"Huh?" asked Iimmi.
"Argo, I mean your sister, told me they had managed to kill one of the kidnapers, and it melted the moment it died."
"We couldn't control the whole mass," she explained. "It really doesn't have a mind. But, like everything alive, it has, or had, the double impulse."
"But what did kidnaping you accomplish, anyway?" Iimmi asked.
Argo grinned. "It brought you here. And now you're taking the jewels away."
"Is that all?" asked Iimmi.
"Well," said Argo, "Isn't that enough?" She paused for an instant. "You know I wrote a poem about all this once, the double impulse and everything."
Geo recited:
"By the dark chamber sits its twin,
where the body's floods begin,
and the two are twinned again,
turning out and turning in."
"How did you know?" she asked.
