jagged sharp-edged shadow of a Devil's Egg. Its eyes, like shiny pin-heads of obsidian, were on a level with his. It was a red-scaled creature, about three inches long, combining the most significant characteristics of an Earth crab and an Earth ant. Its claws were tiny razor-edged traps on the ends of wire-thin appendages. Even at this distance, Monk saw that its mouth was open—whether in awe or in anticipation of a meal, he did not know. The Aab rose on its six rear legs as if trying to stretch its dark red body into a position of better vision. It rubbed its fore-claws together. Sharpening them, perhaps? Monk shivered. For the first time since his arrival on Mars twelve years ago, Monk felt fear. Till now, he'd met no adversary that his strong, bull-necked body could not subdue. Ordinarily, he'd dispose of an Aab by a squishing stomp of his boot. And he'd flower the naked grave with a squirt of tobacco juice. But now it was as if he were bodiless. His broad shoulders, sinewy arms and barrel-chest seemed buried a thousand miles deep in the very bowels of the planet. He was a helpless freak, a living, sliced-off head on an endless platter of red sand. Fear was an icy bauble in his mind, rising, swelling, forcing out all other thought. "Go 'way!" he yelled. The Aab's claws fell to the sand. Monk saw the menacing glint of the needle-like tongue in the creature's black, open mouth. Aabs were carnivorous, he knew. They especially relished the soft, tender places of the human body—the lips, eyes, tongue. Ten minutes of attack by a hundred Aabs would transform a man into a white, clean skeleton. About the bones, the Aabs would lie prostrate, too stuffed to move, their bodies swollen to thrice their normal size. "Get out of here!" he screamed. The Aab retreated a few inches, backing into the shadow of the Devil's Egg. "Go on! And keep going!" The Aab turned and began to creep away. It responded readily to Monk's commands.
