Please- have ANOTHER eavesdropping scene!

Truly brilliant writing. How do we have the main character find out the villain's intentions? Oh- have her walking underground and overhear a conversation by the pool.

Wait, how do we have the villain figure out that the hero has discovered the evildoers true intentions? I know- have her drive by while she's talking to someone else? Have her overhear a conversation in the rec room, blah blah blah.
