The agents of the Security Bureau immediately rushed to Long Futao's call, and he listened very carefully to the narration of Long Futao and his wife.

"No one went to that little room the night before, did they? Right?"

"Definitely...... I wake up very easily when I'm resting, the slightest movement can wake me up, and the deadbolt of the small room is inserted from the inside. ”

"Is there a possibility that you forgot to plug it in?"

"Absolutely impossible. I woke up in the morning and pulled out the deadbolt. ”

"Is there another door or other way to enter the house?"

"Nope."

"Where's the window?"

"Yes, but it's always been closed."

"Anyway, you can take me to the room to inspect it first!"

Because the sunlight did not shine in, the light in the hut was very dim even though it was daytime, and the agent turned on the flashlight to look around.

"The bookshelves block the window."

"Yes, the room is too cramped to put it, but this bookshelf is so heavy that you can't move it if you don't have much strength."

"What's the place out of the window?"

"It's a small yard."

"Is there a room on top of this house?"

"Yes, that's where the servants live."

The detective and Long Futao worked together to remove the bookshelves, and the windows were still closed.

"There is no trace of anyone entering here, and the deadbolt is also inserted, in this case, it is impossible for others to enter!"

The detective pondered for a moment, then turned to ask Mrs. Long:

"Ma'am, do you know what happened to the necklace last night?"

This is known to many people, including servants. Because I wear that necklace every night to a party, and that's a well-known thing. However, no one else knows about the necklace hidden in this house, which is a secret between the two of us. ”

"No one else knows, right?"

"Yes, all the others...... Oh, I remember!"

"What, what do you remember?"

"By the way, I remember Anne."

"Who is Anne?"

"Anne was a friend I made when I was younger. Originally, she was born in a fairly good family, but later she had a conflict with her parents due to marriage problems, and ran away from home in a fit of anger, and then she actually got married, but it was very unfortunate that her husband died young, and now she is widowed.

"She has a young son named Little Tintin, and because I have compassion for their mother and son, I let them move here and give them a room to live in."

"Then you can be considered her benefactor!"

"Although I didn't help her much, she was grateful to me and helped us with a lot of housework, and she was a very clever person."

"Is the house of the mother and son on the second floor?"

"No, their house is at the end of the hallway,"

"So is the window of the room facing the yard?"

"Alas, yes!" Madame shook her head and sighed. After a long time, no one spoke. It seems that Madame is extremely reluctant to let her long-time friend become a suspect, so she is very concerned about this.

"Can I have a look at their room?" With that, Long Futao took the detective to the second floor. Anne was sewing clothes in that tiny room, and a little boy of about six years of age was lying beside her, reading a picture book.

There was no stove, no mattresses or curtains, and the furnishings were shabby, with some cooking utensils in one corner of the room. The detective looked at it with some confusion.

Madame was expressing pity for the plight of this poor widowed woman, but it was an exaggeration to see the scene before her. Madame's own life is so luxurious, but it is a little too stingy to treat her old friend like this. The agent thought to himself.

Seeing Long Futao and Inspector walk into the house, Anne stood up with a smile. However, she was really a little surprised by the sudden arrival of the detective, so she looked at the two of them with a puzzled look. She wasn't very old, but she was fragile and sorrowful from overwork. The Inspector immediately thought she was an honest woman, and spoke softly: "Madame's necklace is missing, so search everywhere"

"Oops!" Anne looked at them with wide eyes in fear.

"I helped my wife put on her evening dress the night before, and I also wore the necklace for her!"

"Oh, you put it around her neck...... In that case, can you provide some information about the loss of the necklace? If that's right, the burglar should have walked through the house. ”

The agent guided her verbally, and he also paid attention to Anne's facial reactions. However, she did not think that she would be the object of suspicion, so she smiled innocently and said: "This is simply impossible, I have never left this house since last night, and the windows of that cottage are always tightly closed." ”

"Well, how did you know that the burglar would enter through the window?" The agent's eyes flickered.

"Because that's where the necklace is!"

"How do you know?"

"Because Madame told me!"

She replied quite naturally, but then, her face changed dramatically, and it was only at this moment that she realized that she had become a suspect. Her face turned snow-white, and she held the child next to her in her arms and hugged her tightly.

Seeing her expression and demeanor, Long Futao hurriedly defended her: "No, we are not suspicious of you. I can vouch for you, Mr. Detective, that she is a sincere person who will not do even the slightest bad thing. ”

"That's true. From the beginning, I thought she was a very real woman, and if there was anything rude, please forgive me, I'm really sorry. The agent said.

The detective took his leave, and he reported the theft to the prosecutor.

The prosecutor spent several days searching the inside and outside of his dwellings, interrogating all the servants, carefully inspecting the deadbolts and windows of the hut, and even searching the walls and corners of the courtyard, but who knew that his efforts were in vain, and he found nothing.

No one among the servants could be a suspect. There is also no suspicious wrongness with the deadbolt. It is impossible to open the window from the outside, and naturally there is no way to close it from the outside.

"In that case, that Anne looks suspicious."

The Security Service became suspicious of her.

Subsequently, the Security Bureau deliberately conducted an in-depth inspection of Anne's daily life and movements. An investigation was made into Anne's four trips during the three years. These four outings of hers were assigned to her by her wife. Her daily work was to sew and make clothes and take care of her wife's life. However, Madame treated her very harshly. This is the common testimony of the servants.

"From this point of view, the woman is not too suspicious, I am afraid that the thief is someone else." The prosecutor came to a final conclusion.
