Looking at everyone's shocked looks, Xia Xibei smiled, a little embarrassed.
"Well, I'm kidding. Actually, I noticed that something was wrong just now."
"How?" The police officers immediately became serious.
This was a very important clue.
"I was just waiting for her downstairs," she pointed to Nora, "Then, I saw him walk past me."
Everyone frowned, but didn't say anything.
So he was just walking past. What was wrong with that?
"If it was just once, forget it, but I noticed that he walked twice." Xia Xibei had a serious look on her face. "I also noticed that he looked a little bit wrong."
"What's wrong?"
She looked innocent and serious, "He was very nervous and a little bit crazy."
