he first human being they saw was one of the guards, in a black tunic. He was leaning against a wall, and he was a human being no longer. He looked as if he was asleep, but he was stone dead, with a placid look on his face.

Dick found a stairway and led the way up. He thought it ran up to the laboratory, but, instead, the room into which he emerged was the ante-room of the Invisible Emperor's audience hall. Six dead guards lay in a heap in front of the curtain, and they had died as unconcerned as their fellows, to judge by the pacific expressions on their faces.
