King quickly extinguished the cressets, leaving the room in darkness. Then together the two groped their way to the door. Opening it a little, King looked out. The corridor was empty. He drew Fou-tan into it and closed the door behind him. To the next door in the corridor he stepped and tried it; it was not locked. He could just see the top of a flight of stone steps leading down into utter darkness. He wished that he had brought one of the cressets, but now it was too late. He drew Fou-tan within and closed the door, and now they could see nothing.

"Where does this lead?" asked Fou-tan in a whisper.

"It is the King's private passage to the garden," replied the American, "and if I have made no mistake in my calculations, the other end of it is guarded by a sentry who will pass us with a wink."

As they groped their way slowly down the steps and along the corridor King explained to Fou-tan the subterfuge he had adopted to obtain a place upon the guard that night and that he had particularly noticed the little door at the end of this wing of the palace and when the major-domo had told him of the private passage leading to the garden he had guessed that it ended at this very door. "The sentry there," he had concluded, "is from my own barracks and knows the story. That is why you must be a little slave girl to-night, Fou-tan."

"I do not mind being a slave girl—now," she said, and King felt the little fingers of the hand he held press his own more tightly.

They came at last to the end of the corridor. In the darkness King's fingers ran over the surface of the door in search of bars and bolts. The fastening, which he found at last, was massive but simple. It moved beneath the pressure of his hand with only a slight grating sound. He pushed the door slowly open; the fresh night air blew in upon them; the starlit heavens bathed the garden in gentle luminosity. Cautiously King crossed the threshold. He saw the warrior upon his post without, and instantly the man saw him.

"Who comes?" demanded the sentry, dropping his spear-point on a level with King's breast as he wheeled quickly toward him.

"It is I—King—of Vama's ten. I have found the slave girl of whom I told you, and I would walk in the garden with her for a few moments."

"I do not know you," snapped the warrior. "I never heard of you or your slave girl," and then it was that King realised that he had never seen this man before—that the sentries had been changed since he had entered the palace. His heart sank within him, yet he maintained a bold front.

"It will do no harm to let us pass for a while," he said, "you can see that I am a member of the guard, as otherwise I could not have gained access to the King's house."
