Appah Rao knew exactly who Colonel Ross truly was, and what McCandless had been looking for, and worse, Rao now knew that his own treachery was in dire danger of being discovered which meant that this was no time to look weak in front of the Tippoo. But nor was Appah Rao ready to betray McCandless. That was partly because of an old friendship, and partly because Appah Rao half suspected he might have a better future if he was allied to the British. 'We know they're short of food,' he said, 'and that man looks thin enough.'

'So you don't consider him a spy?'

'Spy or not,' Appah Rao said coldly, 'he is your enemy.'

The Tippoo shrugged at the evasive answer. His good sense suggested that the prisoner was not a spy, for why would he wear his uniform? But even if he was, that did not worry the Tippoo overmuch. He expected Seringapatam was full of spies, just as he had two score of his own men marching with the British, but most spies, in the Tippoo's experience, were useless. They passed on rumours, they inflated guesses and they muddled far more than they ever made plain.

'Kill him,' one of the Tippoo's Muslim generals suggested.

'I shall think about it,' the Tippoo said, and turned back through one of the balcony's inner archways into a gorgeous room of marble pillars and painted walls. The room was dominated by his throne, which was a canopied platform eight feet wide, five foot deep and held four feet above the tiled floor by a model of a snarling tiger that supported the platform's centre and was flanked on each side by four carved tiger legs. Two silver gilt ladders gave access to the throne's platform which was made of ebony wood on which a sheet of gold, thick as a prayer mat, had been fixed with silver nails. The edge of the platform was carved with quotations from the Koran, the Arabic letters picked out in gold, while above each of the throne's eight legs was a finial in the form of a tiger's head. The tiger heads were each the size of a pineapple, cast from solid gold and studded with rubies, emeralds and diamonds. The central tiger, whose long lean body supported the middle of the throne, was made of wood covered with gold, while its head was entirely of gold. The tiger's mouth was open, revealing teeth cut from rock crystal between which a gold tongue was hinged so that it could be moved up and down. The canopy above the golden platform was supported by a curved pole which, like the canopy itself, had been covered with sheet gold. The fringes of the canopy were made of strung pearls, and at its topmost point was a golden model of the fabulous hummah, the royal bird that rose from fire. The hummah, like the tiger finials, was studded with jewels; its back was one solid glorious emerald and its peacock-like tail a dazzle of precious stones arrayed so thickly that the underlying gold was scarcely visible.

The Tippoo did not spare the gorgeous throne a glance. He had ordered the throne made, but had then sworn an oath that he would never climb its silver steps nor sit on the cushions of its golden platform until he had at last driven the British from southern India. Only then would he take his royal place beneath the pearl-strung canopy and until that bright day the tiger throne would stay empty. The Tippoo had made his oath, and the oath meant that he would either sit on the tiger throne or else he would die, and the Tippoo's dreams had given him no presentiment of death. Instead he expected to expand Mysore's frontiers and to drive the infidel British into the sea where they belonged, for they had no business here. They had their own land, and if that far country was not good enough for them, then let them all drown.

So the British must go, and if their destruction meant an alliance with the French, then that was a small price to pay for the Tippoo's ambitions. He envisaged his empire spreading throughout southern India, then northwards into the Mahratta territories which were all ruled by weak kings or child kings or by tired kings and in their place the Tippoo would offer what his dynasty had already given to Mysore: a firm and tolerant government. The Tippoo was a Muslim, and a devout one, but he knew the surest way to lose his throne was to upset his Hindu subjects and so he took good care to show their temples reverence. He did not entirely trust the Hindu aristocracy, and he had done what he could to weaken that elite over the years, but he wished only prosperity on his other Hindu subjects for if they were prosperous then they would not care what god was worshipped in the new mosque that the Tippoo had built in the city. In time, he prayed, every person in Mysore would kneel to Allah, but until that happy day he would take care not to stir the Hindus into rebellion. He needed them. He needed them to fight for him against the infidel British. He needed them to cut down the red-coated enemy before the walls of Seringapatam.

For it was here, on his island capital, that the Tippoo expected to defeat the British and their allies from Hyderabad. Here, in front of his tiger-muzzled guns, the redcoats would be beaten down like rice under a flail. He hoped they could be lured into the slaughter-yard he was preparing on the western bastions, but even if they did not take the bait and came at the southern or eastern walls, he was still ready for them. He had thousands of cannon and thousands of rockets and thousands of men ready to fight. He would turn their infidel army into blood and he would destroy the army of Hyderabad and then he would hunt down the Nizam of Hyderabad, a fellow Muslim, and torture him to a slow and deserved death which the Tippoo would watch from his canopied golden throne.

He walked past the throne to stare at his favourite tiger. This one was a life-size model, made by a French craftsman, that showed a full-grown beast crouching above the carved figure of a British redcoat. There was a handle in the tiger's flank and when it was turned the tiger's paw mauled at the redcoat's face and reeds hidden within the tiger's body made a growling sound and a pathetic noise that imitated the cries of a man dying. A flap opened in the tiger's flank to reveal a keyboard on which an organ, concealed in the tiger's belly, could be played, but the Tippoo rarely bothered with the instrument, preferring to operate the separate bellows that made the tiger growl and the victim cry out. He turned the handle now, delighting in the thin, reedy sound of the dying man. In a few days' time, he thought, he would stun the very heavens with the genuine cries of dying redcoats.

The Tippoo finally let the tiger organ fall silent. 'I suspect the man is a spy,' he said suddenly.

'Then kill him,' Appah Rao said.

'A failed spy,' the Tippoo said. 'You say he is a Scot?' he asked Gudin.

'Indeed, Your Majesty.'

'Not English, then?'

'No, sire.'

The Tippoo shrugged at the distinction. 'Whatever his tribe, he is an old man, but is that reason to show him mercy?'

The question was directed at Colonel Gudin who, once it was translated, stiffened. 'He was captured in uniform, Your Majesty, so he does not deserve death.' Gudin would have liked to add that it would be uncivilized even to contemplate killing such a prisoner, but he knew the Tippoo hated being patronized and so he kept silent.

'He is here, is he not?' the Tippoo demanded. 'Does that not deserve death? This is not his land, these are not his people, and the bread and water he consumes are not his.'

'Kill him, Your Majesty,' Gudin warned, 'and the British will show no mercy on any prisoners they take.'

'I am full of mercy,' the Tippoo said, and mostly that was true. There was a time for being ruthless and a time for showing mercy, and maybe this Scotsman would be a useful pawn if there was a need to hold a hostage. Besides, the Tippoo's dream the night before had promised well, and this morning's auguries had been similarly hopeful, so today he could afford to show mercy. 'Put him in the cells for now,' the Tippoo said. Somewhere in the palace a French-made clock chimed the hour, reminding the Tippoo that it was time for his prayers. He dismissed his entourage, then went to the simple chamber where, facing west towards Mecca, he made his daily obeisances.
