The case was at a stalemate. All they had to do now was wait for Zheng Qiu's autopsy.
If the place where miss Feng Si was found was not in the Feng residence, then it was still fine. They could go to the scene to take a look. However, it was so far away. Going to the Feng residence to check back and forth would probably take midnight.
Back and forth?
Feng fourth young lady went to bed after dark. It was late now, and last night's dark time was almost Xu.
Cui 'er said that she heard some movement in miss Feng SI's room in the middle of the night. Assuming that the murderer had sent miss Feng Si back to the Feng family at that time, the longest time to assume was at Yin hour, it would not be enough time for the murderer to bring a corpse back to the Feng family from Qiyun temple.
