Throw a Stone in the River to Find out the Depth

"What's the matter, honey?" Miao Ying asked after she noticed Zhao Yu's frustration. "Do you think that Han Kuan's case is not quite solved yet? I never would have expected that our super detective, who has solved so many difficult cases, could be stuck on such a simple case now! You know that it has to be either Han Kuan or his wife."

Cui Lizhu, who had been silent for a long time, nodded and said, "Yeah! It's either Han Kuan or Zhang Jingru! Since it happened in a locked room, it must be one of them! In my opinion, now that we have the recording, it's solid proof! What else are you worried about? Let's just close the two cases together, right now!"

Cui Lizhu then pouted her lips and added, "This could be a great help to reduce my sentence..."

"Little girl, don't talk nonsense now!" Zhao Yu shook his head and rolled his eyes at her before he said, "What we want is to find out the whole truth! I can't ruin my super detective reputation over this case!"
