‘It’s done,’ Jochi murmured. He looked up at his father’s general with a bitter twist to his mouth. ‘I’ll just have to kill that great cat now, won’t I?’

Jelme smiled tightly. Outside, the noise of the crowd had grown in volume and now he could hear Jochi’s name being chanted. It would be a glorious moment, but Jelme knew the boy could not survive it. As the circle was being constructed and the cage lifted down from the cart, he had studied the animal and seen the smooth power of its muscles. Faster than a man and four times as heavy, it would be impossible to stop. He was silent with foreboding as Jochi came to his feet and flexed his shoulders. The khan’s first son had inherited his father’s blinding speed, but it would not be enough. The general saw sweat dripping down Jochi’s face in a fat bead. Genghis had not allowed him room to interpret his orders, but he still struggled against ingrained obedience. Jelme had brought the tiger to the khan. He could not simply send a boy to his death. When he spoke at last, his voice was barely a murmur.

‘I will be on the walls with a good bow. If you fall, try to hang on and I’ll kill it.’ He saw a flicker of hope in the young man’s eyes at that. Jelme recalled the only hunt he had seen in Koryo, when a tiger had taken a shaft in the heart and still disembowelled an experienced net man.

‘You cannot show fear,’ Jelme said softly. ‘No matter what happens. If you are to die tonight, die well. For your father’s honour.’

In response, Jochi turned a furious gaze on the general.

‘If he depends on me for his honour, he is weaker than I realised,’ Jochi snapped.

‘Nevertheless, all men die,’ Jelme went on, ignoring the outburst. ‘It could be tonight, next year or in forty years, when you are toothless and weak. All you can do is choose how you stand when it comes.’

For an instant, Jochi’s face cracked into a smile.

‘You are not building my confidence, general. I would value those forty years.’

Jelme shrugged, touched at the way Jochi showed courage.

‘Then I should say this: kill it and your brother will kneel to you in front of the tribes. Your name will be known and, when you wear its skin, all men will look on you with awe. Is that better?’

‘Yes, it is,’ Jochi replied. ‘If I am killed, be ready with your bow. I do not want to be eaten.’ With a deep breath, he showed his teeth for an instant, then ducked under the low doorway and out into the night. His people roared to see him, the sound filling the plains and drowning the growls of the waiting tiger.

The crowd parted to let him through and Jochi did not see their staring, cheering faces as he approached the walls of the ring. The light from torches fluttered and spat as he climbed lithely to the top, then leapt to the grass below. The tiger watched him with a terrifying focus and he did not want to open the cage. Jochi looked up at the faces of his people. His mother was the only woman he could see and he could barely meet her eyes in case it unmanned him. As his gaze drifted over her, he saw Borte’s hands twitch on the wood, as if she wanted to reach out to her first-born son.

His father’s face was set and unreadable, but his uncle Kachiun nodded to him as their eyes met. Tsubodai wore the cold face and, in doing so, hid the pain Jochi knew he would be feeling. The general could do nothing to thwart the khan’s will, but Jochi knew he at least would not relish the fight. On instinct, Jochi bowed his head to the general and Tsubodai returned the gesture. The tiger roared and opened his great mouth to gnaw at a bar in frustration, angered by the ring of baying men. The animal was a young male, Jochi saw, unscarred and inexperienced. He felt his hands shake and the familiar dry mouth before battle. His bladder made itself felt and he took a strong grip on the wolf’s-head sword of his father. It was a fine blade and he had wanted it for a long time. He had not known his grandfather Yesugei and only hoped the old man’s spirit would give him strength. He stood tall and another deep breath brought calm.

Chagatai watched him with eyes that shone in the torchlight. Jochi held his gaze for a time, showing the boy his contempt before he turned to the cage. The noise of the warriors swelled as he approached the bars and raised his hand to the iron pin that held the door shut. The tiger seemed to sense his intention and stood waiting. Their eyes met and Jochi murmured a greeting to the big cat.

‘You are strong and fast,’ he said under his breath, ‘and so am I. If I kill you, I will carry your skin in pride to the end of my days.’ He yanked on the pin and threw back the cage door, moving quickly away. The crowd fell silent, every warrior staring at the striped shape that came sliding out like oil.

Jochi backed for six long strides and stood with his sword held forwards and down, ready to lunge. His heart hammered in his chest and he felt heavy-footed and clumsy in comparison with this beast he had come to kill.

At first, the tiger ignored him. It padded around the walls, looking for a way out. Its tail twitched in irritation and discomfort as the crowd resumed their roaring. Jochi looked on as the animal stretched to its full length against a wall, its clawed feet digging furrows in the hard wood. In the cage, its strength and grace had been less obvious. Moving, it was simply deadly and Jochi swallowed nervously, waiting to be attacked.

It was aware of him. He saw its golden eyes pass over his and then fasten as it sank into a crouch, its head up. Its tail lashed on the grass and once more the crowd fell silent.

Jochi offered up his soul to the sky father. No man could stand against such a monster, he was certain. The shaking in his hands died away and he stood waiting.

The tiger attacked. When it came, it was with such an explosion of speed that Jochi was almost caught motionless. In three steps, it went from a statue to a blur and leapt straight at him.

Jochi did not try to use the sword. He threw himself to one side and was still too slow. The shoulder of the beast caught him and sent him rolling on the grass, desperate to regain his feet. He caught a glimpse of the animal landing and turning at impossible speed before it was on him once more. A jaw larger than his head clamped on his armoured left arm and he cried out in pain and shock as the pressure came on. He brought his right arm forward, thrusting the blade into the tawny chest as he went over backwards. They rolled together and the crowd went berserk, bellowing encouragement to the brave man fighting below.

Jochi felt pummelling blows as the cat’s rear paws raked him. His armour protected his belly, though the iron scales went flying as they caught in claws as long as his fingers. He felt the bones in his arm grind and the lower limbs of the tiger kept up their strikes, thumping and battering him on the grass. The animal’s breath was hot on his face as he shoved his sword in again and again, stronger in his terror than he had ever been. He could not rise with its weight on him and when the tiger tried to release his arm to bite again, he jammed the armoured sleeve deeper into its throat despite the pain.

The tiger coughed around the obstruction, wrenching its head from side to side to free its teeth. Jochi hung on as tendons tore, tears of agony filling his eyes. Had he hurt it? He did not know. The steel blade stabbed and stabbed, lost in the thick fur. He felt new pain in his legs as the beast clawed his armour to tatters. His sword was knocked from his hand and he drew a knife, plunging it into the matted neck as his left arm gave way.

Jochi screamed as stinking blood fountained over his face, blinding him. He could see nothing and the watching warriors were far away, their voices like the whispering of leaves. He felt death coming in a great wind, but he still worked the knife in deeper, sawing back and forth.
