"They did," Joan admitted readily. "They frightened me out of my wits. I screamed and they ran through the house and out the back way." The Mercutian was suspicious. "Hmm. Funny there's no sign of a struggle here. Nothing is upset." "They ran out the back way," the girl repeated tonelessly. "We'll see; but if you are lying...." He said no more, but the pause was significant in its implications. "I would not lie to the Magnificents." "Not if you are wise." He seemed to be the leader. He evidently turned to his companion, for there issued a flood of throaty consonants to which the other grunted once. Then the listeners heard his heavy stamping as he walked through the house to the rear. A door whirred; he had gone out. * * * * * The remaining Mercutian said suddenly: "He won't find them." "Why not?" Joan asked, a bit tremulously. The Mercutian laughed harshly. "Because you lied. You've hid them in the house." Hilary heard Joan's sudden sharp intake of breath. "No, no, Magnificent," she cried. The Mercutian laughed again--a hard cruel laugh. There was no mirth in it. "All Earthwomen are liars. I know where you hid them. In your bed chamber. The trick is too old already. We may not be able to see through the lead curtains, but we can break down the door. I warned Artok not to permit the use of the lead curtains, but he has a soft streak. He listened to the women's pleadings for privacy. Privacy, pah! A cloak for conspiracies, that's all it comes to. When Gurda returns, we search upstairs and drag out your rats from their hole." He laughed smugly, pleased with his own cleverness. "It is not so." Strange how calm Joan sounded. "They are not in the house. Only my dying mother is here. She is bedded upstairs. The doctor ordered absolute quiet. The slightest noise would be fatal." The Mercutian sneered. "We'll take a look at that dying mother of yours right now." "You mustn't," the girl panted. "She will die, I tell you." "And what does it matter to me?" There was the sound of a struggle, a sharp cry, followed by a dull thud. * * * * * Hilary was out through the door like a flash, down the corridor to the head of the stairs with automatic extended. The monster Mercutian was coming heavily up the treads. They saw each other simultaneously. The Mercutian's pink eyes turned a vicious red; the tube dangling in his hand jerked sharply up. Hilary squeezed the trigger. The gun barked. The Mercutian spun half around with the force of the tearing bullet. The deadly beam from his weapon slithered over the wall, searing a great molten gash in the crystal. He was badly hurt, but he did not fall. Howling with pain and rage, he slewed himself around again, pointed his sun weapon unsteadily upward. Hilary let him have the other slug. The big body jerked, and fell backward with a crash to the bottom of the stairs, there to lie oddly contorted and still.
