“I never touched her! I swear it!”

“Touched who?” The sheik left the camels to the Ha’tari and strode into the middle of the small gathering around me.

Jahmeen lowered the knife and the two brothers hauled me around to face their father. Behind him the column of fire continued to boil up into the night, yellow, orange, mottled with darkness, spreading out across the sky, huge despite the fact it would take a whole day to walk back to where it stood.

“This was a Builders’ Sun.” The sheik waved at the fire behind him.

My mind hadn’t even wandered into why or what yet but as the sheik said it I knew that he was right. The night had lit brighter than day. Had we been a few miles closer the tents would have burst into flame, the people outside turned into burning pillars. Who but the ancients had such power? I tried to imagine the Day of a Thousand Suns when the Builders scorched the world and broke death.

“The infidel has despoiled Tarelle!” Mahood shouted pointing at the figure sprawled beneath the robes.

“And killed her!” Jahmeen, waving his knife as if to make up for the fact that this was an afterthought.

The sheik’s face turned wooden. He dropped to the girl’s side and drew back the robe to expose her head. Tarelle chose that moment to sneeze and opened her eyes to fix her father with an unfocused stare.

“My child!” Sheik Malik drew his daughter to him, exposing enough neck and shoulder to give a Ha’tari apoplexy. He fixed me with cold eyes.

“The camels!” Tarelle pulled at her father’s arm. “They . . . he saved me, Father! Prince Jalan . . . he jumped into their path as they charged and carried me clear.”

“It’s true!” I lied. “I covered her with my body to save her from being crushed.” I shook off the brothers’ hands with a snarl. “I got stepped on by the camel that would have trampled your daughter.” In full bluster mode now I straightened out my robes, wishing they were a cavalry shirt and jacket. “And I don’t appreciate having a damned knife held to my throat by the brothers of the woman I protected at great personal risk. Brothers, it must be said, who would currently be on fire at the Oasis of Palms and Angels if I hadn’t been sent to save all your lives!”

“Unhand him!” The sheik shot dark looks at both sons, neither of which actually had hands on me any more, and waved them further back. “Go with Tahnoon and recover our animals! And you!” He rounded on the three retainers, ignoring their injuries. “Get this camp back into order!”

Returning his attention to me, the sheik bowed at the waist. “A thousand pardons, Prince Jalan. If you would do me the honour of guarding my daughters while I salvage our trade goods I would stand in your debt!”

“The honour is all mine, Sheik Malik.” And I returned the bow, allowing my own to hide the grin I couldn’t keep from my face.

An hour later I found myself outside the sheik’s second best tent guarding all four of his daughters who huddled inside, wrapped once more in the ridiculous acreage of their thobes. The girls had three ageing maidservants to attend their needs and guard their virtue, but the trio hadn’t fared too well when the Builders’ Sun lit the night. Two had burns and the third looked to have broken a leg when the blast threw us all around. They were being tended a short distance off, outside the tent sheltering the injured men.

The important thing about the injured was that none of them looked mortally injured. The sands are staggeringly empty: the Dead King might have turned his eyes my way, but without corpses to work with he posed little threat.

I heard my name mentioned more than once as the sisters discussed the calamity in low voices behind me, Tarelle sharing the story of my bravery in the face of stampeding camels, and Lila reminding her sisters that my warning had saved them all. If I hadn’t been stuck outside in tribesman robes that stank of camel and itched my sunburn into a misery I might have felt quite pleased with myself.

The sheik, together with his sons and guards, had gone out amid the dunes to hunt down his precious cargo and the beasts it was tied onto. I couldn’t imagine how they could track the camels in the night, or how they hoped to find their way back to us either with or without them, but that seemed to be firmly the sheik’s problem and not mine.

I stood, leaning into the wind, eyes slitted against the fine grit it bore. During the whole day’s journey a light breeze had blown in across us from the west, but now the wind had turned toward the explosion, as if answering a summons, and strengthened into something that might easily become a sandstorm. The fire in the south had gone, leaving only darkness and questions.
