“Boo!”

Although, this may not be his evil lair for sure because as stated above it's too easy for public access and also it was not even close to looking so 'evil' like at all. In fact this place looked decent actually.

But! It is still, again as stated above, the place where he spends most of his time. So even if he's some evil genius to be slipping away with his dirty deeds all this time, he is still a human which we all know ,means, he is bound to slip up!

No matter how small or big, he must have made a mistake at some point. He must have left something she could find, some smallest of details that may not be as big enough to put him to jail as that recording was, yet still at least it could serve as a substantial incriminating evidence, enough to stand in the court of law to start up an official investigation against him.
