Katie lived in Rome until she was 13.

Half of the books she usually reads are in original Italian.

In the early hours of last winter, the window knocker heard strange knocking sounds from the third floor of Freeman's house several times.

'1,9,empty,2,1,2. '

这组敲窗人听到的敲击数正确排序该是,1,9,2与1,2与空,1与5。

Empty represents 0, which constitutes the order of 1, 9,21,20, 15, [-], [-].

分别对应到26个字母的排列,1—A,9—I,21—U,20—T,15—O。

It forms an Italian word: "AIUTO (help)"

Kelsey and Sherlock thought of this, and immediately stood up from the soft chairs.

Kelsey asked the footman, "When was the last time the knocker heard something strange? Is the knocking the same as usual?"

The servant Wiggins asked the window knocker carefully, and he said with certainty, "Today, March 3, the last time the window knocker heard the knocking sound was in the early morning of March 7. But it is different from before. It stopped after only five knocks."

At noon on March 3, Katie disappeared.

In the early morning of March 3, the knocking sound was not as rhythmic as before.

In the past two days, no knocking sound was heard.

Sherlock sensed that the situation was not good, and solemnly told the servant, "Wiggins, please keep an eye on Katie's house. Especially if there is a carriage coming in and out, try to find out where the carriage is going."

Wiggins solemnly promised to complete the task, and he left first.

Kitty's family did not keep a carriage.

Freeman is the only one in the family who needs to go out to work, and his bar is very close to his home, usually within walking distance.

Now why beware of carriages coming in and out?

The answer couldn't be more obvious, Freeman might move Katie from custody.

The strange knocking noises started last winter.

At that time, Katie's rash broke out, and it was rumored that she had been hit by the blow and got mad.

Locking up mad patients seems like a matter of course.

It was a logical move for Katie to move her out of her second-floor room and into a third-floor or cramped attic through her messing around.

Therefore, the sound heard by the person who knocked on the window came from the third floor of Freeman's house.

Katie was most likely restrained, such as shackled, or even more likely gagged.

She wants to send out a message for help, so she can only make noise during quiet hours, and it is most suitable for her to sleep until the early hours of the day.

The work route of the window knockers is basically fixed.

Because of the nature of their work, they are also particularly sensitive to knocking sounds.

Katie makes knocking noises in the wee hours.

Perhaps worried that the distress signal would be deciphered by Freeman, she chose to piece together the Italian text.

"Mrs. Freeman is British. Although she has been married to Rome for many years, her Italian is very poor."

When Sherlock took Katie's library, he asked Mrs. Freeman if she knew how her daughter was reading. "Mrs. Freeman said that she didn't have much communication with Katie. She could hardly understand the contents of the Italian books that Katie said."

It's not just a mother's inability to guide her daughter.

Kelsey wonders why Mrs. Freeman married Katie's biological father Karen in the first place.

"I have lived in Rome for more than ten years, but I have not mastered basic Italian. Karen and Katie's mother, can this couple have a good relationship? Did Mrs. Freeman really take care of her first marriage?"

"Maybe it's because of the face?"

Sherlock has seen a photo of her biological father in Katie's room, "The late Mr. Karen is very elegant, and he can beat the ordinary Freeman by dozens of streets. And Karen is a lawyer, with a considerable income."

The money is in place and the face is good.

In this era, there are not many marriageable men who satisfy these two points at the same time, and how many people would require deeper communication.

Kelsey couldn't help but think of the Bennet family.

Compared with the situation in Katie's family, Mrs. Bennet and old Bennet don't have much in common, but she can be called a mother who loves children very much.

One day, one day, Mrs. Freeman was cruel to her own daughter.

The two detectives put on their coats while talking, and went out to find someone to carry out a raid.

Because of the sudden new clues, the original plan that was planned and then acted was disrupted.

Now we can't wait for Watson to go to Italy to determine whether Katie will inherit the inheritance. We must first forcibly raid the Freeman's house.

The last time the knocker heard something strange was in the early morning of the day after Katie disappeared.

The unrestrained rhythm of that knocking sound probably indicated that Katie was in a very poor physical condition and could not fully send out the signal for help.

Now I can only pray that it is not the most regrettable ending, and that Katie can hold on and not be silenced.

Sherlock went straight to Scotland Yard.

The Freemans' house must be thoroughly searched tonight, and it is a matter for Lestrade to be involved.If Katie cannot be found, Freeman and Doreen must be arrested and put in prison first.

"My God! Mr. Holmes, what are you doing here?"

Lestrade was about to leave work when he was blocked at the door of the office.As soon as he saw Sherlock, he thought something was wrong, why no kind person informed him that the devil had returned to London.

Sure enough, without any polite greetings, Lestrade was 'requested' to help solve the case immediately.

Sherlock succinctly talked about the two disappearances, "Inspector, I am now formally reporting the case to Scotland Yard. Please organize your staff immediately and go to Katie and Aggie's house separately. Apprehend the suspects involved in the joint crime."

Lestrade: ...

The ellipsis is not enough to express the mood, but I really don't know what else to say.

It turned out that the devil just returned to London yesterday morning, so how could he find something for him this evening?

"Very well, Mr. Holmes, you always want me to work overtime."

Lestrade did not agree to arrest the person directly, "According to the existing evidence, everything is still your and Mr. Bennet's speculation, and there is no hard evidence. Let me arrest people, I will risk..."

