He pulled her to the floor. The blanket swathed her head. He wrapped the other one around his own head, fold after fold. They lay, tense, waiting. Nothing happened. He thought how foolish they would look, lying on the floor with their heads swathed, if nothing at all did happen. He still did not move. He waited. A series of small sounds began in the back of the house, just vaguely audible through the blanket-folds. A chattering of windows, creaking and rattling of beams, clink of dishes. The sounds came slowly through the house toward them. _Chatter, rattle_--leisurely advancing. He knew then he'd guessed right. The sonic beam itself was pitched too low to hear. But it was sweeping the house. It hit them. Lyllin stirred suddenly with a small sound, and Kirk gripped her arm, holding her down. He knew what she was feeling. He felt it himself, the sudden shocking dizziness, the keening inside his head. Even through the swathings of thick blanket, the beam made itself felt. Without protection they'd already be unconscious. The shock passed. The beam was sweeping on to the front of the house. Kirk remained on the floor, his hand still holding Lyllin's arm. He'd used sonics himself. He had a pretty good idea of how this one would be used. He was right. The small, half-audible sounds of the house and its shuddering contents came walking back toward them. _Chatter--clink. Rattle--clink--_ It hit him again, and he set his teeth and endured it. And again it passed them, and once more the kitchen dishes started talking. Kirk suddenly thought of the unsuspecting Earth folk in the nearby farms, sleeping peacefully in their old houses, without ever a dream that in their quiet countryside, alien folk from the stars were pitted in a secret struggle that had this whole ancient planet as its prize. The sounds shut off abruptly. Kirk unwrapped his head, and twitched at Lyllin till she did the same. He made a warning motion to her, to keep down, and he himself crawled forward to the old living-room. He had the little shocker in his hand now. In a corner of the living-room, behind a grotesque old table, he waited. There was no sound at all. Then there was one. Footsteps, on the porch outside--coming fast and confidently to the door. A man came into the room. He wore a dark space-jacket and slacks, he carried a shocker, and he walked like a dancing panther. Kirk knew him. His name was Tauncer. CHAPTER VI Behind Tauncer came an older man, as gray and solid and rough at the edges as an old brick. He could have been an Earthman, and probably was. He was loaded down with a porto, and some other piece of equipment in a carrying case slung over his shoulders. Taking no chances at all, but allowing himself to feel a deep and vicious pleasure, Kirk fired from behind the table.
