to attack you?"
"It would be the last thing you ever did, Mr. Grimes."
He laughed grimly. "I don't think I'll try it out, Your Highness."
"You'd better not. But would you like a demonstration?"
"Not on me."
She stopped, holding herself stationary in the water with gentle movements of her long, graceful limbs. She pointed with the hand holding the gun. "Look! Do you see the rock ogre?"
"The what? I see something that looks like a slime-covered rock."
"That's it. Perhaps the only really dangerous denizen of these waters. Native to Australis. Excellent eating, properly prepared. That's why we introduced it."
"It looks innocent enough."
"But it's not. Keep well back and watch closely."
She swam toward the thing. Then, with explosive suddenness, three triangular flaps sprang back on the top of the rough shell and, uncoiling with lightning rapidity, a thick stalk shot out straight at the girl, a glistening limb tipped with a complexity of writhing tentacles and gnashing mandibles. Grimes cried out in horror and pulled his useless knife, but he was not fast enough, could never have been fast enough.
The pilot fish were there before him, flashing past him at a speed that, even under the water, produced a distinct whine. One of them dived into the orifice from which the stalk had been extruded, the other attacked the ogre's head. It was over almost as soon as it had been begun. Mere flesh and blood, from whatever world, could not withstand the concerted onslaught of the little, armoured monsters. Only seconds had elapsed, and the girl was hanging there in the water, laughing, while the pilot fish frisked around her like dogs demanding an approbatory pat. An unpleasant, brownish mist was seeping up from the base of the stalk and from the debris of torn and severed tentacles, still feebly twitching, and broken mandibles at the head of it.
Grimes was sickened. It was not by the death of a dangerous (and, he had been told) edible creature, life owes its continuance to the destruction of life. It was by the genuine pleasure and amusement in the girl's high, clear laughter. But blood sports, he told himself dourly, have always been the favorite recreation of the so-called aristocracy.
He said, "I must be getting back to work. Your Highness."
He started off in what he thought was the right direction, but the water was heavily befogged by the ichor from the dying rock ogre. He did not see the other rock, the shell, rather, until he was almost on top of it. He screamed and made a frantic effort to avoid the terrifying head that shot out at him. He felt a sharp pain in his side as something grazed his body, heard a dull thunk followed by another. The rock ogre seemed to go mad, writhing violently. The thick stalk caught Grimes a flailing blow in the belly, knocking him well clear. He caught a glimpse, vivid, unforgettable, of Marlene, an underwater Artemis, with her gun raised for another shot.
And then the pilot fish swept in to finish the job.
Chapter 14
He sprawled on the muddy bottom, his hand pressed to the rent in his suit, the rent in his skin. He could feel the warmth of blood. He did not know how badly he was injured, but, at this moment, the imminence of suffocation was of far greater importance than loss of blood. He feared that the pipes from his liquid air tanks to his helmet had been buckled or severed and then, agonisingly, he was able to breathe again. It was the blow to the stomach that had knocked all the air out of his lungs.
She was hanging in the murky water looking at him, her stubby weapon pointing directly at him. A woman with a gun can be a frightening sight; a naked woman with a gun is always clothed in deadly menace.
Grimes whispered hoarsely, "Put that down!"
At first he thought that she had not heard him, then, slowly, she let her hand fall until the muzzle, from which protruded the lethal head of a new dart, was directed downward.
She muttered, "I'm sorry . . ."
