Three months before he was killed, Fu Yucheng wrote several letters to a friend of his named Lanzano. He didn't know that Lanzano had died inexplicably years ago. As a result, all the letters sent out were returned. The Buddha wiped off the addresses and names of the recipients of these letters, then put them in a timer machine that he had made, and finally placed the machine on top of the multicolored lanterns. He set aside the first letter on the fifteenth day after his death, and the rest of the letters, every ten days, dropped one after another.

In addition, Fu Yucheng carefully reconnoitred Luo Cai's whereabouts, and found that every time he went to the nearby hill on Wednesday night, facing his own house, he also found that Xiao Xiurong also opened the window at the same time, looking at Luo Cai from a distance.

"There are a few other points that I hope you will pay special attention to, first, Fu Yucheng was killed on Wednesday. Second, that night, Xiao Xiurong did not take the initiative to ask to go to the opera and attend the ball, but went out because of her husband's trick. ”

"I see." Everyone couldn't help but nod.

Also, on the day of the crime, Fu Yucheng imitated Luo Cai's handwriting and sent a letter back to Xiao Xiurong, asking her to meet him at the Arc de Triomphe at about eleven o'clock that night. Therefore, after Xiao Xiurong left the opera house, she took a taxi to the Arc de Triomphe to make an appointment, of course, Rhodes would not arrive. By the time she left the Arc de Triomphe in disappointment and returned to Madame Delu's house, it was almost two o'clock. Therefore, when the detective asked her to tell her whereabouts during this time, she was unwilling to tell the truth, so she was unable to provide an alibi, and finally was charged with murdering her husband.

Although Fu Yucheng planned very thoughtfully, he didn't expect to meet Agent Wang Lin. Detective Wang Lin was ordered to investigate the heir to the huge inheritance, and finally found out that Fu Yucheng was the legitimate heir, and arrived at Fu Yucheng's home, which was in this house.

"No one knows what they were talking about. In short, it is undeniable that Agent Wang Lin used ingenious methods to get the chocolate candy printed with canine tooth marks and discovered Fu Yucheng's conspiracy. Because of Fu Yucheng's stubborn revenge, Agent Wang Lin felt very frightened. At the same time, he also found out that Fu Yucheng, father and son, would be killed that night. ”

"Why would he know?" The detective interjected.

"Then I don't know. We can't ask about the dead, but I speculate that Wang Lin may have used clever methods to get Fu Yucheng to be fooled and tell his own conspiracy.

When Wang Lin heard about his vicious plot, he must have trembled with fright. When he was about to leave, he didn't expect to be stabbed with a poisonous needle by Fu Yucheng. I didn't feel any pain at the time, so I went straight to the Shimbashi Cafe to write a report. Because the poison needle is slowly absorbed, there are no symptoms.

After Wang Lin left, Fu Yucheng quickly pretended to be Luo Cai and also came to the Xinqiao Cafe. Because, Fu Yucheng once saw Rod in the park, wearing tortoiseshell-framed glasses and holding a rosewood cane. Therefore, he dressed up very similarly.

Fu Yucheng, who was dressed up, deliberately asked the shoe-shining child for directions after changing Agent Wang Lin's report at the Xinqiao Cafe. The security guards fell into his trap and followed the clues provided by the shoeshine child to find and arrest Rod Cai. ”

"Ahh What a sinister and treacherous fellow!" For Fu Yucheng's treachery, Deputy Inspector Lu Pei was very surprised.

"Yes. He's so intrigue, he's like a devil!"

After reversing the report at the Shimbashi café, he was still not at ease, so he went to the Security Bureau, pretended that he was going to be murdered, cried and screamed, and asked for protection. Because he acted so similarly, the detective and I thought it was true, so we fell for him.

Later, in his house, he deliberately took out the gray booklet in the safe for us to see, pretending that the killer was about to come to his house, etc...... It was all his own trick.

"After Li Yunshan and I walked into another room, he pretended to sleep for a while, and then he started another higher scheme."

"What kind of ploy?"

"He took the Turkish gems that had fallen from my ring, put them in the drawer of the safe, and then hid the gray booklet. But he didn't know that the gem had fallen from my ring, and he thought that his wife, Xiao Xiurong, had accidentally fallen from the living room.

"He thinks that as long as he puts Xiao Xiurong's gems in the safe, he can blame her."

"I see!" Except for the Inspector who said a word, everyone else was silent.

"The more I listened, the more confused I became. Lang Xiaobai, no, Mr. Bai Lang, are you saying that Fu Yucheng hates his wife and Luo Cai for falling in love, and tries to make them convicted of murder together?" Lu Pei asked.

"Yes."

However, since Fu Yucheng knew that he would be murdered that night, why didn't he think of a way to resist or escape? You open your mouth and say that he wants to blame Madame and Rod Cai, but. . . Deliberately being killed for the sake of revenge does not seem to make sense. Lu Pei said.

"Nope! Fu Yucheng was not murdered. ”

"What? Haven't you already been murdered?" Everyone was confused.

