Tim Severin - Sworn Brother

As the exchange of insults continued, I felt shooting pains in my head. Grettir did not seem affected. Perhaps he was distracted by his anger at Ongul. But I began to feel feverish. The day which had begun with such promise was turning heavy with menace. The sky was clouding over. I felt unsteady and sat down on the ground to stop myself retching. The shouting match between the two men echoed off the cliffs, but then I heard something else: a growing clatter of wings and a swelling volume of bird calls, rising in pitch. I looked back towards the north. Huge numbers of seabirds were taking to the sky. They were launching themselves in droves from the cliff ledges, gliding down towards the sea and then flapping briskly to gain height as they began to group together. They reminded me of bees about to swarm. The main flock spiralled upward as more and more birds joined in, flying up to meet their companions. Soon the flock was so immense it had to divide into ranks and squadrons. There were thousands upon thousands of them, too many to count or even guess their numbers. Many birds still stayed on the ledges, but most were on the move. Section by section, breed by breed, the great mass of flying creatures circled higher and higher like a storm cloud, until smaller groups began to break away and head out towards the sea. At first it seemed that their departure was random, in all directions. But then I realised there was one direction which all the birds avoided: none of them was returning to Drang. The birds were abandoning the island.

I dragged myself upright and walked unsteadily to where Grettir stood. My head and muscles ached. I felt terrible. 'The birds,' I said, 'they're leaving.'

'Of course they are,' he answered crossly over his shoulder, 'they leave every year about this time. It is the end of their breeding season. They go now, and come back in the spring.'

He searched around in the grass until he found a rounded stone, about the size of a loaf. Plucking it from the grass, he heaved it above his head with both hands and let fly, aiming at Ongul in the boat far below. Ongul had imagined he was safely out of range. But he had not reckoned with Grettir the Strong who, since boyhood, had amazed everyone with just how far he could pitch a rock. The stone flew far out, its arc greater than I had imagined possible. Grettir's aim was true. The stone plummeted down, straight at the little skiff. It missed Ongul by inches. He was standing amidships, working the oars. The stone landed with a thump on a bundle of black rags on the stern thwart. As the stone struck, I saw the bundle shiver and flinch, and over the crying of the myriad departing birds, I heard distinctly a hideous cry of pain. At that moment I remembered where I had felt that same chill, the same sense of evil, and heard the same vile cry. It was when Thrand and I had fought the Danes in the sea ambush and I had had a vision of Thorgerd Holgabrud, the blood drinker and witch.

As Ongul rowed away, I was swaying on my feet.

'You've got a bad attack of some sort of fever,' said Grettir and put his arm around me to stop me falling. 'Here, Illugi, give me a hand to carry Thorgils inside.' The two of them lifted me down into the dugout and made me comfortable on some sheepskins on the earth floor.

I had just enough strength to ask, 'Who was in the boat with Ongul? Why didn't they show themselves?'

Grettir frowned. 'I don't know,' he said, 'but whoever it was is nursing a very bad bruise or a broken bone and won't forget this day in a hurry.'

Perhaps the birds began their migration because they knew that the weather was about to change, or perhaps - and this was my own private explanation — they were disturbed from their roosts by the evil that visited us that day. At any rate that was the last day of summer we enjoyed. By evening the rain had set in and the temperature began to fall. We did not see the sun again for a fortnight, and by then the first of the autumn gales had mauled the island unseasonably early. The ledges on the cliffs were empty of all but a handful of seabirds, and Drang had settled back prematurely into its gloomy routine though the autumn equinox had barely passed.

I continued very ill and weak with fever and from my sick bed I could see that Grettir was more subdued than usual. There was despondency in his face, perhaps at the thought of another winter spent in the raw, cramped isolation of Drang. He took to leaving the dugout at first light and often did not reappear until dusk. Illugi told me that his brother was spending much of his time alone, sitting staring out towards the mainland, saying nothing, refusing to be drawn into conversation. At other times Grettir would descend the ladders and, when the low tide permitted, walk around the island, furiously splashing through the shallows, always by himself. It was from one of these excursions that he returned with that look I had never seen before: a look of dismay.

'What's worrying you?' I asked.

'Down on the beach, I had that same feeling we both sensed the day that Ongul came to visit us and I threw the stone. I felt it mildly at first, but as I walked around the island it came on me more strongly. Oddly, I also had a stroke of luck. On the far side of the island I came across a fine piece of driftwood. The current must have brought it there from the east side of the fiord. It was a good, thick log, an entire tree trunk, roots and all, ideal for firewood. I was bending down to drag it further up the beach when I felt ill — I thought I was going down with your fever. But then it occurred to me that my feeling might have something to do with that particular spot on the beach - it faces across to that ruffian Ongul's farm - or perhaps it was to do with the log. I don't know. Anyhow, I took the wave of nausea to be a warning. So instead of salvaging the log, I shoved it out to sea again. I didn't want to have anything further to do with it.'

The very next day Glaum appeared with a smug expression at the door of the dugout. 'I've done well,' he said. 'Better than the lot of you, though you treat me as if I'm useless.'

'What is it, Glaum?' asked Grettir sourly.

We had all become weary of Glaum's endless vulgarities — his favourite amusement was to let out controlled farts, which did not help the fug of the dugout, and he snored so much that, unless the night was wild, we made him sleep outside. He had made a noxious lair for himself in the hollow by the ladders where I had first stumbled across him. There he pretended to play sentry, though there was little likelihood of any surprise attack now that the weather was so bad.

'I've salvaged a fine log,' said Glaum. 'Took me enough trouble too. Found it on the beach by the foot of the ladders and I've managed to hoist it up with ropes. There's enough timber to burn for three or four nights at least.'

It was one of those days when there was a brief break in the dreary weather and Grettir had half-carried me out of the fetid dugout so I could sit in the open air and enjoy the watery sunshine.

Glaum went on, 'Better cut up the log now. Before it rains again.'

Grettir picked up our axe. It was a fine, heavy tool, the only axe we had, too important for our well-being to let Glaum handle in case he lost it or damaged the blade. Grettir walked to where Glaum had dragged the log. I was lying on the ground so I could not see the log itself because it was concealed in the grass. But I heard Grettir say, 'That's strange, it's the same log I threw back into the water the other day. The current must have carried it right around the island and brought it back in the opposite beach.'

'Well, it's a good log wherever it came from. Well seasoned and tough,' said Glaum, 'and it took me enough trouble to get it up here. So this time it's not going to waste.'

I saw Grettir raise the axe with both hands and take a hefty swing. A moment later I heard the sound of a blow that has been mis-aimed - the false echo - as Grettir fell.
