The detective had an idea and asked:

"Madam, Fu Yude is already sixteen years old, in terms of age, will you have such a big child?"

"Yes, he is not my biological child, he was born to Fu Yucheng's ex-wife."

"Oh?"

The detective and Lang Xiaobai glanced at each other.

Since he is not his own flesh and blood, he may not really love him, not to mention that she and Fu Yucheng don't seem to really love each other, in order to try to get a huge inheritance, so as to kill her husband and children who he doesn't like......

This strengthened the detective's suspicion of Xiao Xiurong.

Because the inspector had doubts about Xiao Xiurong, his suspicions about Lang Xiaobai disappeared. "Madame, have you ever seen this gem?"

The detective suddenly asked Xiao Xiurong. Xiao Xiurong took the gem, put it in the palm of her hand and looked at it carefully for a while, shook her head and said:

"I haven't seen it, I also have a necklace with Turkish gemstones. However, the gem on it was bigger than this one. ”

"Then show me your necklace."

Xiao Xiurong did not hesitate to take out the jewelry box from the bedroom. In addition to the Turkish gemstone necklace, there are many necklaces, rings, earrings and other jewelry, all of which are sparkling jeweled diamonds.

"Such a big Turkish gem!"

After the inspector had looked at all the jewels, he opened the lid underneath and saw two keys inside.

"This is the little door in the yard and the key to the entrance. Sometimes I come back late from the ball, and it is inconvenient to ask the maid to open the door, so I can come in with the key. ”

Xiao Xiurong said calmly about the purpose of the key.

"Do you often go to proms?"

"Yes, after watching the opera last night, I went to Lady Delu's ball."

"Do you always ride in your own car?"

"After the opera house ended, I took a taxi to Madame Delu's house."

"What time did you leave the theater?"

"Around eleven thirty."

"What time is it at Lady Delu's estate?"

"Hmm...... It's ......"

At this time, I realized that the detective had doubts about himself.

"Yes...... Is that...... I didn't look at the watch...... Probably less than two o'clock. ”

Such an answer makes one more skeptical.

Fu Yucheng was killed at 12:30, and the lady who left the theater at 11:30, why did she arrive at Mrs. Dailu's manor at nearly 2 o'clock? These two places are not far away, and it won't take that long! It is likely that during this time, Xiao Xiurong sneaked home, opened the door with a key, and poisoned her husband and children.

The detective made such an inference about Xiao Xiurong's actions.

"Madam, you take a taxi all the way to Lady Dailu's manor, shouldn't it be two o'clock?" The detective asked sharply, apparently with a handle.

Xiao Xiurong's face changed abruptly......

"I ...... When I was at the opera house, I was a little dizzy and wanted to get some fresh air, so I told the driver to drive slowly to the Arc de Triomphe, and then slowly drove back again. So it took a little longer. ”

The detective immediately questioned Mrs. Dailu by phone and confirmed that Xiao Xiurong's time was correct, and she sat there for more than ten minutes before leaving.

But where did she go between eleven thirty and two o'clock?" Going for a ride" is unreliable.

The detective and the security director both thought that Xiao Xiurong was a murderer, but Lang Xiaobai didn't think so. He pulled the Inspector aside and whispered to the Inspector:

"Although Xiao Xiurong is suspicious, it cannot be asserted that she is the real murderer."

"Why? But she had evidence of being 'at the scene', and besides, after the death of her husband and children, she became the heir to 20 million gold dollars......"

"However, as far as I know from the Shimbashi Cafe, the person who stole Agent Wang Lin's report and envelope was holding a rosewood cane with a silver-white bird's head. Therefore, the murderer should be someone else. ”

"Makes sense. That person is the murderer, and Xiao Xiurong must be an accomplice. In any case, she should be detained first. The Chief of Security said.

Inspector Wu said: "How can you arrest her without sufficient evidence?"

"Nope! The evidence is enough. She had two keys that allowed her to enter and exit in the middle of the night. And, from 11:30 to 2:00 a.m., the period between 11:30 and 2 p.m., the period of time when the movement is not clear, isn't that conclusive evidence?" said the Chief of Security.

"But...... Detective, you have to be clear, the murderer who came last night is a man!" Lang Xiaobai said.

"What? How do you know? Is there any evidence?"

"There are man's shoe prints in the yard, and I found a stronger ......"

