Leave it here

Smiling to yourself you leave the photo on the desk of the library, summoning a new mobile phone into your hand and writing the number on the photo with a note to call you.

With that job done you glance around the library, spotting Emma still hard at work further back in the building and look forward to her reaction to the photo, although there's no knowing how long it'll take for her to find it.

You consider maybe popping out to investigate elsewhere while waiting for her to call, although having said that, waiting to see her reaction could be interesting.
