-Yuri-
I went back inside to look around again. I carefully examined the glass box. I even took off and put on my glasses repeatedly just to see if there was any difference in how the glass box looked with or without them.
What did Kuya Xian see to figure out the truth behind this case?
All of them had airtight alibis. No potential suspects, to be honest. How could the culprit have stolen the trophy if both the glass box and the office were locked, with no spare keys at all?
Airtight alibis. Locked room. Locked box. Hallway entrances. But how? Who?
Rosemary was in the cafeteria-everyone can verify her alibi. Francis was found by me, and I have no idea why he made such a mistake that made him a potential suspect. Watt was being chased by the principal's men. Simon was with the principal and saw someone running in the hallway.
Two entrances. One was muddy, and the other was clean. Wait... that's it!
I peeked outside the office and looked at their pants and shoes.
Two were wet, and three were clean. Think, Yuri! Think!
I looked around again and engraved every detail in my mind.
Pen. Painting. Glass box. Table. Meter stick. Papers. Wait... Hold on... I got it! I know who the culprit is. That person tricked all of us!
