In the wall, opposite the window, he discerned a doorway and crossing to it he saw that it opened into a narrow corridor, running parallel with the length of the room. Looking up and down the corridor he discerned faint patches of light, as though other open doorways lined one side of the hallway. He was about to enter upon a tour of investigation when the noise of something scurrying along the floor of the corridor attracted his attention, and looking back to his left he saw a dark form creeping toward him. It stood about a foot in height and was, perhaps, three feet long, but in the shadows of the corridor it loomed too indistinctly for him to recognize its details. But presently he saw that it had two shining eyes that seemed to be directed upon him. As it came boldly forward Tanar stepped back into the room he was about to quit, preferring to meet the thing in the lesser darkness of the apartment rather than in the gloomy corridor, if it was the creature’s intent to attack him. On the thing came and turning into the doorway it stopped and surveyed the Sarian. In his native country Tanar had been familiar with a species of wood rat, which the Sarian considered large, but never in all his life had he dreamed that a rat could grow to the enormous proportions of the hideous thing that confronted him with its bold, gleaming, beady eyes. Tanar had been disarmed when he had been taken aboard the Korsar ship, but even so he had no fear of a rodent, even if the thing should elect to attack him, which he doubted. But the ferocious appearance of the rat gave him pause as he thought what the result might be if a number of them should attack a man simultaneously. Presently the rat, still standing facing him, squealed. For a time there was silence and then the thing squealed again and, as from a great distance, Tanar heard an answering squeal, and then another and another, and presently they grew louder and greater in volume, and he knew that the rat of the Korsar dungeon was calling its fellows to the attack and the feast. He looked about him for some weapon of defense, but there was nothing but the bare stone of the floor and the walls. He heard the rat pack coming, and still the scout that had discovered him stood in the doorway, waiting.
