"I just love the way you reassure a girl, Mr. Cawdor," she said. "If these tunnels start to fill up with water, it'll be a million laughs."

Jak's voice floated back to them. "It goes under water. I figure it's mebbe a trap. I'm going through. If it's safe, or I can't get through, I'll come back."

Ryan pushed past the others and touched the boy's shoulder, feeling it slick with mud. "Don't try and be a fucking hero on this one, Jak. Don't push it too far. Remember that Doc and the girls, and Finn, won't be able to get as far as you can."

"Sure." The mane of tumbling hair, although matted and streaked with dirt, glistened white in the narrow confines of the tunnel.

Ryan, his eyes accustomed to the poor light, watched as the boy crawled to the point where the flat, leaden water waited. Jak took several deep breaths, then gave a quick thumbs-up sign. Slipping into the unknown deeps of the pool, he wriggled out of sight like an eel.

A feeble trail of bubbles burst to the surface, hung there for a moment, then vanished. To Ryan, the bubbles were a lingering reproach for allowing the lad to risk the dive. He counted fifty slow beats of his heart. Then he saw an ominous swirling in the water, as though some sinister creature were moving deep below them.

"There he is," Krysty said, pointing at a faint white blur in the darkness.

Jak burst out of the side of the pool, expelling air from his lungs in a wheezing gasp as he shook his soaking hair away from his face. "Easy. Go down coupla feet and swim straight for around fifteen feet. No more'n that. Air's fresher other side. Colder. More light."

"What about tracks?" Ryan asked.

"Can't see none. But I figure it's raining up top. Water streaming down passage."

"Best get it over," Krysty said.

"Yeah, lover. Let's... What's wrong, Lori?"

Huddled in her new fur coat, the girl shook as if she had an ague. When she tried to speak, her teeth chattered so much it was impossible to understand her.

Doc hugged her, then looked away from her to the faces of the others, seeing his own concern mirrored in everyone's eyes.

Finn broke the silence. "She can't fucking swim," he said quietly without anger. "That's it, isn't it, Lori?"

The girl began to cry, then buried her face on Doc Tanner's shoulder, which answered the question.

"I'll take her through," Jak suggested, standing up, muddy water pouring from his clothes. "But we best go quick."

Lori pulled away, backing against the wall of the tunnel, eyes wide and blank with terror, her right hand dropping to the butt of the pistol at her belt. Ryan saw immediately that she wasn't going to go through easy.

Which meant it had to be hard.

"Lori," he said, calm and friendly, stepping toward her, watching her fingers gripping the butt of the small Walther PPK blaster.

"No, no, no, no, no," she repeated, flat and dull, shaking her head.

"That's all right," he reassured her. "Nobody'll make..."

He watched her eyes, seeing her glance across to Doc Tanner for reassurance. That was the moment.

The punch jarred through his wrist and elbow, clear up to the shoulder. There had been no point in trying to pull it. The girl was in such an advanced state of panic that she could easily have gone for her gun. And then he'd have had to kill her. Better to lay her out cold.

Her teeth clicked together as she went over. His fist had hit her clean on the angle of her jaw, so that she was sent back up the tunnel, heels teetering, spurs jingling, before she crashed down, one leg kicking out in a residual gesture.

"You cowardly bastard!" Doc Tanner yelled, stepping toward Ryan and raising his sword stick.

"Don't do it, Doc," J.B. said gently. "Ryan did it for the best. We try and force her, someone'd get chilled. We leave her, she gets chilled on her own."

The old man turned away, eyes closed, shaking his head. "I had not thought... had not..." He turned back, moving to kneel beside the unconscious girl.

"Leave her, Doc," Ryan said. "No time. Finn, you and Jak drag her through. There's room?" he asked the boy.

"Easy. I'll hold hand over nose and mouth. Won't choke."

Finnegan and Jak plunged into the dark water, gripping the limp figure of the girl between them as they kicked their way out of sight. Ryan counted a hundred heartbeats, then gave the old man the nod.

"Go join 'em, Doc. And tell her I'm really sorry about hitting her."

"I accept that you were correct in your course of action, Mr. Cawdor, but you can scarcely expect me to relish it."

Hat jammed on his head, one hand steadying it, Doc Tanner vanished from their sight. Ryan, J.B. and Krysty waited for a few moments. The water at their feet swelled and surged, lapping at the toes of Ryan's combat boots.

"Fireblast!"

"What's?.." Krysty began, looking down. "It's rising. It's getting..."

"See you the other side," the little Armorer said, tucking his beloved fedora into the front of his coat as he jumped feet first into the pool. A trail of bubbles indicated his progress under the ledge of rock.

"The rain," Krysty said. "I can hear it. Hear it louder. Ryan... it's like thunder on..."

There wasn't time for her to finish the sentence. The pool began to foam and froth, a reddish scum appearing on its surface. Where it had begun to rise slowly, inching up the slight slope toward them, it now swelled wolfishly, clawing at their boots, forcing them back up the tunnel into the blackness behind them.

They hesitated. Already the water had risen at least two feet, pushing along a dozen feet or more. The power of the surge was frightening, bubbling like a monstrous cauldron.

"What d'you think, Lover?" Krysty asked. "Be difficult to swim through that now."

Ryan bit his lip in anger. Another half minute and they'd all have been through safely. It crossed his mind to wonder how the other five were on the far side of the pool. If the flash flood had this kind of awesome power, then what would it be like in the chamber beyond?

"Got to move back. No knowing how long this'll go on 'fore it subsides again. Could be a couple of hours. Come on."

He led the way. Now the light had virtually disappeared, and he felt his way along the slippery walls, hearing the thunder of the water behind them, imagining it pursuing them. The passage rose and fell, and Ryan wondered if the flood had sought out a lower level ahead of them where it would trap them.

He felt the tension of panic rising in his chest as his pulse and respiration thundered. His good eye probed the blackness ahead as he tried to remember the way the tunnel had gone and wondered whether there was any side trails to confuse them. Water lapped around his ankles, cold and glutinous, like the embrace of a dying sticky.

"You there, lover?" he called, shouting at the top of his voice against the rising roar of the torrent.

"Yeah, keep moving. Getting deeper."

The passage sloped down, and for a few moments the water was up to his waist, chilling his groin, making him gasp in shock. Then the passage jerked up again, so that the water only slurped at his boots. The floor was streaming, slippery and infinitely treacherous. The current was so fast that to fall would mean death in the shrinking darkness.

When the passage narrowed, he banged his head hard on the ceiling, stunning himself. "Watch your head," he screamed, hearing fear ride his voice.

Then the ceiling caved in, and someone fell on his shoulders. Fire lanced across his ribs from a knife or spear, as fingers clawed at his windpipe. The extra weight was enough to knock him off balance, and he slipped over, head plunging into the cold mud.
