Secondly, when in the rest of the Library, and having had a good read of whatever takes her fancy, Eileen then indulges in what we would call people watching. This does not go down well. Eileen never has been subtle. If someone catches her interest, they will know it soon enough as their sense her gimlet gaze on them. This has been a hangover from Eileen's catch the magically criminal days as this gaze had often caused the more nervous criminal type to give themselves up and confess all. Eileen found it saved a lot of time but finds it difficult to switch the gaze off again.
Thirdly, Eileen will often use the Library as a meeting place to talk with Hanastrew and other members of the fairy squad. This does annoy the Librarian. There are some people you just don't say "Shush" to!