It's about taking a risk.

Before the sentence could be finished, Kelsey and Billy Lachel arrived one step behind.

"Fortunately, the evidence has been preserved. Today, Mr. Rachel turned the house upside down and finally found Katie's typewritten letter."

Kelsey patted a crumpled piece of paper and another letter on the table, "The front is Katie's list, typed with a typewriter. The back is Heller's love letter to Aggie, also written Typed on a typewriter. Inspector, please compare."

Lestrade didn't look at the list and the love letter first, but looked directly at Sherlock, only to see the corner of the mouth of the great detective Sherlock Holmes slightly hooked. "Since the time is short, two detectives, please make it clear."

"You have said so, and I will not waste any time."

Sherlock spread out the list and the love letter, "For the love letter sent by Heller, due to reasons such as the time of sending the letter and the storage status, no valid fingerprints could be extracted from it."

Otherwise, it can be directly compared with Freeman's fingerprints.

"If this method doesn't work, then try another method."

Sherlock signaled Lestrade to pay attention to the font and ink on the two sheets of paper, "Typewriters are not new, but people rarely notice one thing - typewriters on the market today, even if they are the same model, each has subtle differences .”

After last year's "Lucky One" threatening letter incident, two detectives studied the condition of the typewriter letters in more detail, identifying subtle differences between each typewriter.

At the moment, Lestrade carefully compared the two letters, and confirmed that the handwriting and ink dots were exactly the same.

"Wow! I see what you mean. Katie used the typewriter at home to make the list, and Freeman used the same typewriter to write the love letter. This is the best evidence that Freeman is pretending to be Heller. Okay, I Can work overtime."

Lestrade pointed out the window, "According to the existing clues, I can arrest Freeman and the others for two days. But the sun has already set, where can I get a search warrant now?"

Kelsey smiled, and looked at Lestrade with eyes she hadn't seen for a long time, "I haven't seen you for a few years, Inspector, you have changed. For a while, I don't know whether I should praise you for being more polite and polite, or worry about your rigid thinking. the trend of."

Lestrade:!

The exclamation point was not enough to express his mood, but he hesitated and couldn't refute immediately.

God knows if the devil is more capable of hiding a knife in his smile when he returns from the United States?It hurts to be stabbed once, do you want to take the initiative to try a second time?

Kelsey told Lestrade straight to the point: "Wait a minute, you and Mr. Holmes catch Freeman and his two accomplices in his family. At this time, Mr. Lachel, as his fiancé, is very concerned about Katie's situation." , took advantage of the unpreparedness of the police detectives and rushed upstairs to find someone."

Billy clenched his fist and nodded, "Yes, I'm ready. I know the layout of Freeman's house better, so I rushed directly to the third floor. The bedroom opposite the Freeman couple is an unused storage room, most likely to hold Katie , or in the attic."

Kelsey continued, "I quickly chased after him to tell Mr. Rachel not to be impulsive, but he didn't listen. During the persuasion, we accidentally knocked open the door on the third floor or the attic. What we should find is It can be sent. In this way, do you think there are still problems in the procedure?"

Lestrade: Accidentally crashing into a crime scene is something most people dare not say.Such an arrangement gives more consideration to avoiding violations and crimes.

"As expected of you."

Lestrade accepted the arrangement without saying anything, and then called Carter and other detectives to arrange arrests separately.

Kelsey accepted the compliment without changing his face.

Lestrade has never experienced such creative ideas as detectives robbing prisons and detectives suspended animation, otherwise he would have come up with excuses to search the room at his fingertips.

Ado.

Go straight to Freeman's house.

Seven o'clock at night.

The Baker Street Squad, who was watching nearby, determined that there was no movement at Freeman's house.

'knock!knock!knock! '

Three heavy knocks knocked on the door of Freeman's house.

"What are you doing?"

The maid, Nita, opened the door. When she first saw the combination of detectives and Scotland Yard detectives, her heart skipped a beat.

What?

Of course it is arresting and saving people!

In the living room, gas lamps light the dining table.

Freeman and his wife are enjoying dinner, wine, meat, vegetables, soup, etc.The two ate with peace of mind, not at all like losing their daughter and losing their appetite.

This meeting was blocked right away, how could such a brutal Freeman be willing to obediently catch him without a fight, he actually pulled out a harpoon from behind the curtain.

Seeing the melee will start.

Compared to the scruples of the police officers, Sherlock rushed forward and hit Freeman with a few punches in the face.

On the other end, just as the script arranges.

Billy and Kelsey rushed up to the third floor.

Katie was not found on the third floor, but the attic door was locked with an iron chain from the outside.

'Click! '

Kelsey opened the brass lock in twos and twos and pushed the door open. The room was pitch black, and a foul smell wafted out.

Billy entered with a gas lamp. There was only a single bed in the cramped attic room.I saw Katie's limbs were tied to the bed board, her hair was covered with dirt, her eyes were closed tightly, and a rag was stuffed around her mouth.

"Katy? Katie! Wake up!"

Billy didn't get a response, so he checked Katie's breath with trembling hands, and immediately turned to Kelsey and said, "Fortunately, she's still angry."

Right now, Kelsey has only one thought: I hope dear Mr. Holmes punches Freeman more.For that kind of scum, it is a gentleman's behavior to beat him hard.

The author has something to say:

Note: The subtle difference of the typewriter comes from the original work of Lao Fu.
