By this point, Xiaotao was completely convinced by my reasoning. "So you believe that the murderer’s purpose of killing Mrs. Ding is to frame Mr. Ding?"

"I can't say for certain,” I waved my hand. “The frame-up can be considered killing two birds with one stone. It not only allows the murderer to go scot-free, but it also pins the blame on someone else. We cannot yet determine which is the real motive. But we can say that the investigation of the case has just begun!”

"From the murderer's point of view, what if there’s a hiccup in one of the links of his plan? For example, what if the neighbor noticed the clock was slow?" Bingxin queried.

"The murderer would probably halt his plans for now and wait for a better opportunity. After all, who’s going to call the police to report a slow clock?!"
