Earlier, Olivia had assisted him by bringing a sleeping bag, food, and water right up to the edge of the rock where he had made his little nest. It had become comfortable to a degree that was actively endangering his life; he was reluctant to move from this location that had already been made known to the enemy. As a first step toward abandoning it, he wriggled back to a spot from which he could not be seen from below, then devoted a few minutes to teasing a sleeping bag out of its nylon sack and loosely restuffing it into his parka. He pulled the hood up and made sure that it was packed tight enough to keep it round, then poked his sunglasses into it and wrapped a scarf around the lower part of its "face." The whole time he was doing this he was feeling a moderate sense of embarrassment at playing such a cheap trick. But he had read all the old propaganda stories about the snipers of Stalingrad and knew that they had achieved much with a repertoire of simple gambits such as this one. When it was complete, he crawled forward, pushing the effigy before him so that its head would pop into view over the edge of the rock long before Sokolov himself became exposed.
