Shen Xin and Ding Yuwei drove toward Pingyu.
Using traffic surveillance footage, they had locked onto the minivan.
It was a ride-sharing vehicle.
They used the license plate to pull up the owner's information.
A Pingyu local.
They had already contacted him and arranged to meet at the hotel where Jiang Qi was dropped off.
As for Wang Xin'ning, Chen Chao had taken her in to cooperate with the investigation.
They still needed a detailed statement from her about the specifics of Jiang Qi's departure.
Ding Yuwei sat in the passenger seat, a notebook spread open on her lap, scribbling and sketching.
She had taken a photo of the puzzle from the letter Jiang Qi left behind and was now copying it down.
"Why are you studying that?"
Shen Xin muttered while they waited at a red light.
The puzzle was a 10x10 grid of letters, 100 letters in total, all jumbled randomly with no discernible pattern.
Ding Yuwei had been scribbling at it for a while. "It might be a clue," she said.
