They were walking back toward the great rotunda, and, as they entered the conservatory, the crowds of men and women stared at them curiously. They had paused to inspect the statue of a massive stone dragon when a young officer in glittering uniform approached and addressed Johnston.
“Follow me,” he said simply; “it is the king's command.”
The American started and looked at Thorndyke apprehensively.
“Go,” said the latter; “don't hesitate an instant.”
Poor Johnston had turned white. He held out his hand to Thorndyke, “Shake,” he said in a whisper, not intended for the ears of the officer, “I don't believe that we shall meet again. I felt that we were to be parted ever since that medical examination.”
Thorndyke's face had altered; an angry flush came in his face and his eyes flashed, but with an effort he controlled himself.
“Tut, tut, don't be silly. I shall wait for you round here; if there is any foul play I shall make some one suffer for it. You can depend on me to the end; we are hand in hand in this adventure, old man.”
Chapter VII.
Johnston followed his guide to a flying machine outside. He hesitated an instant, as the officer was holding the door open, and looked back toward the conservatory; but he could not see Thorndyke.
