The cop was hailing him; clever cop! All it had taken was a couple of full-throated yells and at once the cop had perceived that someone was in the park. But cleverer than any cop was Mooney.

Men from the future. Why, thought Mooney contentedly, no Mrs. Meyerhauser of the suburbs would have let me get away with a trick like that to sell her a freezer. There's going to be no problem at all. I don't have to worry about a thing. Mooney can take care of himself!

By then, he had caught his breath—and time was passing, passing.

He heard a distant confused yelling. Harse and the cop? But it didn't matter. The only thing that mattered was getting to the Nexus Point at one minute past one.

He took a deep breath and began to trot. Slipping in the snow, panting heavily, he went down the path, around the little glade, across the covered bridge.

He found the shallow steps that led down to the Vale.

And there it was below him: a broad space where walks joined, and in the space a thing shaped like a dinosaur egg, rounded and huge. It glowed with a silvery sheen.
