"I am Ulana," she said simply.
The stone door opened silently and Tiedus slipped in, closing it swiftly behind him. He stared at the girl and at the trussed-up figure of the guard.
"So!" he exclaimed; "this is the explanation." He breathed heavily as if he had run a long way, and his face was flushed with excitement.
"Why? What's wrong?" Blaine sensed a calamity.
"The Zara—she must have seen you in the crystal. She is in a murderous rage and has visited her wrath on the Tritu Anu. Even now Dantor is on his way to Ilen-dar in answer to her summons."
"Tiedus! I'm sorry. It is my fault entirely, but—but we heard Ulana cry out."
"You did quite right, Carson. I should have done the same myself. And actually it makes little difference as far as we Rulans are concerned. We had not long to remain in this life, anyway. It is only that your hiding place might be revealed; that our plans to outwit the Llotta will fail."
"You—you think she will make away with Dantor?"
"No; he is too valuable as a scientist. But the guards are awaiting her orders to repeat what happened in the Tritu Nogaru. She depends on the work of this laboratory a great deal, though it may be she will stay her hand."
