There were too many questions.

Libella was completely unable to keep up with the current situation. She could only stare blankly at the gently smiling Hathaway approaching Sherlock with a long blade. Under the moonlight, the two of them were at daggers drawn, and the victim in her arms was still wailing endlessly.

What was going on …

She furrowed her brows tightly. What was going on …

Sherlock was unperturbed by her approach. He didn't feel nervous at all. When he heard her last sentence, he even laughed out loud. He looked very happy. At least, his expression was one of genuine excitement.

"You're right. I really didn't expect you to push all the blame onto Davis. I was wrong from the beginning. I thought you were an arrogant murderer who wanted to start with me so that the reputation of the Ripper would spread. But you didn't think that way. From the beginning, you knew that the 'Ripper' would definitely be caught."

Sherlock's smile looked even scarier under the moonlight than Hathaway's gentleness.

Libella didn't know why, but she felt that neither of them were good people. Sherlock's previous indifference was gone. Facing the murderer, he became alive.

Hathaway's gentle expression was even more obvious. How many people had she looked at them like that? But how many people had died under her gentleness?

Libella didn't dare to think about it.

Yes, these two people were definitely not good people.

"You're very smart, Miss," Sherlock praised her. "But that's it. If I hadn't received Davis's letter, then I might have really thought that Davis was the murderer."

Hathaway's gentle expression cracked. "What do you mean?"

"You met Libella on the subway this morning, right?" Sherlock asked.

Libella asked in astonishment, "How did you know?"

"Because you just said outside that Davis wasn't the only one wearing red. The woman just now was also wearing red. Nina Hathaway was also wearing red."

Sherlock glanced at her. "If you didn't see Nina Hathaway, how did you know she was wearing red?

And you've been with me all day. The only time you could have met her was in the morning. In other words, Nina Hathaway appeared in East London this morning. "

"Why East London? Maybe we met on the subway?" Libella couldn't help but ask.

Sherlock looked at her. "John Watson drives her to work every morning. How did you meet her on the subway?

Not to mention the route she took to work and the route you took from East London. "

"So what?" Libella asked again.

"This proves that she didn't go home last night, or she went home and came to East London," Sherlock said.

"She said she had been kidnapped."

"Then, John would have come to me for help."

"You …"

Libella opened her mouth. In the end, she was at a loss for words. Yes, he was right.

After resolving Libella's doubts, Sherlock looked at Ms Ripper again.

He asked in return, "What else could she have done in East London at night?

Furthermore, it was between the late night of the 18th and the early morning of the 19th. It was less than 24 hours away from the 20th according to the Ripper's notice. "

Dumping the body … Libella subconsciously thought of this answer. Then, she froze and looked at the victim in her arms.

No, it was not dumping the body. Rather, the 'victim' was placed here in advance and waited for the victim to die a natural death. All she had to do was to come back on the night of the 19th to confirm if there was a need to finish off the victim.

Wait, let's extend this method.

Li Bella subconsciously looked around the quiet and dark warehouse. What if the Ripper had not planned to kill the victim in one go, but had taken it one step at a time? What if the Ripper had broken down the things she needed into countless smaller items, and then transported them here in several batches?

This would not only reduce the suspicion …

Libella looked at the cello case lying on the ground and recalled the woman on the street whom Sherlock had met earlier. What did she say?

On the night of the 16th, a woman with long brown hair carried a cello case and went deep into the alley.

I see.

Wait, she came to this world only three days ago.

On the morning of the 17th, she came to this novel. At that time, Sherlock had already sent Benben to investigate the matter. However, before Benben could investigate the matter, the other party had already set the trap.

That is to say …

Libella raised her head and looked at Sherlock.

"On the afternoon of the 16th, I received your challenge letter. On the afternoon of the 17th, you came to install a camera in 221b and lived with John, threatening me with his safety. On the morning of the 18th, Scotland Yard received your warning letter about the crime on the 20th. However, in fact, the outcome of the matter was decided on the 19th."

Sherlock spoke very quickly. Libella frowned and tried to keep up with his words.

He continued, "Do you know what the problem is?"

Hathaway's smile had disappeared, "… On the 17th, when I visited you, you already knew my identity."

"Not only that, Madam," said Sherlock. "My compliment to your cleverness lies in your vague conception of time and crime, which gives you the advantage of almost everything."

