A mysterious phonecall

Re: A mysterious phonecall

What kind of surprise can be given in a library ?
If he wanted to surprise her with some gift he could hide it somewhere in the home and ask her to go look for something and get surprised. Plus in a library you cannot show emotions you have to hush hush.
Now a party cannot be planned in a library .

It is something big , BIG , BIG or something very trivial.