"Yes, because he wasn't killed, there was no murder."

"That's!" Lu Pei slapped the table vigorously and shouted

"He wasn't killed, but he was dead. In other words, he committed suicide. ”

"Huh?"

"He injected himself with poison, and at the same time, his son was taken away by him." Lang Xiaobai said confidently.

For Lang Xiaobai's reasoning and judgment beyond ordinary common sense, the detective and the others felt very confused, and everyone was guessing that Lang Xiaobai might be a little abnormal, and they all looked at his face.

No one dared to speak. The silence in the room made it feel like a graveyard, and it was very cold.

At this time, the fire had been extinguished, the air conditioner was blowing, and the only candlelight was blown on and off, which made everyone present feel creepy.

Lang Xiaobai looked at everyone with a comfortable expression, and then broke the silence, "Detective, do you remember when Fu Yucheng ran to the Security Bureau to ask for protection?" On that day his face was very pale, as if he had just come out of the grave, and when I looked at it, I thought he was suffering from a very serious illness. In the evening, Li Yunshan and I spent the night at his house, and when we saw his son Fu Yude's bloodless face when he slept, I felt that the child was not as healthy as an ordinary child at all. Later, I found out that the illness of their father and son was closely related to this bizarre case. ”

Lang Xiaobai took out a letter from his pocket and said, "This letter was just found from the secret drawer of the safe, and it is Fu Yucheng's handwritten letter. ”

Lang Xiaobai pulled out the letter paper and continued: "This was written by Fu Yucheng before committing suicide, the time was 11 o'clock in the evening of March 31, and his own name was signed at the end of the letter. In this letter, he clearly states the motives and means of revenge. ”

The letter reads as follows:

"Before I die, leave this letter - this is my last confession, every sentence in it is a true fact, not at all false. What I planned to do, it took a long time, and finally I had initial success. That hateful pair of men and women, I finally have a chance to take revenge on them.

Fu Yude slept soundly, I injected poison injections on him, and he will always fall asleep sweetly. After writing this confession, I will also inject poison injections on myself, so that I can go to the happy kingdom of heaven with Fu Yude. Even if we were to live, we would not live for a year at most. Therefore, I am very happy that we were able to leave this painful and sad world sooner.

I had terrible cancer, and Fu Yude also had a very serious lung disease. Four months ago, I took him specifically to London to have a well-known internist check it out. As a result, the doctor said that both father and son were suffering from incurable diseases and would live for another year at most.

At that time, I swore revenge! Therefore, I tried my best to get the dog man and woman to be guillotined after the death of our father and son. They are my wife, Xiao Xiurong and Luo Cai.

I can't forgive both of them for being in love. I struggled to come up with a novel solution—

I first killed Fu Yude with poison, and then committed suicide with poison injections. If this is the case, the Security Bureau will definitely think that Xiao Xiurong and Luo Cai are the murderers, and then arrest them.

However, this plan was known to Agent Wang Lin. In order to extinguish the mouth, he must be killed. In addition, in order to divert the target of the Security Bureau, I disguised myself as Luo Cai, followed Wang Lin to the Xinqiao Cafe, and stole his report. Just now, Xiao Xiurong's Turkish gems have been put into the safe by me. In this way, the Security Bureau will definitely think that they are both murderers.

The agents of the Dongzhou Security Bureau, all of whom are stupid and confused, will definitely proudly announce the cracking of the case. If that were the case, I would be able to laugh at those stupid fools underground.

My plan is tight! A few months earlier, I had written to the deceased Lanzano, and of course, they had returned intact. I put the letters in a special clock and put them on top of the multicolored lanterns. I dialed the mechanism of the clock, and let the first letter fall fifteen days later; The second, third, and fourth letters fell every ten days. After the fifth letter fell, the time bomb hidden under the table would blow up the machines on the multicolored lanterns, the gray manuals, the poisons, the syringes, etc., and there would be no physical evidence left.

In this way, my hateful wife and Rhodes will surely be guillotined for murder. Actually, the real killer is myself! When I die, my soul will know that it will laugh at both of them. At the same time, laugh at the Dongzhou security guards and judges who fell for my tricks.

I'm thinking at the moment that the look on their faces after reading this confession must be very funny, and their faces will definitely be like turkeys, red for a while, green for a while.

I will laugh at them heartily under the nine springs. No! Now, I'm going to laugh out loud first, hahahaha......"

After reading the letter, everyone seemed to hear the laughter of the murderous devil Fu Yucheng from under the Yellow Spring, and they couldn't help but feel creepy.

"Fu Yucheng hated his wife and Luo Cai too much, so he went crazy." The inspector said with a sigh.

"Yes. Because he was too jealous, he came up with this plan for revenge. Lang Xiaobai also sighed.

In this way, Xiao Xiurong and Luo Cai are innocent. We'll need to hurry up and get the trial magistrate to release them. ”

"Bai Lang, no! Mr. Lang Xiaobai, please come with me. Mrs. Xiao Xiurong will definitely be very grateful to you. Lu Pei looked at Lang Xiaobai and smiled.