Hathaway pursed her lips and gradually tightened her grip on the blade in her hand.

"The challenge letter on the 16th foretold the crime in the second half of September.

Yes, September 20th, of course, belongs to the second half of September. "

"The warning letter on the 18th foretold the crime on the 20th.

Yes, the midnight of the 20th also belongs to the 20th. "

"Therefore, it seems that the time you left to solve the case is very tight, but in fact, it's not just tight time. The time you left is only enough for everyone to go through the procedure," Sherlock said. "From this, it can be seen that your purpose was never to compete with Scotland Yard and Sherlock Holmes. The challenge letter and the warning letter are just a cover to hide your real purpose."

Then what is your real purpose?

Libella thought of that person.

"It's Suni," she said.

Sherlock and Nina Hathaway both looked at her.

"Yes, it's Suni, child," Sherlock said, half praising her, and then said, "The letter Davis gave me is the key to everything.

Oh, by the way, speaking of this letter, you must not know that when you met Libella this morning, she came to deliver the letter to me. "

Hathaway was stunned and looked at Libella in surprise and anger, as if she was … a traitor.

Traitor?

Libella did not understand the meaning of this look.

"So, what did Davis write in the letter?" Hathaway's gloomy eyes were still hovering over her.

Sherlock raised his eyebrows and looked at her, "You told her?"

Eh?

But I have not read the letter--oh, no, I seem to have been fooled this morning--and is this retribution coming to me now??

"No, you do it." Libella lowered her head humbly, "It's your home court."

Sherlock raised his eyebrows. This reaction was interesting.

"Davis wrote in the letter —"

[Dear Mr. Sherlock Holmes,

I haven't heard from you for a long time, and I even thought you had forgotten about Whitechapel.

Now, your letter has come here again through Ben. Although it has nothing to do with that incident, I am still very happy to tell you everything.

Whitechapel, Davis, April.

I guess you mean that you want me to tell you what happened in Whitechapel in April.

East London has never been peaceful. I have been here for five years, and I should have learned what to see and what to forget. But for me, this incident, I can't forget.

On the morning of April 7th, I got up early and went out, but I saw a man in red coming out of the most dangerous red-light district in East London. There is usually no one at this time of day, and he didn't look like an East Londoner. Unfortunately, he was far away, and I couldn't see more.

But after that day, East London fell into a strange panic. That was the only time I didn't get up early and go out. After that, the bodies of a couple were found in a hidden warehouse behind the red-light district, and the murderer has not been arrested yet.

The couple's daughter was Suni. Suni's custody was pushed around for a summer, but in the end, no one adopted her. She was arranged to be placed in an orphanage in the city. But ten days ago, on September 8th, Suni came to Whitechapel.

The reason why this incident left a deep impression is that no child wants to come to Whitechapel anymore.

I hope this will be of help to your ongoing case.

Davis.]

"Davis wrote about Suni's background in the letter."

Sherlock gave a brief introduction, then said, "Suni is a very ordinary name, but too many coincidences make it extraordinary."

He said, "As early as the night of the 17th, I received a text message from John. He mentioned two people to me. One of them was Suni."

The other was Libella.

He glanced at Libella, who was staring at him with her eyes wide open.

"Suni's parents were dismembered, Suni came to Whitechapel inexplicably, and Suni was inexplicably taken away by her music teacher."

Sherlock pointed at her. "Actually, these are three questions. I'm afraid you know the answers to all three questions."

Why were Suni's parents dismembered?

Why did Suni come to the dangerous Whitechapel?

Why did Suni's music teacher take her home?

Although at first glance, it was confusing, but if you thought about these questions together …

Why was John's girlfriend interested in a detective?

Why would John live with his girlfriend on the premise of keeping his apartment?

Why was it so coincidental that John's girlfriend was Suni's music teacher?

It was like a difficult Sudoku puzzle in front of you. When you couldn't get the exact position of the numbers with the same set of conditions, perhaps another set of seemingly unrelated relationships would be the correct answer to the Sudoku puzzle.

This was one of the techniques of solving Sudoku, and also one of his techniques for solving cases.

But if all this was still not enough to make you suddenly see the light …

Then try adding another set of conditions.

The Ripper targeted female sex workers, and the dismembered bodies of Suni's parents were found near the darkest red-light district in London.

What was the common ground between the two?
