"You need something to cling to," she heard Madge say. "Dr. Kometevsky was the only person who ever had an inkling that anything like this might happen. I was never a Kometevskyite before. Hadn't even heard of the man."

She said it almost apologetically. In fact, standing there so frank and anxious-eyed, Madge looked anything but a fanatic, which made it much worse.

"Of course, there are several more convincing alternate explanations...." Theodor began hesitantly, knowing very well that there weren't. If Phobos and Deimos had suddenly disintegrated, surely Mars Base would have noticed something. Of course there was the Disordered Space Hypothesis, even if it was little more than the chance phrase of a prominent physicist pounded upon by an eager journalist. And in any case, what sense of security were you left with if you admitted that moons and planets might explode, or drop through unseen holes in space? So he ended up by taking a different tack: "Besides, if Phobos and Deimos simply shot off somewhere, surely they'd have been picked up by now by 'scope or radar."

"Two balls of rock just a few miles in diameter?" Madge questioned. "Aren't they smaller than many of the asteroids? I'm no astronomer, but I think' I'm right."

And of course she was.

She swung the book under her arm. "Whew, it's heavy," she observed, adding in slightly scandalized tones, "Never been microfilmed." She smiled nervously and looked them up and down. "Going to a party?" she asked.

Theodor's scarlet cloak and Celeste's green culottes and silver jacket justified the question, but they shook their heads.

"Just the normally flamboyant garb of the family," Celeste said, while Theodor explained, "As it happens, we're bound on business connected with the disappearance. We Wolvers practically constitute a sub-committee of the Congress for the Discovery of New Purposes. And since a lot of varied material comes to our attention, we're going to see if any of it correlates with this bit of astronomical sleight-of-hand."

Madge nodded. "Give you something to do, at any rate. Well, I must be off. The Buddhist temple has lent us their place for a meeting." She gave them a woeful grin. "See you when the Earth jumps."

Theodor said to Celeste, "Come on, dear. We'll be late."
