Dustfinger asks where Mo is off to in such a hurry; apparently the last time Mo left, it took Dustfinger four years to track him down.
Mo says he's leaving for the same reason as last time, then Dustfinger asks for a lift, saying he doesn't want to face Capricorn's men.
Curious, Meggie asks who Capricorn is, and Dustfinger is shocked that Mo hasn't told her yet. Mo explains that it's too dangerous for her to know.
Dustfinger tells Meggie that Capricorn likes watching people suffer, and that Mo has something Capricorn wants. Oh goodie.
Before they leave, Dustfinger introduces Meggie to an animal he gets out of his backpack, a little furry critter that Meggie identifies as a marten. Except it has horns.
As they're driving, Meggie asks Mo what Capricorn wants from him. The answer is surprisingly simple: a book.
