As the hours of night drew on and the fortress fell silent around them, Babur looked on as the old lady wrote and wrote, pausing only to sharpen her quill and to call for more ink. It was extraordinary, he thought, how much she knew of the blood rivalries and bitter enmities but also the complex marriage links and deep personal loyalties between the clans that went back almost to the days of Genghis Khan. For the first time he felt grateful to her for all the hours she had forced him to spend learning who among the tribal chiefs were friends, who were foes and — most important of all — why. Watching the thin set line of her mouth, he was glad that she was his ally, not his enemy.

As every note was written — the Turki script sprawling over the paper — it was folded, sealed with red wax and handed to Wazir Khan to be entrusted to one of his men. Outside, the courtyard echoed to the sound of departing hoofbeats. Only when the call to prayer rose through the early-morning mist did Esan Dawlat finally lay down her pen.

Chapter 2

First Blood

Babur watched from his horse as the green-grey jade sarcophagus containing his father’s body was borne into the tomb by eight of Wazir Khan’s guards. Thick sheepskins on their shoulders cushioned them against the hardness of the stone but the coffin was a mighty weight. Sweat poured down their wind-tanned faces and one man stumbled, almost losing his hold. There was a gasp from the assembled onlookers — it would be a dreadful portent if the sarcophagus should fall to the earth. Babur’s stomach tightened and he glanced at the vizier a few feet away, but Qambar-Ali’s tortoise face was impassive.

‘Careful, man, you carry our king.’ At the bite in Wazir Khan’s voice, the guard steadied himself, rebracing his shoulder to the burden, and the pall-bearers shuffled slowly into the passageway sloping down to the burial chamber in the heart of the tomb.
