Guilty

It was two in the afternoon at the Bai Ling Police Station, when Zhao Yu brought Cui Lizhu to the captain of the police detective's room. The captain's surname was Sun, and he was fifty-nine years old. Nineteen years ago, he was the one that had arrested Cui Fangyu.

As Zhao Yu and Cui Lizhu entered his office, Captain Sun immediately poured them a cup of tea and said, "Ah, you are just in time! If you were to have visited even a week later, I would already be retired! I heard about your working on a case that I was involved with twenty years ago!"

Then, Captain Sun passed a cigarette to Zhao Yu, but Zhao Yu refused it politely.
