Conan took a deep breath and calmed his racing heart.
Looks like my attitude toward Vodka caught Jiang Xia's attention after all, Conan muttered inwardly. No, I can't keep relying on being a child and let my guard down with my facial expressions—I'm a Great Detective. I should be good at disguising myself. What kind of Great Detective keeps letting people spot his flaws?
After briefly reflecting on his mistake, Conan ran to the window, stood on tip-toe, and looked outside, changing the subject. "Mr. Yamada's room is on the 7th floor... Huh? Why is there a room over there without curtains?"
Jiang Xia walked over and looked to the side—the building connecting the two parallel towers was not used much, and even during the day, most of its rooms had their curtains drawn.
Yet one room on the same floor was different. It had no curtains, and from here, they could vaguely make out various pieces of equipment neatly arranged inside.
Jiang Xia's gaze swept back and forth among the three rooms. "The angle is perfect."
It was as if lightning flashed through Conan's mind. His eyes lit up, and he reached out to push open the window of this "crime scene." "I see! In the darkness of night, the glass reflects like a mirror against the dark background—if this room's window is opened outward and pushed to a certain angle, it becomes a mirror, reflecting the scene in that room into Mr. Yamada's ward."
He pointed at the curtainless room behind them. "In other words, the crime scene Mr. Yamada saw wasn't this room directly across from him—it was that room over there!"
Jiang Xia nodded. "Let's go take a look."
The two left this false scene, turned a corner, and arrived at the real one.
