"Well, both Xiao Wang, the secretary in the company, and Aunt Yan at home have easy access to my handbag."

"Okay, we will investigate these doubts one by one. You should also think about it and see if you can provide any other clues." Su Le said.

After the interrogation of Liang Yinghong ended, Su Le contacted Liang Ronghua, and with his consent, Liang Shi was interrogated.

"Liang Shi, we need to discuss some matters with you regarding the Liang Family Courtyard."

The first release of this book: Tadu Novel App - free and ad-free, and you can interact with book friends.

"You mean Officer Su."

"Did you arrange to install the door leading to the second floor from Liang's house?"

"Yes, the situation in Liang County has become more complicated this year. Ms. Liang has been threatened and harassed many times. In order to prevent someone from breaking into Liang's house at night and harming Ms., the door was installed and the second floor was also replaced.

All windows were replaced with lockable steel screens."

"Who has the key to that door?"

"Only Aunt Yan and I have the key."

"Do the security guards of the Liang family have access to the keys?"

"I don't think so. I always carry my keys with me. I saw that Aunt Yan also hangs her keys on her body at all times."

"Are those security guards reliable?"

"Reliable. The six security guards are divided into two levels. The two most reliable people are on duty on the first floor. They are close relatives of our Liang family and can be absolutely trusted. The four security guards at the door are also absolutely reliable, but they are related to each other.

Stay away."

"After locking the door to the second floor, is it possible for others to enter the second floor?"

"No, I have carefully checked every possibility. If there is no key, there is no way for others to enter the second floor."

"Is it possible for outsiders to evade security and surveillance and enter the building?"

"This is impossible. Even if someone wants to force his way in, after he solves the security outside, there is no way to enter the room. The doors and windows on the first floor are completely closed at night. Besides, I have arranged security guards indoors on the first floor. If

Someone wants to damage the doors and windows on the first floor, and we can find out quickly."

"Okay." Su Le shook his head helplessly, thinking that when he was free that day, he would need to go to the Liang family's small courtyard to see if there were any flaws in the small building that Liang Shi said was impregnable.

Please collect it, ask for banknotes, and please read it!
