The Heckler & Koch went clattering into the water. Ryan couldn't breathe. Something held his head under the slime, as a knife or spear sliced across his stomach and cruel fingers tried to rip out his throat. Feeling skins with his hands, he guessed it was an ambush from the stunted muties who had been trailing them since they had arrived in the complex. It had crossed his mind that the muties had probably built the maze of tunnels scaled down to their dwarfish bodies. This one had been hiding in a dugout in the celling when it had heard them back away from the rising flood.

Ryan's only edged weapon was the long cleaver that was sheathed at his belt, useless for such close combat. He half rolled, kicking out to try to gain a footing. Pushing against the walls of the tunnel, he threw himself back, feeling the satisfying crunch as he smashed his opponent into the jagged stone.

The grip on his throat loosened for a moment, and Ryan was able to reach behind him, grabbing under the skins between the man's thighs. Feeling the softness of the dwarf's genital sac, he squeezed and ground it as hard as he could, digging his nails in. In the noise and confusion he wasn't sure, but he thought he heard a scream. Finally the mutie was off his back, and Ryan straightened, his head at last clear of the torrent. There was a flickering yellow light from the hole above him where the ambush had been launched, and he made out the head of another man, staring down at him. A spear lunged toward him, and he dodged, seeing the first mutie approach again, face contorted with pain, mouth open, long wolflike tusks gleaming golden.

One of the strange sectioned spears was in his right hand, jabbing at Ryan's belly. The blow wasn't hard to parry with the side of an arm. Ryan blinked — mud had gotten in his eye. He watched his enemy. The water was just above his knees, swirling and tugging, making it difficult to maintain balance. The best thing to do, he figured, was to get in close and use his superior height, strength and weight in hand-to-hand fighting.

The lance darted out again, and Ryan took a superficial cut on his left hand from the jagged, barbed ivory tip. He felt the warmth of fresh blood trickling down inside his coat from the two wounds across his ribs, but nothing seemed too seriously damaged. Beyond the mutie's shoulder he caught a flicker of movement and the flash of brilliant crimson hair. Whatever problems Krysty might be having, there was nothing he could do to help her. Not yet.

"Come on, you evil little fucker," he breathed, watching the flat, blank face, seeing nothing in the mud-colored eyes.

Out came the spear, but he was ready, moving easily like a dancer inside the thrust, grabbing the wooden haft and pulling the mutie toward him.

Above the sound of the water, he heard the mutie utter a squeaky cry. Ryan swung a punch at the open mouth, but the mutie was quicker, ducking and grappling with him. A foot hooked behind his ankle, and Ryan fell again, dragging at his opponent's arm. Once again he swallowed a mouthful of the muddy stream, flailing and kicking at the mutie.

The creature tried to butt him, and Ryan turned, biting the side of the attacker's neck. His teeth slithered off the wet skin, and he tasted grease and sweat and wood smoke. He locked an arm around the scrawny neck, simultaneously managing to pull him closer and heave himself from the water, sucking in a great gasp of fresh air.

Despite being much smaller and lighter than Ryan, the mutie was a vicious and cunning fighter, throwing Ryan off balance for a third time, hands scrabbling toward his groin. With great effort, Ryan turned so that the clawing fingers tore at the side of his thigh rather than at his scrotum.

Again he dipped his head, seeking the mutie's throat with his teeth, finding flesh and clamping his jaws shut. An artery pulsed between his lips as he drove his teeth through skin into flesh. Blood, salty and warm, spurted into Ryan's mouth.

The mutie screamed like a pig being gelded, then thrashed and kicked. One hand came up toward Ryan's face, attempting to rip and pulp his one good eye. Ryan seized the wrist, squeezing it and feeling the thin bones flex and snap like twigs.

He clamped his teeth together with great force, spitting out blood from the corner of his mouth, working through the beating wall of gristle that protected the carotid artery in the throat. The mutie, even with a broken arm, wasn't down, and he nearly succeeded in kneeing Ryan in the groin, instead delivering the blow to his leg.

Ryan's head bobbed as he chewed into the man's flesh. As he finally severed the artery, there was a great burst of wetness and heat that nearly choked him. He opened his mouth and pushed away from the yelping mutie, seeing the lifeblood, almost black in the tunnel's dim light, spout clear to the ceiling.

The dying man was carried away by the surging torrent, his broken arm waving crookedly as he whipped around a sharp corner and vanished.

Ryan stooped to retrieve the fallen blaster, glancing at the trap in the ceiling, seeing someone still stooped there. Without hesitation he pulled the trigger, firing a short burst. There was a cry of pain, and the mutie fell backward out of sight.

"Any more?" a voice shouted from behind him.

"Can't fucking tell," he shouted back. Wading toward Krysty, who was stooping under the low roof a few yards away, it struck him that she was in a peculiar, lopsided position.

"Took your time there, lover," she called. "Getting too old for all this."

"Didn't know it took long. Shows how time hisses by when you're having fun. You hurt your leg?"

"No. Had a mutie come after me, but I neck-chopped the little bastard. Knocked him under water. Then, 'fore I knew it, I had the heel of my boot jammed tight on the back of his head. He's still down there. Figure he's 'bout had enough?"

"Let go and find out."

Krysty moved away, and the sodden corpse of another mutie rose slowly to the surface, face up, eyes and mouth open. It began to drift in a circle before the girl pushed it, allowing the current to carry it off and follow the other chilled body.

Ryan took Krysty's hand, holding her tight. "Done good," he said, leaning and kissing her on the cheek. "You get hurt?"

"Some. He had one of them folding spears, like Whitey got. It caught me 'cross the belly."

"No serious damage... lower down?"

"No. Not that I noticed. Bled a little. The son of a bitching fucker tried to rip my balls off. That made me real angry."

Krysty stared up at the circle of yellow light. "Could be more of 'em up there?"

"I reckon they'll have had it on their toes when the shooting started. I'll lift you and you take the blaster," he said, handing her the gray G-12 caseless.

"Water's stopped rising."

"Yeah. But if'n that passage goes above, we can find a way out and mebbe link up with the others outside. Save us waiting down here. Truth is, I don't much care for this crawling on my stomach under five miles of mud and stone. I'm an out-in-the-open sort of person."

"Me, too, lover."

Ryan steadied himself against the wall of the tunnel, cupping his hands so that Krysty could step up, balance and stand on his shoulders. It would give her the height to look through the open mouth of the tunnel above and blast anything that moved.

If it didn't blast her first.

Her boots were slippery, and she nearly fell. She grabbed his head to steady herself, her fingers tangling in his hair, which made him yelp.

"Watch it," he moaned.

"Keep still. You're rocking around like an aspen in a hurricane."

Then she was up on his shoulders. Ryan braced himself, wincing in expectation of hearing the roar of a gun from some hidden enemy. But all was quiet. She half turned, the heels of her cowboy boots scraping his ears, which made him wriggle again, then she pushed upward, and her weight was off him. He looked up and saw her legs vanishing into the hole above, momentarily blocking the light.
