Introducing some interesting and significant characters if you read this series in the appropriate order! (Oops.)
The direction of this sub-series has been set with the leisurely romantic life of Cpt. Vimes, the Patrician's interest in Carrot, and the beginning of the Night Watch's upwardly mobile journey in the esteem of the citizens of Ankh-Morpork. The Librarian gets deputized and there are a few inadvisable arrests made. The story is intermittent with snarky commentary about the human condition —I'm not super with-it concerning philosophy (and really, who would want to be?), but think: T-Hobbes— and tied up with a pretty red bow that possibly symbolizes quite a lot of fire.
'If there was anything that depressed him more than his own cynicism, it was that quite often it still wasn't as cynical as real life.'