"What's more powerful?"

"It's this ......"

Lang Xiaobai took out the apple he picked up and handed it to the detective.

"Huh? The tooth marks on this are exactly the same as the chocolate candy tooth marks that Wang Lin brought back. The detective's face changed.

Lang Xiaobai said in a deep voice:

"This is what I picked up in the grass in the yard. The murderer must have brought it from the study, and he threw it away after taking a bite.

"So, the tooth marks must be Madame's?"

Lang Xiaobai smiled and said, "It's so boring! How can such a beautiful woman have canine teeth. Most likely, it was a man's tooth mark with a cane. ”

"Maybe! Anyway, I'll have to get my lady's teeth checked first. ”

"Forget it! Detective, don't waste your time. ”

Although Lang Xiaobai did not agree with the inspector to do this, the inspector still took an apple from the small fruit bowl, came to Xiao Xiurong and said:

"I'm sorry, please take a bite."

"Huh? Bite the apple...... Why?"

"Because we found the killer's tooth marks, we want to see if your tooth marks are the same as the murderer's. If not, so much the better, and you don't have to be suspicious. ”

"Alas! What's wrong with me? Why doubt me?"

With tears in her eyes, the lady said angrily, "I don't bite ......."

"You don't bite? The suspicion of you is even greater. ”

"So, you have to bite?"

Xiao Xiurong's expression was very depressed, and she was about to cry.

"Madam, please take a bite! As long as you bite, you can return your innocence. ”

Xiao Xiurong clenched her teeth, closed her eyes tightly, and refused to obey her fate.

"If you really don't bite, you can't prove that you're not suspicious." The detective urged her repeatedly.

"If you have to bite......"

Xiao Xiurong looked at the inspector very angrily.

The detective gently handed the apple to Xiao Xiurong.

"If that's the case, then ......"

She trembled all over, looked at the apple, then puffed up her manly spirit, took the apple, took a big bite, covered her mouth with a snow-white handkerchief, closed her eyes again with a very distressed expression, and handed the apple to the inspector.

The inspector took the apple, came to Lang Xiaobai's side and said:

"Now compare the apples you have picked up!"

The tooth marks on the two apples are exactly the same. Lang Xiaobai observed it carefully, and his face changed.

"And voila! You still say that Madame is not a murderer?"

The detective showed a smug look and walked up to Xiao Xiurong, "Madam, please come with us to the Security Bureau." ”

"Huh? What do you say?"

"Because you are suspected of killing your husband and children!"

Xiao Xiurong screamed and fainted.

"Madame is the murderer? So a beautiful woman is a killer? No, it won't be her......... But the tooth marks ...... It's weird, it's hard to understand...... There must be a conspiracy in this, it must be an unusual homicide...... I don't believe Madame is the real murderer. ”

Lang Xiaobai thought while accompanying Xiao Xiurong into the police car and drove towards the Security Bureau.

The next day, the Security Bureau formally arrested Xiao Xiurong. After all, there is ample evidence to prove that she is the murderer of the case.

One of the pieces of evidence is that the apples picked up in the yard are the same as the apples that Xiao Xiurong has bitten, and the tooth marks on them are exactly the same as the chocolate candies left by Wang Lin. The second piece of evidence is that, according to the taxi driver, at about 11:30 p.m. on the night of the crime, a beautiful lady in her thirties was pulled at the entrance of the opera house and drove to Wanfu Street. Xiao Xiurong got out of the car and left, the time was 11:45. Wanfu Street is very close to Fu Yucheng's family, and no matter how slow a woman walks, it won't take five minutes. Therefore, she may have used this time to kill her husband and children, and then took a taxi to Mrs. Dailu's estate, besides, the taxi driver specifically pointed out that it was indeed Xiao Xiurong who pulled that night.

With this evidence, the detective immediately ordered Xiao Xiurong to be sent to prison and imprisoned. The news did not go away, and various newspapers and periodicals carried the titles of "Dogtooth Killer Demon King" or "Femme Fatale" and so on, and hyped up the whole Dongzhou City, which caused an uproar.

Although people think so, Lang Xiaobai doesn't think so, sitting alone in the luxurious study, drinking coffee and thinking: Such a beautiful woman is so suspicious, it is too sympathetic...... There must be an untold conspiracy in this......
