'Arkoun!' Tanus bellowed. 'I have been looking for you.'
Arkoun could not understand the words, but the sense of them was unmistakable. He laughed into the wind, and his beard blew out like smoke around his goaty face.
'I know you!' He swung the silver-blue blade around his head, and it hissed and whined in the air. 'This time I will kill you.' He started forward, out along the narrow arch of stone, running with long, lithe strides straight at Tanus.
Tanus altered his grip on the handle of his bronze shield, and tucked his head in behind it. He now knew the power in that glittering blade, and I saw that he did not intend meeting it with his own softer bronze. Arkoun had also learned discretion from their last brief encounter. From the way he carried the blue sword, I guessed that he would not attempt another rash overhand stroke.
As they came together, Arkoun gathered himself. I saw his shoulders brace and his weight swing forward. He used the impetus of his charge to send the straight thrust at Tanus' head. Tanus lifted the shield and caught the blue blade in the centre of the heavy bronze target. It would have snapped a sword of inferior metal, but the blue sword sheared through it as if it were goat-skin. Half its silver length was buried in the yellow bronze.
Then I realized Tanus' intention. He twisted the shield at an angle so that the blade was trapped. Arkoun struggled to withdraw his weapon, he wrestled and heaved, throwing his full weight backwards, but Tanus had the blue sword in a vice of bronze.
Arkoun gathered all his strength and pulled back again. This time Tanus did not resist him. He leaped forward in the direction that Arkoun was heaving, and this unexpected move threw Arkoun off-balance.
Arkoun staggered away, tripped and teetered on the brink of the chasm. In order to keep his balance, he was forced to relinquish his grip on the hilt of the blue sword, and to leave it still embedded in the shield.
He windmilled his arms as he swayed out over the drop. Then Tanus shifted his ground, put his shoulder behind the shield and barged forward. The shield crashed into Arkoun's chest, and the pommel of the blue sword caught him in the pit of his belly with all Tanus' weight and strength behind it.
Arkoun was thrown backwards, out into empty space. He turned a slow somersault in the air and then went straight down, with his robe ballooning around him, and his beard streaming like a chariot pennant in the wind of his fall.
From where I stood, I watched him make the same last journey on which he had sent so many other unfortunate souls. From the causeway until he struck the rocks a thousand feet below, he screamed all the way down, on a high, receding note that was cut off abruptly at the end.
Tanus stood alone in the middle of the causeway. He still held the shield on high with the sword buried in the metal.
Slowly the tumult and the fighting died away. The Ethiopians had seen their king vanquished and cast down. The heart went out of them. They threw down their weapons and grovelled for mercy. The Egyptian officers were able to save some of them from the blood-crazed Shilluk, and these were dragged away to where the slave-masters waited to bind them.
I had no eyes for any of this, for I was watching Tanus out there on the bridge. He began to walk towards the gateway, of the fortress, and the men cheered him and raised their weapons in salute.
'There is plenty of fight in the old bull yet,' Memnon laughed in admiration, but I did not laugh with him. I felt the chill premonition of some awful tragedy, like the air stirred by the beat of vultures' wings as they settle to their gruesome feast.
'Tanus,' I whispered. He walked with a slow and hampered gait. He lowered the shield as he came down the bridge of stone, and only then did I see the stain spreading on his breastplate.
I thrust Masara into Memnon's arms and ran down the outer staircase. The Ethiopian guards at the gate tried to surrender their weapons to me, but I pushed my way past them and ran out on to the causeway.
Tanus saw me running towards him and he smiled at me, but the smile was lop-sided. He stopped walking and slowly his legs buckled beneath him, and he sat down heavily in the middle of the bridge. I dropped on my knees beside him, and saw the rent in the crocodile-skin of his breastplate. Blood oozed from it, and I knew that the blue sword had bitten deeper than I had believed possible. Arkoun had driven the point through the bronze shield, on through the tough leather breastplate, and into Tanus' chest.
Carefully I untied the straps that held his armour, and lifted away the breastplate. Tanus and I both looked down at the wound. It was a penetrating slit the exact width of the blade, like a tiny mouth with wet red lips. Every breath that Tanus drew frothed through that horrid opening in a rash of pink bubbles. It was a lung wound, but I could not bring myself to say it. No man can survive a sword-cut through one of his lungs.
'You are wounded.' It was an asinine remark, and I could not look at his face as I said it.
'No, old friend, I am not wounded,' he replied softly. 'I am killed.'
TANUS' SHILLUK MADE A LITTER WITH their spears, and covered it with a rug of sheepskin. They lifted him and carried him, gently and slowly, into the fortress of Adbar Seged.
We laid him on the bed of King Arkoun, and then I sent them all away. When they were gone, I placed the blue sword upon the bed beside him. He smiled and laid his hand on the gold and jewelled hilt. 'I have paid a high price for this treasure,' he murmured. 'I would have liked to wield it just once upon the battlefield.'
I could offer him no hope or comfort. He was an old soldier, and he had seen too many lung wounds. I could not hope to deceive him as to the final outcome. I bound up the wound with a pad of wool and a linen bandage. While I worked, I recited the incantation to quell the bleeding, 'Retreat from me, creature of Seth?'
But he was sinking away from me. Each breath he drew was an effort, and I could hear the blood stirring in his lungs like a hidden creature in the deep swamps.
I mixed a draught of the sleeping-flower, but he would not drink it. 'I will live every minute of my life,' he told me. 'Even the very last one.'
'What else is there that I can do for you?'
'You have done so much already,' he said. 'But there is no end to the demands that we all make upon you.' ' I shook my head, 'There is no end to what I would give.'
'These last things then I ask of you. Firstly, you will never tell Mernnon that I am his sire. He must always believe that the blood of the pharaohs runs in his veins. He will need every strength to meet the destiny that awaits him.'
'He would be as proud to share your blood as that of any king.'
'Swear to me you will not tell him.'
'I swear it,' I replied, and he lay a while gathering his strength.
'There is one other boon.'
'I grant it before you name it,' I said.
'Take care of my woman who was never my wife. Shield and succour her as you have done all these years past.'
'You know I will.'
'Yes, I know you will, for you have always loved her as much as I have. Take care of Lostris and of our children. I give them all into your hands.'
He closed his eyes, and I thought that the end was close, but his strength surpassed that of other men. After a while he opened them again.
'I wish to see the prince,' he said.
'He waits for you on the terrace,' I answered, and went to the curtained doorway.
Memnon stood at the far end of the terrace. Masara was with him, and the two of them stood close together but not touching. Their expressions were grave and their voices muted. They both looked up as I called.
