Sit at a table next to them.

Slowly and without looking at them for just a moment you sit at the table next to them. Pretending to be occupied with your phone you listen to their conversation.

Despite that they almost whisper you can hear them talk quite clearly.

“So are you sure the police is not aware of this deal? I feel a bit suspicious dealing with these Carnival figures“

The man replies calmly as he talks to the women.

“No worries, according to my sources they are quite reliable, they have never failed to deliver“

A short pause and then the women continues to speak.

“Good, so we will meet them and then will make the deal, if you are right this will make us rich“

As you listen you realize this is some big, criminal enterprise and they might know more about the disappearance of your daughter.
