Ciaran had a hunch the safest thing would be to quietly trip him off into space. He resisted it, simply because knifing a man in a brawl was one thing and murdering an unsuspecting elderly man in cold blood was another. Later, he swore a solemn oath to drop humanitarianism, but hard. Nobody saw them. The Kalds and the people below were all too busy not breaking their necks to have eyes for anything else. Nobody came down behind them—a risk they had had to run. They were careful to keep a whole section of the descent between them and the slave gang. It was a hell of a long way down.
