"She transferred the money to me directly."

"Is payment made on the spot?"

"Yes, I saw her transfer the money on the spot. That kind of woman, she'll never admit to it again," the driver said through gritted teeth.

Wang Shen compared the time the driver stated with the time he saw the transfer; the times were consistent, and the amounts were correct. Wang Shen glanced at the driver, reviewing all the information he had gathered. Could the driver have intentionally caused the accident? Wang Shen had already dismissed this possibility. First, regarding the motive, although Sang and the driver had indeed had a past conflict, since Sang had already paid compensation, the matter was considered closed. Moreover, based on Wang Shen's conversation with the driver, the driver didn't seem like a vengeful person. Second, the driver had a strong attachment to his daughter. Even if he didn't understand the law, he knew the principle of "a life for a life." Without his support, it was tantamount to sending his daughter to her death. As a loving father, he wouldn't do something so foolish. Finally, and most importantly, the risk of the driver murdering Sang in this way was too great. Furthermore, getting Sang to arrive at that intersection at a fixed time required careful planning.

Wait a minute, Wang Shen seemed to have thought of something. Wang Shen's car had already driven into the police station gate. He got out of the car, waved to the police officer not far away, and whispered a few instructions. The officer then led the driver away from Wang Shen's sight.

"Go investigate another matter. Around 10 a.m. on a Wednesday two weeks ago, at the city hospital—yes, the hospital the driver who caused the accident often took his daughter to—go and retrieve the surveillance footage from that time period. See if the driver appeared in the footage. If he did, capture the entire footage where he was present. Oh, and also, help me retrieve the phone records of the deceased in the traffic accident. Find out the identities of all the callers. The last six months, I think. Yes, it's a lot of work, but there's no other way. I'll have to trouble you." Wang Shen instructed the original policeman to retrieve some clues and information, and then returned to his office.

Wang Shen wrote the names of the driver and Sang on the whiteboard. Actually, Sang's name had already appeared twice on this whiteboard. The first time was in the case accusing Zheng Wu. Now, there were three cases on the whiteboard: the first was Han Mo's locked-room mystery, and then the arrow pointed to Zheng Wu's case. Wang Shen made a dot on the whiteboard with his black water-soluble pen, wondering if Zheng Wu's case was also related to Sang's death.

Wang Shen's phone rang again. "Okay, thank you, Captain Li, thank you for your help."

The driver's license information that Wang Shen had asked Captain Li to find, as well as the details of the accident where he hit the driver's daughter, had been found. Wang Shen opened the file in his email and carefully examined Sang's driver's license information; there were no problems. Wang Shen continued scrolling down; the license plate number was... and the owner was... Zheng Wu? Wang Shen had originally wanted to find some information related to Sang from the car she was driving, but unexpectedly, the clues had returned to Zheng Wu. Wang Shen smiled wryly; Zheng Wu was really good to this hostess.

"Hello? The video has been found? So fast? Okay, send it to me." Wang Shen picked up his phone. Surprisingly, because the time interval was short and the time provided was very specific, the video of the driver and Sang at the hospital was found very quickly.

Wang Shen stared intently at the screen. A few minutes later, he received a video attachment in his email. He opened the file, and the driver who caused the accident and Sang appeared in the video. The video was less than twenty minutes long, mostly showing the driver and Sang arguing, along with the police trying to mediate. The details matched the driver's description. Wang Shen couldn't find any more valuable clues in the video. However, to ensure he hadn't missed anything important, he rewound the progress bar to the beginning and carefully replayed the video again.

Suddenly, Wang Shen clicked the left mouse button heavily. He took a screenshot of the video and then zoomed in on it several times. Behind the driver and Sang stood a person who looked familiar, as if… Because the screenshot was enlarged too much and the person was standing quite far behind the driver, the image was blurry. Wang Shen picked up his phone again.

"Yes, I'll send you a picture now. Get it fixed immediately; I need a clear image. Yes, I need it right away. I'll come to your office now. It should be fixed by then, right? Okay, thanks." Wang Shen picked up his coat and left the office.
