He gestured towards me, managing to be both respectful and impatient. I shivered in my thin cloak and hurried after him.

I paused at the front of the equipage, startled to find that the horses, great handsome beasts and beautifully kept, were nonetheless scarred, bearing the traces of some trauma about their noses.

“Die Wölfe,” he said, and I realised in horror what he meant.

I replied in German, my schoolgirl grammar faltering only a little. “The wolves attack them?”

He shrugged. “There is not a horse in the Carpathians without scars. It is the way of it here.”

He said nothing more but opened the door to the coach and I climbed in.

Cosmina had mentioned wolves, and I knew they were a considerable danger in the mountains, but hearing such things amid the cosy comforts of a school dormitory was very different to hearing them on a windswept mountainside where they dwelt.

The coachman sprang to his seat, whipping up the horses almost before I had settled myself, so eager was he to be off. The rest of the journey was difficult, for the road we took was not the main one that continued through the pass, but a lesser, rockier track, and I realised we were approaching the headwaters of the river where it sprang from the earth before debouching into the somnolent valley far below.

The evening drew on into night, with only the coach lamps and a waning sliver of pale moon to light the way. It seemed we travelled an eternity, rocking and jolting our way ever upward until at last, hours after we left the little inn on the mountain pass, the driver pulled the horses to a sharp halt. I looked out of the window to the left and saw nothing save long shafts of starlight illuminating the great drop below us to the river. To the right was sheer rock, stretching hundreds of feet to the vertical. I staggered from the coach, my legs stiff with cold. I breathed deeply of the crisp mountain air and smelled juniper.

Just beyond lay a coach house and stables and what looked to be a little lodge, perhaps where the coachman lived. He had already dismounted and was unhitching the horses whilst he shouted directions to a group of men standing nearby. They looked to be of peasant stock and had clearly been chosen for their strength, for they were diminutive, as Roumanians so often are, but built like oxen with thick necks and muscle-corded arms. An old-fashioned sedan chair stood next to them.

Before I could ask, the driver pointed to a spot on the mountainside high overhead. Torches had been lit and I could see that a castle had been carved out of the living rock itself, perched impossibly high, like an eagle’s aerie. “That is the home of the Dragulescus,” he told me proudly.

“It is most impressive,” I said. “But I do not understand. How am I to-”

He pointed again, this time towards a staircase cut into the rock. The steps were wide and shallow, switching back and forth as they rose over the face of the mountain.

“Impossible,” I breathed. “There must be a thousand steps.”

“One thousand, four hundred,” he corrected. “The Devil’s Staircase, it is called, for it is said that the Dragulescu who built this fortress could not imagine how to reach the summit of the mountain. So he promised his firstborn to the Devil if a way could be found. In the morning, his daughter was dead, and this staircase was just as you see it now.”

I stared at him in astonishment. There seemed no possible reply to such a wretched story, and yet I felt a thrill of horror. I had done right to come. This was a land of legend, and I knew I should find inspiration for a dozen novels here if I wished it.

He gestured towards the sedan chair. “It is too steep for horses. This is why we must use the old ways.”

I baulked at first, horrified at the idea that I must be carried up the mountain like so much chattel. But I looked again at the great height and my legs shook with fatigue. I followed him to the sedan chair and stepped inside. The door was snapped shut behind me, entombing me in the stuffy darkness. A leather curtain had been hung at the window-for privacy, or perhaps to protect the passenger from the elements. I tried to move it aside, but it had grown stiff and unwieldy from disuse.

Suddenly, I heard a few words spoken in the soft lilting Roumanian tongue, and the sedan chair rocked hard, first to one side, then the other as it was lifted from the ground. I tried to make myself as small as possible before I realised the stupidity of the idea. The journey was not a comfortable one, for I soon discovered it was necessary to steel myself against the jostling at each step as we climbed slowly towards the castle.

At length I felt the chair being set down and the door was opened for me. I crept out, blinking hard in the flaring light of the torches. I could see the castle better now, and my first thought was here was some last outpost of Byzantium, for the castle was something out of myth. It was a hodgepodge of strange little towers capped by witches’ hats, thick walls laced with parapets, and high, pointed windows. It had been fashioned of river stones and courses of bricks, and the whole of it had been whitewashed save the red tiles of the roofs. Here and there the white expanses of the walls were broken with massive great timbers, and the effect of the whole was some faery-tale edifice, perched by the hand of a giant in a place no human could have conceived of it.

In the paved courtyard, all was quiet, quiet as a tomb, and I wondered madly if everyone was asleep, slumbering under a sorcerer’s spell, for the place seemed thick with enchantment. But just then the great doors swung back upon their hinges and the spell was broken. Silhouetted in the doorway was a slight figure I remembered well, and it was but a moment before she spied me and hurried forward.

“Theodora!” she cried, and her voice was high with emotion. “How good it is to see you at last.”

She embraced me, but carefully, as if I were made of spun glass.

“We are old friends,” I scolded. “And I can bear a sturdier affection than that.” I enfolded her and she seemed to rest a moment upon my shoulder.

“Dear Theodora, I am so glad you are come.” She drew back and took my hand, tucking it into her arm. The light from the torches fell upon her face then, and I saw that the pretty girl had matured into a comely woman. She had had a fondness for sweet pastries at school and had always run to plumpness, but now she was slimmer, the lost flesh revealing elegant bones that would serve her well into old age.

From the shadows behind her emerged a great dog, a wary and fearsome creature with a thick grey coat that stood nearly as tall as a calf in the field.

“Is he?” I asked, holding myself quite still as the beast sniffed at my skirts appraisingly.

“No.” She paused a moment, then continued on smoothly, “The dog is his.”

I knew at once that she referred to her betrothed, and I wondered why she had hesitated at the mention of his name. I darted a quick glance and discovered she was in the grip of some strong emotion, as if wrestling with herself.

She burst out suddenly, her voice pitched low and soft and for my ears alone. “Do not speak of the betrothal. I will explain later. Just say you are come for a visit.”

She squeezed my hand and I gave a short, sharp nod to show that I understood. It seemed to reassure her, for she fixed a gentle smile upon her lips and drew me into the great hall of the castle to make the proper introductions.

The hall itself was large, the stone walls draped with moth-eaten tapestries, the flagged floor laid here and there with faded Turkey carpets. There was little furniture, but the expanses of wall that had been spared the tapestries were bristling with weapons-swords and halberds, and some other awful things I could not identify, but which I could easily imagine dripping with gore after some fierce medieval battle.
