ust how any inkling of what was happening penetrated the pain-swept consciousness of the blind and deaf President could never be determined. Possibly a thin repercussion of Grim's cry, possibly an intuition that comes to sense-bereft men. But he had jerked spasmodically erect. There was a sharp tinkling as the weakened leg links broke. He threw himself in a queer, awkward movement forward, directly in the path of the tubed weapon. A blinding beam flashed out of the orifice, sheared through Peabody's middle as though he were cut cleanly in half with a gigantic knife. He toppled in two sections to the floor of the conveyor—released from all humiliation, all suffering.
At the same time two other things happened. Grim Morgan hit the guard like a crashing thunderbolt and Hilary's gun barked once. The monster tottered under the impact. A puzzled expression flitted over his pinkish eyes, a filmy sheath spread over them like a veil, and he fell heavily, a neat bullet hole square between his eyes.
Hilary shoved the gun back in his blouse, and stared alternately at the huddled form of the grotesque being and all that remained of Amos Peabody. The old President had saved his life at the cost of his own. Instinctively his hand went up in formal salute to the gallant old man.
Grim Morgan shook him by the shoulder.
"Man," he said quietly, "we have killed a Mercutian guard. Within the hour we shall be dead men too."
Hilary looked up at him sharply.
"A Mercutian," he echoed. "You mean—"
"That for three years now the Earth has been a conquered province of these devils from Mercury," Grim interposed swiftly. "We have committed the unforgivable offense and must pay for it."
