‘You must return to the palace at once, Majesty.’

Babur was still staring at the arrow. ‘Look,’ he stooped and wrenched it from the earth, ‘there’s something round the shaft.’ He ripped off the coarse red thread that was securing a sliver of parchment and stared at the writing on it. The language was his own tongue of Turki, but the words leaped and danced before his eyes and for a moment he struggled to take in their meaning.

Wazir Khan took the paper from him and read the message aloud: ‘“The mighty Shaibani Khan, lord of the world, presents his compliments. He wishes it to be known that before three full moons have come and gone he will take possession of the shit-hole that calls itself Ferghana and piss on its throne.” ’

‘Bastard of an Uzbek,’ the soldier said contemptuously, but Babur saw anxiety in his face.

‘What is it?’ The court astrologer came hurrying over and twitched the paper from Wazir Khan’s fingers. Baqi Beg glanced at its contents and Babur heard his sharp intake of breath. The little man began to rock back and forth on the balls of his feet, hands clenched, his reedy voice rising in a wail: ‘Shaibani Khan is coming, that alachi, that killer. . I see it. . He rides a black horse that smashes men’s skulls to dust beneath its hoofs.’ His wail turned to a shriek: ‘Shaibani Khan is coming! Death and disaster ride behind him!’

Qambar-Ali, too, appeared by Babur’s side, the treasurer and the comptroller close behind. All three were shaking their heads. ‘The royal council must meet tonight after the funeral feast. Shaibani Khan does not make idle threats,’ the vizier said. Yusuf and Baba Qashqa nodded vigorous assent. So, too, did Baqi Beg.

Wazir Khan made no such gesture of agreement. Instead he was staring at the vizier in a way that Qambar-Ali did not seem to relish. ‘Vizier, perhaps you would do well to use your undoubted authority to calm the people. My guards are at your disposal should you require them to restore order.’
