Over three days of hard riding, Kublai ran his horse to complete exhaustion. The animal cropped grass in its sleep, but there was never enough time for it to recover before he had to mount again. He was in pain as he climbed into the saddle on the fourth day. He did not have the calluses of the scouts and great patches of skin had rubbed away on his buttocks and lower back. Each morning was an agony until the scabs broke and settled to a numb ache that would last all day. He did not know exactly how far he had come, only that the khan’s army were far behind him. Batu had kept an entire tuman of warriors and their families when he travelled to his new lands. They would have grown in number and so many could not be hidden easily. Kublai expected to find signs of them, though that was a challenge for another day.
His immediate problem was that his horse had lost weight alarmingly and was sweating and chewing yellow spit at its mouth. It was time to test the yam lines in a plan that had seemed simple back in Karakorum. From his saddlebags, Kublai drew out a set of small bells sewn into cloth. He draped them over his saddle and took his bearings once again, from the hills around him. There was no one in sight, but he had seen a yam station some twenty miles back and aligned himself to the path worn by its riders. He took stock of himself for the last time and winced at his own weariness. No yam rider rode with packs on his mount. Weight was everything. With a grimace, he wrenched the buckles open and let his supplies tumble out. His bow followed and he held his sword for a long moment before placing it on top of the small pile of leather and cloth. In hostile territory, he felt as helpless as a newborn child without it, but there was no alternative. He kept only a small leather bag he could strap to his back, exactly the sort of thing yam riders carried. He had even written an innocuous letter to a false name, ready to be shown if he were stopped and searched, though that was not likely. No one interfered with a yam rider.
On a whim, he sliced the bags into strips, then wrapped the scabbarded sword securely, making a package that he could hide. The blade was valuable and though he doubted he would ever see it again, he could not just leave it in the dust for scavengers or, worse, the khan’s scouts when they came riding behind him.
Kublai drew his horse into some trees and settled down to wait for dusk. There could only be a few miles to go and he wanted to arrive at the yam station at sunset, or even night. It had been Genghis himself who set the distance between yam stations at twenty-five miles. Some of them had been in operation for so long that wide roads stretched between them and families had built homes of brick and clay. He lay back against a tree trunk with the reins looped around his fist.
He awoke to find the trees were dark around him. He had no idea how much time had passed and cursed as he stood up and reached for his saddle. His horse whinnied, stepping away, so that he had to slap its face to get it to stand still.
In moments, he was back on the road, trotting and listening for signs of life. The moon had barely risen and he was thankful the night was still with him. It was not long before he saw lights ahead and forced his mount into a gallop once more. The bells on his saddle jingled at every step, loud in the darkness.
The yam station was a small one, built of flint and limestone in the wilderness, with little more than a few outbuildings and a cobbled yard. Torches had been lit as they heard him approach and Kublai rode in confidently, seeing two men waiting. One carried a fat waterskin and the other a platter of steaming meat scraps, still dripping water from the boil-pot inside. Another horse was already being led out of the stables, made ready as he dismounted.
‘Who are you?’ the man with the platter asked suddenly.
‘I’ve come from Karakorum, with urgent messages,’ Kublai snapped. ‘Who are you?’
‘Sorry,’ the man replied. He still looked suspicious and Kublai saw his gaze fall on the horse he had brought in. Kublai was not the first to think of stealing a yam pony in such a way, but the quality of the mounts they brought in usually gave thieves away. Kublai saw the man nod grudgingly to himself. Even so, he spoke again as Kublai took a double handful of moist lamb shreds and chewed them.
‘If you’re from Karakorum, you’ll know the yam master there.’
‘Teriden?’ Kublai said around his mouthful. ‘Big Christian with a red beard? I know him well.’
It was an easy test for a young man who’d grown up in the city, though his heart thumped in his chest at the thought of being found out. Trying to hide the stiffness of his saddle sores, he mounted the fresh horse, adjusting his small pack on his shoulders as he accepted the skin and knocked back a draught of airag mixed with water. It was cheap and sour, but it warmed him and he gasped as he tossed it back. From that point on, his only sustenance would come from yam stations.
‘I’ll tell him you keep a good house here,’ he said as he took up the reins and trotted the horse to the stone gate. The yam staff were already busy unsaddling his last horse and rubbing it down. The animal steamed in the torchlight and no one bothered to reply. Kublai smiled and dug in his heels, clattering out onto the road north. It had worked and it would work again. It had to if he were to stay ahead of the khan’s army. No message could move faster than those riders. Until he spoke to Batu himself, the man would be completely unaware of the threat against him.
As Kublai left, the yam servant stared thoughtfully after him. He’d never seen yellow eyes like those before. Genghis was said to have had such eyes. The man scratched a flea bite on his cheek, lost in thought. After a time, he shrugged and went back to work.
The four men had watched the trail for three days, hunting in pairs, so that there were always rabbits for the stew each night. There was a huge warren nearby and it was easy enough to set strangling snares over the holes. They had a good view of the road through the mountains and so they spent their time talking, or gambling with knucklebones, or just repairing old kit. They knew they could expect to be relieved in another two days and they were approaching the end of their time. There had been little excitement. Just one family of peddlers had passed through and the men were not interested in the cheap goods they had in their little cart, drawn by an ancient pony with one white eye. With rough laughter and a kick, they had sent them on their way.
‘Someone coming,’ said Parikh, the youngest of them.
The other three shuffled over to the edge of their small camp, looking down at the trail below while being careful not to show their heads. Their bows were well wrapped against damp, lying unsprung so the strings didn’t stretch. Nonetheless, each man had the weapons in easy reach. They could have an arrow ready to fly in moments. They peered down, cursing the morning haze that blurred the air, seeming to come from the rocks themselves before it burned off.
Despite the mist, they could see a single man walking slowly, leading a lame horse. His head was bowed and he looked like any poor warrior, stumbling home after many nights hunting, or searching for a lost animal. Even so, the watchers had been placed on that road as the first line of defence and they were wary of anyone. The oldest, Tarrial, had seen more than his share of ambushes and battles. He alone had scars on his forearms and they looked to him for decisions. Sound carried far in the mountains, and with a silent gesture Tarrial sent Parikh off on his own along the ridge. The lad would scout for anyone else creeping up on them, as well as providing a second shot from hiding if something went wrong. The others waited until Parikh reached a place where he could see half a mile along the back trail. The young man raised a flat palm to them, visible at a distance. Clear.
Tarrial relaxed.
‘Just one man. Stay here and don’t steal my food. I’ll go down to him.’
He made no attempt to hide his progress as he scrambled down the rocky scree. In fact, he made as much noise as possible, rather than make the stranger nervous. Years before, Tarrial had seen his jagun officer killed on patrol in Samarkand. The officer had kept to the shadows while thieves robbed a store. As one of them passed him, he had stepped out and laid a heavy hand on his shoulder, hoping to scare the thief half to death. His ploy had worked, but the man jammed a dagger into his ribs in panicked reflex. Tarrial smiled fondly at the memory of the officer’s face.
By the time he reached
