Reverse Phone Detective Free

Curiosity kills the cat, and I was just so curios to know who's the person behind the number that texted my wife to meet him at the old place by the lake tomorrow afternoon. 3:00pm is actually working time and she told me there would be an important meeting tomorrow that may keep her late. The only thing on mind was to find out who's the caller, but I didn't wanna bother to get a private detective for I just need to know some simple facts quickly.

Who could provide me a clue or better satisfaction to bring me back?
