Without very good grace he turned to his acting second lieutenant. “Mr. Ferris,” he said, “keep all the men aboard and ready. Temeraire, if you have not seen our signal, and a noise begins in the palace, or there is any sign of dragons overhead, go up at once; in the dark you can keep well out of sight for a long time.”

“I will; and you needn’t think I will go away if I do not see your signal for a long time, so do not try and tell me to do just that,” Temeraire said, with a martial light in his eyes.

Thankfully, the Kaziliks went away before nightfall, to be replaced again by lesser guards, another pair of the middle-weight dragons, who, a little shy of Temeraire, stayed back in the grove and did not trouble him; and the moon was little more than a narrow sliver, enough to give them a little light to place their feet by.

“You will remember I rely upon you to keep all the crew safe,” Laurence said to Temeraire softly. “Pray have a care for them, if anything should go awry; do promise me.”

“I will,” Temeraire answered, “but I will not fly away and leave you behind, so you are to promise me that you will be careful, and send for me if there is any trouble; I do not like to stay here, at all, and be left behind,” he finished miserably.

“I do not at all like to leave you, either, my dear,” Laurence said, and stroked the soft muzzle, for Temeraire’s comfort and his own. “We will try not to be long.”

Temeraire made a low unhappy noise, and then he sat up on his haunches, his wings half-spread to conceal his movements from the guardian dragons, and one after another put the appointed party carefully upon the roof: Laurence and Granby; Tharkay; Dunne; Martin; Fellowes, the harness-master, all his spare leather distributed among them in sacks, to rig out the eggs for carrying; and for their lookout Digby, just made midshipman. With Salyer, Dunne, and Hackley all knocked-down, Laurence had been short of junior officers, and the boy had earned it with his steady work, though young for the promotion; it was pleasanter by far to raise him up than the earlier demotions had been, and they began the desperate adventure with a round of spirits and a quiet toast, to the new midshipman, to the success of their enterprise, and lastly to the King.

The slanting roof was uncertain and difficult footing, but they had to keep low in any case, and steadying themselves with their hands they managed to creep over to where the roof met the harem wall, easily wide enough to stand upon; from the height they could look over the whole ferociously labyrinthine complex: minarets and high towers, galleries and domes, courtyards and cloisters, all standing one atop the other with scarcely any break between them, as though the whole had been almost one single edifice, the work of an architect run mad; the roofs white and grey, plentifully broken up with skylights and attic windows, but all of these which they could make out were barred.

A large marble swimming-pool abutted the wall on the far side, very far down, a narrow walkway of grey slate running all around the border and to a pair of open arches: a way in. They dropped a line and Tharkay slipped down first, all of them tense and watching the lit windows for any passing shadow, the dark for any sudden illumination, any sign they had been seen. No cry was raised; they slung Dunne into a loop and Fellowes and Granby let him down together, the rope braced against their hips and hissing softly through their gloved hands; all the rest of them scrambled down after, one at a time.

They crept single-file along the walkway; the light of many windows shone in the water, rippling yellow, and lanterns were shining on the raised terrace overlooking the pool. They reached the archway; they were inside, and oil lamps flickering from niches upon the floor stretched away along a narrow passageway, low-ceilinged and ill-lit by guttering candles, broken up with many doors and stairways. There was a whispering draught like a distant conversation coming into their faces.

They went silently and very fast, as fast as they dared; Tharkay in the lead and Dunne whispering to him about the way, as best he could recall in the darkness. They passed by many small rooms, some still touched with a drifting fragrance, sweet and more fragile than roses, which could only be caught now and again by an accidental breath, and faded into the stronger lingering smell of incense and spice if one tried to draw it in. Throughout, flung upon divans and scattered on the floor, lay the beguilements of the harem’s idle hours, writing-boxes and books and musical instruments, ornaments for the hair, scarves cast aside, the paints and brushes of beauty. Ducking his head through one doorway, Digby gave a startled gasp, and coming to his side they at first reached for their swords and pistols, seeing all around them suddenly a crowd of pale distorted faces: they were looking into a graveyard of old mirrors, cracked and gap-toothed and leaning back against the walls, still in their golden frames.

Now and again Tharkay would halt them, and wave them all into one room or another, to crouch in silence, waiting, until in the distance footfalls died away again; once a few women went by laughing in the hallway, clear high voices ringing with hilarity. Laurence by degrees grew conscious of a heaviness, a moisture in the air, an increase of warmth, and Tharkay looking around caught his eye and nodded, beckoning.

Laurence crept to his side: through a latticework screen they were looking upon a high, well-lit marble hallway. “Yes, that’s where we saw them coming out,” Dunne whispered, pointing at a tall narrow archway; the floor around it was shining and damp.

Tharkay touched a finger to his lips and motioned them back into the darkness; he crept away, vanishing for minutes that seemed endless, then coming back whispered, “I have found the way down; but there are guards.”

Four of the black eunuchs stood in their uniforms at the base of the stairs, idle and drowsy with the late hour, speaking to one another and paying no real attention; but there was no easy way to come towards them without being seen and raising the alarm. Laurence opened his cartridge box and ripped half-a-dozen of the pistol-balls out of their paper twists, scattering the powder upon the ground; they hid to either side of the head of the stairs, and he let the balls go rolling down the stairs, clattering and ringing bright against the smooth marble.

More puzzled than alarmed, the guards came up to investigate and bent low over the black powder; Granby sprang forward, even as Laurence began to give the word, and clubbed one with his pistol-butt; Tharkay another, with a single swift blow to the temple with the pommel of his knife, and lowered him easily to the ground. The third, Laurence caught around the throat with his arm, choking him to silence and then to stillness, but the last, a big man, barrel-chested and thick-necked, managed a strangled shout past Digby’s grasp before Martin struck him down.

They stood all panting, listening, but no reply came, no sound of roused vigilance. They bundled the guards into the dark corner where they themselves had been concealed, and tied and gagged them with their neckcloths.

“We must hurry now,” Laurence said, and they ran down the stairs and the empty vaulted hallway, their boots loud suddenly on the flagstones. The baths were empty, a great room of marble and stone, vaulted far above with delicate pointed arches of warm yellowed stone, great stone basins and golden spigots set in the wall, with dark wooden screens and little dressing alcoves in the many corners, and platforms of stone in the middle of the room, all of it slick with steam and water-beaded. Archways led out of the room all around, and puffs of steam were issuing into the room from vents set high in the walls; a single narrow stairway built of stone led them a winding way up to an iron door, hot to the touch.
