October 30th, 3 p.m.

"Jingle bells."

In the relatively quiet office area, the sudden ringing of the phone is particularly harsh.

"This was sent to our house this morning." Zhang Mingming's mother cried and said, "My poor daughter, she ...... She ......"

Looking at the skull that Lan Qingyan took out of the express box, Zhang Mingming's mother fainted from crying again.

"It's maddening." Duan Ayazi scolded angrily.

"There's a letter in the box." Lan Qingyan took out the envelope, and there was only one line of words: "What a beautiful skull, I am really reluctant to return you." ”

For a while, the atmosphere of the entire office solidified to the extreme.

Shangguan Yanmin got up and was about to go out.

"Huh? Shangguan Yanmin, where are you going? Qiyue stopped him.

"Find the murderer." Shangguan Yanmin said.

"Find the murderer? Do you have a clue? Qiyue asked.

"Then look for it!" Shangguan Yanmin roared: "Why else?!" Are you waiting here for the clues to come by yourself?! ”

Lan Qingyan looked at the skull in his hand and said, "If you don't want to be ridiculed behind this disgusting guy's back, go find clues." ”

After saying that, he put down the things in his hand and wanted to go outside.

"You guys go first, I'll settle Ms. Lin and go." Lan Qingyan said.

Shangguan Yanmin and Ji Yuan nodded.

Lan Qingyan drove intently, and Chi Yuan sat in the co-pilot to explain to him what they had discovered.

"The courier was sent by a woman named Lin Fei. And the courier also personally opened the box and inspected it at that time. Chi Yuan said: "At that time, there were tea leaves in the box. ”

"Was it swapped in the middle of the journey?" Lan Qingyan asked.

"It's not impossible." Chi Yuan looked at the delivery box in the back seat and said, "It's just that judging from the surface of the box...... There is no trace of opening and resealing. ”

Facing the detectives from the YN Clarifier Detective Institute who suddenly came to the door, Lin Fei was a little overwhelmed, especially the colleagues who came back and forth were watching them.

After all, everyone knows that. The YN group and the LY group are both detective offices for homicides and major cases.

Lan Qingyan sensed his embarrassment and said to Chi Yuan and Lin Fei, "Let's go to the corridor and talk about it." ”

Walking into the corridor, Lan Qingyan closed the door with her hand.

"Did you send a courier yesterday?" Lan Qingyan asked.

"Yes."

"What courier sent?" Lan Qingyan continued to ask.

"Tea leaves." Lin Fei was puzzled: "What's the matter, detective?" Any questions? ”

Lan Qingyan handed him the box: "Take a look, is it this express box?" ”

Lin Fei glanced at it and said, "It's not this. ”

"Although it looks the same, my box is also the courier box I used for online shopping before." Lin Fei said: "It's just that there is no new one." ”

"Is your delivery still in progress?" Lan Qingyan asked.

"Here it is." Lin Fei took out his mobile phone and clicked on the online shopping page and showed the two of them: "It's still in delivery." ”

Lan Qingyan took out her mobile phone and took a picture of the shipping order number.

The two of them came out of Lin Fei's office building and went to the courier company.

"The courier has been shipped to other provinces."

The staff operated quickly and transferred the real-time monitoring of the package to the two of them.

"Thank you." Lan Qingyan asked, "Are you in the personnel department?" ”

"In, the office on the right-hand side of the second floor."

Two men knocked on the door of the personnel department and showed their ID.

"I would like to ask if any of the staff members are off every six months?" Lan Qingyan asked.

The personnel department shook its head: "No." ”

"Did anyone have any of them off on July 22nd, August 4th, and August 19th?" Lan Qingyan continued to ask.

The staff of the Personnel Division quickly tapped on the keyboard and then concluded, "No." ”

Lan Qingyan was puzzled: "Isn't this person a courier delivery person?" ”

Chi Yuan said, "Will it ...... Was it before? ”
