Undercover photography (done badly)

This is my attempt to take a photo in the library, without the librarians noticing. Umm, didn't quite work out. I thought I was being clever by waiting until the end of the day to take the photo. My reasoning being that the place would virtually empty so no one would notice. I forgot that just because there were less people using the library it didn't mean that there would less staff, and they would have little to do but wait for me to finish. But I will succeed!
