Suspicious, Kalam slowly nodded. ‘Yet I have seen so many more, so many new symbols. What of them?’

‘Amidst the cloud of locusts there is but one,’ Mebra said. ‘How best to keep the Red Blades blind? Please, Kalam, you must go. I have repaid the debt.. .’

‘If you have betrayed me, Adaephon Ben Delat shall know of it. Tell me, could you escape Quick Ben with his warrens unveiled?’

Mute, his face pale as the moonlight, Mebra shook his head.

‘The whirlwind.’

‘Yes, I swear by the Seven.’

‘Do not move,’ Kalam commanded. One hand on the long-knife at his belt, the assassin stepped forward, crouched and collected the object that Mebra had dropped earlier. He heard the spy’s breath catch and smiled. ‘Perhaps I will take this with me, as guarantee.’

‘Please, Kalam—’

‘Silence.’ The assassin found himself holding a muslin-wrapped book. He pulled the dirt-stained cloth away. ‘Hood’s breath!’ he whispered. ‘From the High Fist’s vaults at Aren ... into the hands of an Ehrlii spy.’ He looked up and met Mebra’s eyes. ‘Does Pormqual know of the theft of that which is to unleash the Apocalypse?’

The little man grinned, displaying a row of sharp silver-capped teeth. ‘The fool could have his silk pillow stolen from under him and would not know it. You see, Kalam, if you take this as guarantee, every warrior of the Apocalypse will be hunting you. The Holy Book of Dryjhna has been freed and must return to Raraku, where the Seeress—’

‘Will raise the Whirlwind,’ Kalam finished. The ancient tome felt heavy as a slab of granite in his hands. Its bhederin-hide binding was stained and scarred, the lambskin pages within smelling of lanolin and bloodberry ink. And on those pages ... words of madness, and in the Holy Desert waits Sha’ik, the Seeress, the rebellion’s promised leader . . .’You shall tell me the final secret, Mebra, the one the carrier of this Book must know.’

The spy’s eyes widened with alarm. ‘This cannot be your hostage, Kalam! Take me in its stead, I beg you!’

‘I shall deliver it into the Holy Desert Raraku,’ Kalam said. ‘Into Sha’ik’s own hands, and this shall purchase my passage, Mebra. And should I detect any treachery, should I see any single soldier of the Apocalypse on my trail, the Book is destroyed. Do you understand me?’

Mebra blinked sweat from his eyes, then jerked a nod. ‘You must ride a stallion the colour of sand, your bloods blended. You must wear a telaba of red. Each night you must face your trail, on your knees, and unwrap the Book and call upon Dryjhna – that, and no more, not another word, for the Whirlwind goddess shall hear and obey – and all signs of your trail shall be obliterated. You must wait an hour in silence, then wrap the Book once again. It must never be exposed to sunlight, for the time of the Book’s awakening belongs to Sha’ik. I shall now repeat those instructions—’
