Burdened mentally rather than physically, Daneel started the slow, gruelling journey back to Graiton.
It had taken days to get from there to the beggar king's city, and to lead his pursuers away from the rest of his party, he had travelled in the other direction. That meant that he had a long way to go, and because he had to make sure that no one saw him on the way, the best estimate that the system gave him was that it would take 10 days, at least, to get back to his home island if he wanted to get there without letting anyone know who he was, or where he had gone.
