I am too late, thought Ailsa. They are dead. But still it did not cross her mind to leave them to drift down into the cold and dark below, and the things of cold and dark that waited for them there.
Carn was fidgety, but Ailsa murmured to steady him while she made her arrangements. She slid the sword into the scabbard to get it out of the way, unclipped the lead rope and ran it through the shoulder strap of the man’s swordbelt, and then clipped it to the load hook so that Carn could take the weight. Now with both hands free she found the buckles on the man’s armour and undid them. The thigh-pieces came loose and fell, but the body armour was held fast by the sword belt. She tied the loose end of the lead rope round the woman’s chest, beneath the arms, and, supporting the man’s weight in the crook of her elbow, managed to undo the buckle. The body armour was hinged at the shoulders, like a clam shell, with a hole for the man’s neck. She eased the contraption over his head and let it fall. Below it she found that he too was wearing a covering, a soft brown stuff like cured sharkskin. She refastened his swordbelt round him, and retied the lead rope round his chest so that the two bodies, almost weightless now without the armour, floated side by side from the load hook. Finally she adjusted the harness as best she could to balance her own body against the trailing load, and clipped herself in. Before she flicked her tail to set Carn going, she cast a look down into the black deeps beneath her.
They were nearer than they had been. The limit itself was moving. She knew it, though she could feel no change in the water around her. The underdeeps—that whole immense mass of cold and dark—were rising towards her. Terror, nightmare, swept through her as before. Carn bolted.
He surged for the surface, for the warm and golden water beneath the wave roots. Once there, he levelled and surged on, still in a crazed panic beyond Ailsa’s control. His madness had the effect of blocking her own, by giving her something urgent to do. At first she tried to master him, to force his head round, to pierce through his panic with shouted commands. She reached and gripped the bit-ring and heaved with all her strength. She had heard her father’s huntmaster, Desmar, describe having done this with a bolting blue-fin, but Carn was too strong for her.
Then she realised that at least he was bolting for home. Her best hope was to let him have his way. But swimming at full surge all that distance, with the inert load of the airfolk trailing behind, he could injure himself beyond recovery. Last year a group of young nobles racing for wagers on half-trained stock had brought them home in such a state that her father, furious, had banished the riders to remote reefs. Two of the fish had had to be put down. She would not let that happen to Carn.
It still did not cross Ailsa’s mind to abandon the airfolk. She was sure that, having done what she had, she must now go through with it, and face whatever punishments she must. There was something about the woman, not only the covering and jewels that she wore, but the way that she had stood and moved, had held herself in the face of death, that spoke to Ailsa. She too was a king’s daughter.
With one hand she clasped the grip and with the other unclipped her harness and free-rode. Now she had to transfer herself across Carn’s body, round behind the big forefin. This was riding-school stuff, to be done at a steady pulse. She’d never tried it at full surge in the open sea. She shifted her left hand down to the centre-belt, which circled Carn’s body just in front of the forefin, let go of the grip and trailed at arm’s length. Now she changed hands on the belt and with her left arm reached round behind the fin and felt and found the belt again at the limit of her stretch. Arching her body so that the rush of water lifted her clear of Carn’s, she let a twist of her tail flip her across the spiny ridge that ran from forefin to afterfin, and she was there. She rested a moment, transferred her right hand to grip the load hook, and then with a straining effort used her left to haul on the doubled lead rope until she had enough slack to thumb the loop off the hook and let go. As soon as he was free of the dragging load, Carn surged away, out of sight.
After that it was a matter of working out the easiest way for her to tow the two bodies. She finished with the rope running over the back of her neck and the airfolk trailing, one on each side, leaving her arms free to balance the load against the thrust of her tail. When the rope began to chafe her neck, she stopped and unfastened the top half of the man’s covering. To her surprise he was wearing yet another layer of covering, a fine white stuff with delicate patterns at wrist and neck. She used the top covering to pad the rope where it chafed, and swam on.
As she toiled along, she brooded on the uncomfortable certainty that she must now face her father and explain not only that morning’s delinquency—she had known what she would say about that before she set out—but her dealings with the airfolk. By custom so strong that it was almost law, merfolk had nothing to do with airfolk. All tales of such meetings ended in grief. Why should this be any different? It was some while before she became aware of a quite different kind of unease, coming not from inside her but from somewhere outside. Somewhere below.
At first she told herself that it was a sort of aftershock, a leftover bit of the panic that had gripped her in the cold and dark below the limit. She tried to drive it away by returning to the problem of what she could say to her father. She was still quite sure that she had been right to do what she’d done, but how could she put her reasons into words? They were all to do with the moment at which the man and the woman had stood on the rail of the ship and by the force of their love for each other had made that moment into a lifetime. How could she make anyone else see that? To do so, they would need to see the moment.
Something tapped at her mind. The unease—the certainty of it made it more than unease—flooded back. She stared downwards, but saw nothing, felt nothing. She did not need to. Here too, she could tell, the limit had risen.
Again on the edge of panic, she forced herself to swim steadily on, but as she did so, she began more and more to feel that an immense slow wave of cold and darkness was following her across the ocean floor. If she changed course, so would the wave. Indeed, she felt it was deliberately telling her so. Just as it had tapped at her mind while she was remembering the lovers’ last moment of life, so now it was letting her know that it would follow her until she released them and let them sink through the dwindling light to where the cold and the dark waited for them.
She longed to rest but did not dare, knowing that the effort of swimming with the dragging load was all that was keeping panic at bay. By noon it was clear that she would not be home by nightfall. And then, well into the afternoon, she heard conch-calls, the thin, wavering wails that the huntsmen blew, keeping in touch along the line as they drove the game towards the waiting spear party. Like whalesong, the notes travelled far underwater. She heard one away to her left, and another nearer, another to her right, and a fourth yet further off, too widely spaced for a game drive. And no hunt was planned for today . . . but of course it was for her they were hunting. Carn had come home, spent and still in harness . . . someone must have seen the direction. . . . She headed for the nearest conch.
It turned out to be Scyto, a dour-seeming but kindly old merman who had helped break and train Carn. The moment he saw her, he blew a short call and drove his blue-fin towards her.
“My lady!” he said. “Where have you . . . what are these?”
Before she could speak, he blew the call again.
“Did Carn come home?” she said. “Is he all right?”
“He came, and maybe he’ll do. But these?”
