energy-draining feat, Post quipped...." He was halfway across the lawn before he realized the terror into which the grating radio voice had thrown him. He leaped for the branch over-hanging the fence, vaulted up with the risky help of a foot on the barbed top. A surprised squirrel, lacking time to make its escape up the trunk, sprang to the ground ahead of him. With terrible suddenness, two steel-jawed semicircles clanked together just over the squirrel's head. Jack landed with one foot to either side of the sprung trap, while the squirrel darted off with a squeak. Jack plunged down the slope to the rocky spine and ran across it, spray from the rising waves spattering him to the waist. Panting now, he stumbled up into the oaks and undergrowth of the first island, fought his way through it, finally reached the silent cove. He loosed the line of the Annie O., dragged it as near to the cove's mouth as he could, plunged knee-deep in freezing water to give it a final shove, scrambled aboard, snatched up the boathook and punched at the rocks. As soon as the Annie O. was nosing out of the cove into the cross waves, he yanked up the sail. The freshening wind filled it and sent the sloop heeling over, with inches of white water over the lee rail, and plunging ahead. For a long while, Jack was satisfied to think of nothing but the wind and the waves and the sail and speed and danger, to have all his attention taken up balancing one against the other, so that he wouldn't have to ask himself what year it was and whether time was an illusion, and wonder about flappers and hidden traps. When he finally looked back at the island, he was amazed to see how tiny it had grown, as distant as the mainland. Then he saw a gray motorboat astern. He watched it as it slowly overtook him. It was built like a lifeboat, with a sturdy low cabin in the bow and wheel amidship. Whoever was at the wheel had long gray hair that whipped in the wind. The longer he looked, the surer he was that it was a woman wearing a lace dress. Something that stuck up inches over the cabin flashed darkly beside her. Only when she lifted it to the roof of the cabin did it occur to him that it might be a rifle. But just then the motorboat swung around in a turn that sent waves drenching over it, and headed back toward the island. He watched it for a minute in wonder, then his attention was jolted by an angry hail.
