood still and suddenly said with some excitement: "Can I go with you?" Maybe... Yiyi was imprisoned at home by them. ”

Bai Xiaohan was surprised by his bold guess and felt that it was logically reasonable. Do husbands and wives take turns going out to guard someone in the house?

Han Yi disappeared on the night of the 12th, and that day was the day she regularly visited the old man. None of this seems to be as simple as a coincidence.

"But Mr. Fu, we have checked the surveillance of this community, and we have not found that your wife has been in and out of here on the 12th."

As he was talking, a fat man walked out of the apartment corridor, and Fu Chengyue whispered, "It's him." ”

Bai Xiaohan, who had seen the photo of the old man's nephew, naturally recognized this person, and waited for the fat man to walk out of a distance before quietly following.

The man was wearing a white polo shirt and a valuable watch on his wrist, as Fu Chengyue said.

The two saw the fat man turn out of the alley and walk into a Western restaurant, where Bai Xiaohan knew that the consumption was not low.

"It seems that although they do not have a job, their standard of living is indeed not low." Bai Xiaohan said.

Ten minutes later, the fat man walked out of the restaurant with two bags, and walked back slowly along the way he came.

"Go in and have a look." Bai Xiaohan stepped into the restaurant, and Fu Chengyue hurriedly followed.

"Hello, I'm the police officer in charge of this district, please cooperate with me." Bai Xiaohan showed the restaurant owner his police officer card.

The boss was obviously a little nervous, and after figuring out what they were coming to, he breathed a sigh of relief and called the waiter who had just ordered for the fat man.

"What did the middle-aged man in the white polo shirt who went out just now?" Bai Xiaohan asked.

"Two steak sets and one fried rice set." The waiter handed the list to Bai Xiaohan.

Glancing at the price, a steak set meal costs 188 yuan, while the price of fried rice is only 18 yuan.

"Fried rice is the cheapest here?" Bai Xiaohan asked.

The waiter nodded.

"Thank you for your cooperation." Bai Xiaohan and Fu Chengyue left the western restaurant.

"Three courses... There may be something strange about this. Bai Xiaohan said thoughtfully.

"Officer Bai, maybe Yiyi is really inside! You must save her! Fu Chengyue's emotions were very excited, her whole face turned red, and her hands trembled uncontrollably and grabbed Bai Xiaohan's arm.

"I see, Mr. Fu, please wait patiently for me here." Bai Xiaohan gently patted the back of Fu Chengyue's hand, turned around and walked into the corridor.

Bai Xiaohan sorted out his thoughts and walked to the door, took a deep breath and rang the doorbell.

Ten seconds later, the door opened. The door to the apartment seemed to be a little out of shape and creaked non-stop. The face of the man in the polo shirt peeked out from behind the door.

"Excuse me, I'm the police officer in charge of this area," Bai Xiaohan smiled and showed his police ID, "There are some things that need to be confirmed with you." ”

"What's the matter?" The man's fat body stood in the doorway, frowning and showing a look of suspicion.

"Someone nearby reported that they heard a lot of noise in your house."

"There's no one making noise here, can't you hear me now, officer?" The man's expression grew darker.

"But the informant said he heard a voice, can you let me in and take a look?"
