Sally left the library with her arms full of books. She didn't really register how dark it was now, still somewhat dazed over the whole Shakespeare business. She wandered in the general direction of the hotel, not hurrying. She could see lights up ahead, and this finally made her realise that she was wandering alone in the dark with her arms full of books. Alone in the dark wasn't a new thing, but the armfull of books wasn't very practical. If anyone did threaten her, she supposed she could throw the complete works of Oscar Wilde at them. Not that anyone necessarily would, she supposed.

She heard footsteps behind her and to her left, and turned, flashing a wide smile, but carefully separating the topmost and heaviest book just in case.
