Chapter 115 Bai Ci•Holmes•Lin_4

"Are you sure there's an issue with someone living in Building 9?"

Xia Hongyao was excited. If she could solve the mad dog incident today, her position in the bureau would also be recognized.

"Not sure, let's check it out!"

Lin Baici entered Building 9.

With three apartments per floor, Lin Baici did not know which one it was, so he had to ask each in turn.

Thump, thump!

Lin Baici knocked on the door with a bent finger.

"Who is it?"

It was a woman's voice.

"Delivery!"

Lin Baici replied.

"I didn't order anything."

The woman answered.

Lin Baici knocked from door to door.

If a woman answered, he could almost rule it out. If a man answered, Lin Baici would claim he was from the gas company and needed to urgently check the gas valve.

As soon as the door opened and Lin Baici saw that the person was not Du Shan, he would immediately ask, "Is this apartment number so-and-so?"

Of course, the answer was 'no'.

Then Lin Baici would apologize and move on to the next one.
