Get Wind of sth. 听到……的风声

[ar:G：Sunshine, you got a bad case of puppy love?]
H：I don't think we should do anything out of the ordinary.
A：Yeah, she's right. It's imperative that we carry on as usual...
M：What am I supposed to do? Just go about my life as everything is fine?
A：That's exactly what you should do.
H：Yes, go skiing, go to parties, act normally.
A：Don't you see, honey? We can't let on that anything's wrong. If the press or the authorities get wind of this, the kidnappers may panic.
