'I don't feel inclined to wait for Ulla Safar's minions to sort out their mess before coming to our assistance. We'll get up to the walkway.' He pointed. 'Then we can follow the rampart round to the other side of the fortress and signal the Rainbow Moth ourselves.'

I should have suspected a scorpion under the bed, shouldn't I, when Ulla Safar put us so far away, quite out of sight of our galley. How could I have missed some hint of this in all the auguries I took before we sailed?

As Kheda thought this, a streak of light high above caught his eye. A shooting star or firedrake seared its brief path across the night sky. He stared, open-mouthed.

That's out of season, or at least early, with the rains not yet come.

'What have we got for a rope?' Dyal was already catching up lengths of discarded cloth trailing from the I garden's battered perfume trees.

Gal darted back down the steps and vanished into the smoke-filled audience room, appearing moments later with arms full of silken coverlets, face congested with the effort of not breathing. 'Who's got a knife?' he gasped.

It turned out some instinct had prompted every man to catch up his dagger. Kheda drew his own and sliced the fine weave with as much relish as if it had been Ulla Safar's throat 'How do you suggest we get the first man up to the parapet?'

Dyal was already plaiting strips into a sturdy cable. 'Leave that to us, my lord.'

When the silken rope looked barely long enough to Kheda, three of the erstwhile porters formed a practised ladder against the battlement wall and Dyal climbed deftly up their backs and shoulders. Once aloft, he threw a loop around a sturdy merlon and dropped the rope to Gal waiting eagerly below.

'You two stay here, back up Birut and Jevin,' Kheda said to the other porters. He climbed up after Gal, Telouet's sword awkwardly thrust through his belt. As he reached the parapet, the first concerned shouts from Ulla servants sounded in the garden below. 'Daish Kheda! Great lord!'

'Ignore them.' As he ran along the wall walk, Dyal ahead and Gal bringing up the rear, he heard Janne's furious censure intercepting whoever had so conveniently managed to make a way through to the garden as soon as it seemed Daish Kheda was escaping the trap.

The watchtower barred their way, the only route to the parapet beyond, the inward-looking window unaccountably shuttered. Dyal hammered wrathfully on the door. 'Open to Daish Kheda! Are you deaf as well as blind?'

Kheda heard muffled movement inside hastily stilled. He stepped forward and bent close to the crack of the door, speaking with cold precision. 'I am Daish Kheda. Open to me now or I'll demand your heads for your insolence.'

The bolts were immediately withdrawn and the door opened to reveal two youths barely old enough to shave, never mind serve in a warlord's personal guard. Neither spoke, terror plain in their white-rimmed eyes.

'Treacherous scum.' Dyal stepped forward, sword half unsheathed.

The doorway beyond stood open and Kheda saw a figure running along the wall walk. 'They're not worth the waste of our time.' He shoved Dyal towards the far door. They ran on, all three with swords now drawn, bare blades shining like parings from the Lesser Moon bright above. Lights began showing all along the citadel's upper levels. Kheda ignored them.

Young lads on watch and barely trained. Ulla Safar would be distraught as he excused himself to Ritsem Caid and Redigal Conn, bemoaning his guard captains folly in trusting to youths who had concentrated all their energies on looking outwards, rather than into the fortress. Of course, with the tales of magical foes coming up from the south, that was to be expected, if not excused. The boys would naturally be sentenced to impaling, the captain to a flogging to leave him scarred for life. But I would still be dead, along with my most influential wife, the inconvenient Itrac Chazen and as many as possible of our retinue who might be able to shed some light on these dark dealings.

The next watchtower was empty, doors wide open. The one beyond was barred. Dyal raised his sword hilt to hammer on the stubborn wood. Before his blow landed, the door opened and an armoured Ulla warrior rushed out. He charged into Dyal, knocking him off balance, the Daish man's blade scraping ineffectually over his mailed shoulder. Falling, Dyal grabbed at his assailant, wrapping his arms around his neck, tangling his legs with his own. The pair fell from the parapet, landing with a sickening crunch of bone and an agonised scream in the stone-paved courtyard below.

Kheda's sword met the shining blade thrust forward by the next man out of the watchtower, anonymous as the first behind face guard and the fine chain veil of his helmet. The warlord backed away, parrying a second stroke sweeping in at waist height. There was no way he could attack, not bare-chested against an armoured man.

'Let me past, my lord!' Gal pressed close behind him.

'There's no room.' Kheda twisted his wrist to foil another lethal thrust at his belly.

'My lord!' Alarm sharpening Gal's voice alerted Kheda to running feet at their rear.

'Sheathe your swords!'

When he heard Ulla Orhan's voice behind him, Kheda's surprise nearly gave his opponent an easy kill.

'Put up your blades.' The youth's furious words rang with an ominous echo of his father's ruthlessness.

The man facing Kheda took a step back, sword lowered warily. 'We were told of invaders on the walls.'

'In the inner citadel?' Orhan's voice was cold with disbelief. 'With no breach of the outer defences?'

'There's word of magic attacking in the south.' The warrior still didn't sheathe his blade. 'Who knows where wizards might appear?'

You're very bold in defying the domain's heir apparent. You've had your orders from someone close enough to Safar to be the warlord's mouthpiece.

All the same, Kheda risked a glance backwards and saw Orhan was in armour of his own, a troop of mailed men at his back. The boy had come prepared to fight.

'Ulla Orhan, I am going to the landing stage, to signal to my galley to take us back on board,' Kheda told him forcefully. 'I am not risking my people's safety any further in a night of such confusion.'

'I will not gainsay you,' said Orhan tightly. 'Much as it grieves me to see my father's fortress embarrassed by such inadequacy.'

'Back off,' Gal snarled at the swordsmen blocking their path.

The warrior took a pace backwards. Kheda took one forwards, Gal at his shoulder, his breathing harsh in the tense silence. Behind, he heard Orhan giving some low-voiced order and the rattle of mail as one of his men ran off, doubtless to carry a message to some ally. To their fore, the armoured man gestured to those behind him and they melted away, leaving the parapet clear.

'I shall not forget this.' Kheda's tone was neutral as he wiped sweat from his forehead. 'Any of this.'

'Nor shall I.' Orhan blinked slowly. Then noises below prompted a new concern into his eyes. 'Did someone fall?'

'Dyal, one of my men. Tend him well because I'll be holding you to account for him.' Kheda turned to continue his race along the parapet.

Let Orhan prove his good faith with decent care for Dyal, if he's not already dead.

Whatever word had gone out, it saved Kheda and Gal from further challenge, each watchtower opening almost before they reached it, sentries standing aside with their faces an eloquent mix of shame and apprehension. Kheda counted off the turrets as he and Gal passed through them, chest heaving when he finally reached one that would give him a suitable vantage point over the river, the toothed expanse of the landing stage far below. 'Signal lantern,' he snapped at the cowering guard.

Snatching it from the man, Gal climbed the ladder to the trap door opening on to the roof of the tower. Kheda hurried after him, three steps to one stride. Gal set the heavy lantern in its high seat, the brilliance painful to their eyes. Kheda pulled the lever that closed the shutters set into the lantern's sides. Counting the beats of his heart, he snapped the light open again, closed and then open, in the sequence that the Rainbow Moth's captain should recognise. He peered through treacherous darkness, a few scant lights marking out the profusion of huts and shelters on the bank beyond the anchorages. His own vision was a confusion of false glimmers prompted by the lantern's dazzle. 'Gal, can you see anything?'
