"Hello?" and I look around to see a woman I do not expect to be Lydia looking around one of the shelves. "Do you need some help?"

"That would be very kind, if you can," I say. "Do you happen to know if there's any place in particular I should leave these? I told Mrs Stephanides that I'd see what I had that might be useful, but I confess I didn't set a time to see her." I smile a little. "And I don't know if she'll be in today."
