Annie stopped partly out of pity for the despot, and partly because Alec stopped.

Alec stopped because he was the author of the situation--at least he never could give any better reason.
At length Mr Malison lifted his head, and made a movement towards his hat.

He started when he saw the two standing there.

But the moment he looked at them their courage failed them.
"Rin, Annie!" said Alec.
Away she bolted, and he after her, as well as he could, which was not with his usual fleetness by any means.

When Annie had rounded a corner, not in the master's way home, she stopped, and looked back for Alec.
