Straight up two flights of stairs led Nicol Brinn, taking three steps at a stride. Palpably enough the place was deserted. Ormuz Khan’s plans for departure were complete.

Into two rooms on the first floor they burst, to find them stripped and bare. On the threshold of the third Brinn stopped dead, and his gaunt face grew ashen. Then he tottered across the room, arms outstretched.
