章節 833: Dead End

"There's nothing wrong with the door!" Cui Lizhu said. "I also checked the door mirror, and it showed no signs of being tampered with whatsoever. Moreover, this house has no back windows, the chimney is not big enough for ordinary people to come through it, and none of the windows were broken. If the door was really locked from the inside, it was indeed what you call a 'locked room crime!'"

Zhang Jingfeng grabbed Han Kuan's clothes as he yelled, "Then... What are you waiting for? Figure it out! Who else could be the murderer besides Han Kuan?"

"Um... Are there any secret doors in your house?" Cui Lizhu asked Han Kuan.

"No." Han Kuan shook his head.

Cui Lizhu suddenly clapped her hands. "Okay… That settles it! There can't be anyone else involved except for this couple!"

When Cui Lizhu spoke, Zhao Yu got up from the bed and walked to the windowsill in the inner room. The curtains were pulled open.
