I hired the most expensive detective to shadow Lin An'an's husband and family separately.

A week later, I received the report.

This week's expenses of Lin An'an's family far exceeded their household income level.

However, Shen Bing showed no abnormalities.

Shen Bing even often cried at the company, and his boss specifically gave him three days off.

Now, he is unanimously praised by the entire company and neighbors as a "good man."

I asked the detective to send someone to inquire his neighbors about their past matters.

As for me, I went to the bank that Lin Chenglong frequently visited.

Fortunately, I am a VIP customer at this bank.

In the VIP lounge, the general manager enthusiastically made tea for me and asked how he could assist me.

I took a leisurely sip of tea and then said, "I have a friend's younger brother who recently seems to have come into a lot of unexplained income. I would feel more at ease if I could take a look at his transaction details."

The general manager immediately understood my implication: "Miss Xiang, I also have a younger brother who's quite a handful. Do you have the information of your friend's younger brother? Our bank has a duty to monitor such unexplained income."

I curled my lips into a smile, they were truly cooperative.

That same day, I deposited a large sum of money into the bank again and successfully obtained Lin Chenglong's bank transaction details for the last three months.

There had never been much money in Lin Chenglong's account, but within the week after Lin An'an's death, there were two transactions of fifty thousand each.

Both transactions came from the same account—Lin An'an's husband, Shen Bing.
