Guards! Guards!
Dragons turn out to be less mythical than the Civil Service believed. In fact, everything the Town Watch believe is likely to be wrong, because it's that kind of movie and they're that kind of Guard. High-level, low-spirited officials make a monkey out of the librarian of Unseen University, which is not much of a challenge because the librarian is an orangutan. The perfect book to read while flying to an English provincial town, or back.
