So they introduced the detective by showing his Sherlock-level observation and deduction skills to discredit him immediately. Very cool.
Saw someone saying Leo was the culprit and he showed MC and friend the statue so they recognized the wrong face but that would imply that Leo was the one to put the statue there in the first place which would be weird, would also be weird for him to push MC to investigate on his own as the credible and famous detective didn't suspect him. But then again, I guess Leo could be stupid for the plot...
