Why not try the door, however? That would determine in a measure whether Yuri lied. But as Myles started to put this plan into effect, he was stayed by the sound of a human voice, a strange and raucous human voice.

Could he be dreaming? Had his mind given way under the strain of his many vicissitudes? For there were no human voices on Poros.

Yet there could be no mistaking the sound. It was not the radiated antennae speech of Poros. It was a real human voice smiting against his human ears. Cabot stood still in perplexity.

TREACHERY

“Myles,” said the voice, “show no signs of surprise. It is I, Lilla, speaking to you with my mouth, so that the antennae of Yuri may not hear. Neither can I hear, myself, which makes it difficult for me to talk thus, in spite of all my secret practice. Do not back up, to try the door, for there is a man behind you in the curtains. Remain where you are. When I raise my hand, you must wheel and fire. Then turn quickly back, lest Yuri escape us.”

Cabot stood aghast. He scarce took in the purport of the words. Was that raucous sound the voice of his lovely Lilla? Better, then, she stick to antennae speech for the rest of her days!

But there could be no doubt about it, for her lips were moving with the words.

Then up shot her arm. Instantly Cabot realized what she had said. He wheeled just in time to see a Cupian separate the curtains and make a rush at him. This newcomer wore the uniform toga of the palace guards, and held in his upraised left hand a sharp stiletto. How fortunate that it had not been a revolver, for with such a weapon he could have fired at Myles from behind the curtains.
