She Didn't Get a Good Look

Ten years ago, Xu Zhiwei was sixteen.

She stood at the stairwell of the school building and saw a man come out of an office. There was something dark on the cuff of his right sleeve.

A police officer handed her a photograph and asked, "Is this him?"

She nodded.

Her answer sent Zhou Qiming to prison for ten years.

Ten years later, she became a legal affairs reporter.

A kraft-paper envelope with no return address arrived at the newspaper office. Inside were documents sent from the hospital by Zhou Qiming: a second testimony.

The testimony said that the person who came out of the stairwell that night wasn't Zhou Qiming. It was a man in a suit.

Xu Zhiwei began to investigate.

The deeper she dug, the harder it became to admit one thing: perhaps she hadn't seen clearly back then.

Two testimonies: one she gave herself, and one left behind by a dead man.

If the second one is true, what does that make the past ten years of her life?
