He might have done better to ride back by himself in the night, secretly, risking the bat-birds and reptiles and anything else that might be tempted to attack a lone rider. He would far rather risk his own neck ten times over than risk a panic among the Kargoi that could leave them helpless in the face of their enemies.

Blade was able to get some use out of his unwanted escort by making the warriors help him butcher the dead reptiles. At first the warriors drew back at the idea of cutting up two thousand tons of rapidly-decaying corpses in the hot sun. The smell alone already lay across the shore like a fog.

Blade ignored their protests and hesitations. He and Paor and Naula and a few other willing spirits stripped off their clothes, drew their swords, and went to work. After a little further hesitation, the rest of the warriors joined in, except the few on guard duty. They could not refuse to follow the lead of the hero Blade, or refuse to go where even Blade's woman went.

The work was every bit as gruesome as Blade expected. He was glad he hadn't eaten any breakfast. Most of the warriors didn't have stomachs as strong as his. Blade felt sorry for them, but he wasn't too unhappy to see them dropping out one by one. There were plenty of hands left to do the necessary work, and fewer eyes to watch him.

It was soon clear that the reptiles could be put to all sorts of uses. Their scaly hides made excellent body armor, shields, and helmets-heavy, smelly, and hot, but tougher than boiled leather and almost as tough as mail. Their bones came in all shapes and sizes, from tiny ones that could be carved into buttons, through larger ones that would make good axe handles, to the ribs that were as tall as a man and would make good roofbeams for fair-sized huts if the Kargoi ever had a chance to build any.

The claws and teeth would make excellent arrowheads and speartips-not as hard as metal, but more easily replaced and hard enough to deal with most human opponents. The internal organs were too far gone in decay to be much use. Taken from a freshly-killed beast, on the other hand, thoroughly cleaned, and cured in the sun, they would make large, sturdy bags and bottles.

Blade hacked and slashed, pried and pulled, splattering himself from head to foot with blood and filth until he looked like something found on the floor of a hutcher's shop. Even if the other men had been watching him every minute, they wouldn't have seen anything suspicious. He carved his way deeper and deeper into the decaying bodies without finding anything that shouldn't have been there in a normal beast.

At last Blade asked everyone to stand back and leave him alone for a short time. It was the custom among the English, he said, to offer the brain of a slain animal as a sacrifice to the Earth Wisdom. It was improper for anyone but a warrior of England to witness the sacrifice.

The few warriors still on their feet were more than happy to leave him alone, out of respect for his customs and out of a great desire to get away from the acres of reeking carrion. No curious eyes were around when Blade went to work on the skull of the most intact of the reptiles. That was the most likely place left to find some trace of whatever intelligence might lie behind the beasts' attacks.

Blade closely examined the hide stretched over the huge skull. Any scar, any unnatural bulge might give him a clue. He looked until his eyes were watering and his fingers raw from prodding the scaly hide. All he could find was one strip about a foot long and a couple of inches wide, where the hide seemed a little smoother than elsewhere. It could be the scar of an operation to implant something in or near the brain. It could also be a scar left by a battle against another reptile or by running into a submerged boulder!

Blade began cutting, slowly and methodically, keeping well clear of the scar. He cut through the hide and into the skull, then began working his way around the scar. At last a circle of hide about a foot in diameter was loose. Blade gripped it by one side and thrust his sword gently in under it, to pry it free.

As he thrust, the point of his sword struck something solid. Blade poked gently and heard a sound that could only have been made by his sword striking metal or plastic. He drew his sword out, put it down, and began carefully stripping the hide off by hand.

At last a bloody circle of skull lay exposed. A little to one side of the center was a disk of translucent glass or plastic, about six inches in diameter. Several wires crisscrossed the surface. Blade could make out the faint patterns of what was unmistakably advanced microcircuitry.

There it was-complete and undeniable evidence that someone was implanting something, probably a control device, in the brains of the sea reptiles.

Who? The device itself gave no real clues. Microcircuitry obeyed certain basic laws that were the same for any people or race. All that was implied was a certain level of technology-and the existence somewhere in this Dimension of somebody with that level of technology.

That meant the Kargoi and anybody else who managed to survive the rising waters were in more danger than they could know. No matter how much Blade taught them, they could still be doomed.

Blade swore, first mentally, then out loud. He didn't feel helpless-he never did-but for once he did feel that the opposition might be a trifle overpowering!

He put the flap of hide back in place, stood up, and signaled to the others to gather around him. They came slowly, Paor leading them.

Blade laid his sword across the beast's skull and spoke loudly.

«The brains of these creatures are not fit for sacrifice. They have been attacked by an evil growth, that makes them mad.»

Paor nodded. «So that is why they were attacking us?»

«Yes «

It was not the best possible lie, but it should last until the Kargoi were ready to learn the truth-if that time ever came.

Chapter 13

With all the other men who'd worked beside him, Blade went down to the sea to scrub off the blood and filth. Then Blade rode up to where the smashed wagons lay. He began picking up boards and tying them on the back of his drend.

Paor followed him. «What are you doing, Blade?»

«I'm going to build a raft. Do you want to help me?»

«I suppose I can. Why do you want to build it?»

«I want to go out on the water farther than I can swim and see how these beasts live there.»

Paor's mouth opened and he stood speechless for a moment. «Blade, they will come and smash the raft. Then they will gulp you down in a mouthful!»

«Perhaps. But I do not know that. I do not know many things about these creatures, and I need to know them. The Kargoi need to know them too.»

«You cannot do this any other way?»

«Not without sending someone else into danger that I will not face myself. Would you have me do that?»

Paor was silent again. He could recognize a man who'd made up his mind to the point where there was no arguing with him.

With the help of half a dozen warriors, the raft quickly took shape. It was about ten feet by six feet, just able to keep Blade afloat and dry. It would never support a sail, so Blade carved one of the reptile ribs into a combination pole and paddle.

The warriors watched grim-faced from the shore as he set out, and Naula was weeping openly. No doubt his voyage seemed as mad to them as that of Columbus had to his Spanish friends. Blade was not going nearly as far-in fact, he was barely going out of their sight. But he was in just as much danger, if not more.

Blade had to push and pull the raft some distance before it would float with his weight on it. Then he scrambled aboard and began paddling steadily. Behind him the figures of the watchers on shore grew slowly but surely smaller.
