Chapter 22: The Flight in the Heather: The Moors

David and Alan hike for seven hours and come to the end of mountain range. Now they must decide which direction to go in. Appin, to the west, is crawling with soldiers. The land to the south is crawling with Campbells, and going north will not work for David, who wants to get to Edinburgh, and Alan who needs to get to France. So they decide to head east, though David again realizes that if they parted ways, they might both be safer. They must cross the moors, which are wide and flat, and they run a great risk of being seen, but they have no choice.

Half the time they must crawl on their bellies or run on their knees, and soon David becomes very tired. They rest at noon in a bush, and Alan takes first watch. When David takes his watch, he falls asleep, and awakes to discover soldiers coming near them. He wakes Alan, who quickly decides to head for a mountain, Ben Alder, in the northeast. This takes them past the soldiers, forcing them to run on their knees for most of the way. Just as they near the mountain they are ambushed. It turns out to be friends, men of Cluny Macpherson. The men lead them to Cluny's hideaway in the woods.

Chapter 23: Cluny's Cage

Cluny welcomes them to his home in Ben Alder. It is a hut made from trees, leaves and other natural things, and it serves as an excellent hideout. Cluny is a fugitive chief of a clan put down by the English government. He lives well in his small home, but he can hardly ever leave. He has been cooped up so long that has some strange habits.

After they eat, Cluny proposes a game of cards, but David declines to play, and makes a small comment about the immorality of gambling. Cluny takes offense, but Alan says that David is just tired. David sleeps away nearly two days, feeling somewhat ill, while Alan gambles and loses all their money, including David's. David is forced to ask Cluny for their original money back, since Alan's pride won't let him ask for it. Cluny is mortified that they thought he would keep the money, David is angry that Alan gambled it away and he has to swallow his pride and ask for it back, and Alan feels guilty for having gambled it all away.

Chapter 24: The Flight in the Heather: The Quarrel

Alan and David continue their hike through the woods. David is still angry at Alan, who is miserable, knowing he has done David a wrong. But David is very angry, and he cannot bring himself to forgive Alan. Alan apologizes, but David remains bitter. Alan offers, perhaps a bit childishly, to allow them to part, since he is "not very keen to stay where [he's] not wanted." David chides him, asking him whether he thought David would turn his back on a friend. Alan points out that he owes David both his life and his money now, which is clearly a burden to him, and asks that David realize that. David becomes angry with both himself and Alan, and becomes a little cruel.

They hike for many days. David becomes increasingly cold and sick, and remains angry with himself and Alan. Alan asks if he can carry David's pack, and David responds crossly. Alan takes this coldness from David as an excuse to think that they are now even, and even begins to taunt David as a Whig.
