Keep an eye on him

Qin Yan and Yun Jian immediately left the latter's house to investigate the case.

In the first suspect's house.

A servant served two glasses of water to Qin Yan and Yun Jian. The two looked around the house of the suspect carefully.

"What the hell is going on? Why did you pierce her hand so hard? I give you money to take care of my wife and not to torture her. Do it properly," A man roared at the nurse attending his sick wife.

"Sorry Sir," the nurse apologized.

The man stormed out of the room and saw Qin Yan and Yun Jian.

"Yes ladies, what's the matter?" he asked them.

Yun Jian got up from the couch and introduced herself, "Hello, I am Senior officer Yun Jian from crime branch."

"Oh, please sit," the man offered seats to the duo.

"It's a routine inquiry..."

"Do you mind if I smoke?" the man interrupted Yun Jian.

"No.."

"Thanks. So how can I help you?" The man asked the duo.
