Uncle Montague gave me a light to guide my way, of course, but though this banished some of the darkness ahead of me, I was all too aware of the awful blackness behind me.
And locked inside the cramped lavatory I did not feel any more secure. There was a hole under the washbasin that I always found unsettling, having always had the foolish impression that something was peeping out and then retracting back into the shadows when I glanced down. A large web per- petually occupied a corner of the ceiling, though I never saw its maker.
As soon as I was done and my hands washed as well as they could be in the coffee-coloured water that ran from my uncle's taps, I moved to unbolt the door - I always ensured the bolt was fully home - and make the return journey with as much urgency as the outward bound one.
But just as I was about to pull back the bolt, the door handle was given a vigorous rattle from the outside. The noise and sudden movement of the handle startled me to such a degree that I almost fell backwards on to the lavatory seat.
'Hello?' I said. 'Uncle?'
Again the door handle was given a shake and the door was pulled with such strength I feared the bolt would not hold.
'Franz?' I said. 'I shall only be a moment.'
A long period of silence followed where I pressed my ear to the door and tried to detect any activity outside. I could not rightly say what disturbed me more - the rattling at the door, or the fact that it seemed so disembodied. What I did know was that I could not stay in the lavatory for ever.
I slid the bolt and opened the door. Peeping nervously out, I looked one way up the long corridor and then the other. For as far as I could see - which was not far - there was nothing to see. I stepped out and began at once to march off in the direction of my uncle's study.
As ridiculous as it may sound, I was invariably seized with a strange dread of losing my way in that house. This sense of foreboding was heightened by the fact that I would be pursued by the mournful noise that came from the house's ancient plumbing when the chain was pulled on the huge and grotesquely ornate cistern. I was followed along the hallway by a noise that sounded as though a large animal had been caught in some kind of steam-driven machinery.
The enormous shadow I cast seemed to be racing me, trying to overtake me as I sped along, and a scuttling sound - which may have been Franz, though I never did look round to see - echoed around the corridor, as if something were running up and down the walls. I burst rather dramatically back into my uncle's study, panting with relief.
'Is everything all right?' asked Uncle Montague.
'Yes, Uncle,.' I said. 'Of course. That is, there did seem to be someone trying the door of the lavatory.'
'Was there now?' said my uncle, staring off at the study door and frowning. 'Did you see anyone, Edgar?'
'No, sir,.' I said. 'I expect it was Franz.'
Uncle Montague nodded.
'It could have been.'
'After all, sir,.' I added, 'you said we were alone in the house.'
'Did I?' Uncle Montague murmured.
I put the lamp on the small table by the door and was about to join my uncle by the fire when I noticed something I had not seen before: a framed pen and ink drawing of some foreign landscape.
It was the kind of drawing that pulls you in to look at it and my uncle joined me in my examination of its skilful cross-hatching.
'Ah,.' said my uncle. 'That is an Arthur Weybridge.'
The name meant nothing to me, but I raised my eyebrows and tried to look impressed.
'Where is it a picture of?' I asked.
'A small village in south-eastern Turkey. Have you been to Turkey, Edgar?'
'No, Uncle,.' I said. I had been nowhere but to school and back, and though my uncle should have known this by now, I rather liked the way he always asked.
'Well, you must,.' he said. 'You really must. Does your father have no interest in travel?'
'He likes to go fishing in Scotland,.' I said after a moment's thought. 'But he never takes me. He says I would get bored.'
'And he is probably correct,.' said Uncle Montague with a half-smile.
'Do you still travel, sir?' I asked.
Uncle Montague shook his head.
'No, Edgar,.' he said. 'I used to, once upon a time.
But now I must stay here.'
It seemed an odd thing to say - that he must stay in that house. My uncle had always struck me as a man of some means and I could think of nothing that should prevent his leaving. But then I wondered if he was referring to a medical condition I was unaware of. It might certainly explain much of his curious behaviour. I began to wonder if it had been he who had rattled the lavatory door handle.
'Are you quite well, Uncle?' I asked.
To my enormous surprise, after an initial silence he burst into a sustained bout of laughter. I could not think why what I had said caused my uncle such unrestrained amusement and it only confirmed my suspicion that his mind was troubled.
'You think me deranged, do you not, Edgar?' he said, taking me by surprise by his apparent access to my thoughts.
'No, Uncle,.' I said a little unconvincingly. 'You are tired perhaps?'
Uncle Montague grimaced.
'Yes, Edgar,.' he said almost under his breath. 'I am very tired indeed.'
'Should I go and fetch Franz?' I suggested, moving towards the door.
'No!' said Uncle Montague forcefully, grabbing my arm. 'Franz does not like . . . visitors.' He let go of my arm and I was lost as to what I should do for the best. Uncle Montague looked at me and sighed.
'My apologies, Edgar,.' he said with a weak smile. 'I did not mean to startle you. Perhaps if we sat awhile by the fire?'
'Of course, Uncle,.' I said, and we both walked to our respective chairs.
We sat there in silence, the fire gasping and hissing, the clock ticking. My uncle began to drum the ends of his long fingers together rhythmically and I stifled a yawn.
'Since we are here, Edgar,.' he said suddenly, making me jump, 'I could tell you about the drawing.'
'The drawing on the wall? Very well, Uncle,.' I said. 'If it would not exhaust you.'
Uncle Montague sank back into the shadows.
'No, Edgar,.' he said. 'Thank you. I would rather be occupied. If you are willing to listen, then I am willing to tell the tale.'
Francis Weybridge was bored. His father, Arthur Weybridge, found this boredom intensely annoying, but being a mild-mannered Englishman, he expressed his annoyance by humming a little tune to himself and tapping his shoes on the gravel beneath their table.
The Weybridges, father and son, were seated in the tea garden beside the sacred carp pools in the town of Urfa in south-eastern Turkey in the twilight days of the Ottoman Empire. The sun had already disappeared over the nearby minarets and swallows were gathering to roost among the branches of the surrounding trees, squabbling noisily over their perches.
'I fail to see how anyone could be bored,.' said Mr Weybridge. 'You are at the city once known as Edessa, the birthplace of Abraham, a place mentioned in both the Bible and the Qur'an. Look about you,.' said Mr Weybridge with a theatrical flourish. 'Do you really mean to tell me that you find this dull?'
Francis made no reply but closed his eyes and sighed deeply, causing his father to hum once again, but this time a little faster. When Francis opened his eyes he saw a cat stealing up the tree beside them, disappearing behind the trunk and reappearing ten feet above their heads in the crook between two branches.
'So far on this journey,.' said Mr Weybridge, 'you have been privileged enough to see Istanbul - the fabled Constantinople, jewel of Byzantium. You have stood beneath the great dome of Haghia Sophia. You have sailed along the Black Sea to Trebizond. You have travelled in the footsteps of Alexander the Great. Was it all "boring"?'
'Not all,.' said Francis.
'Well, then,.' said his father. 'I'm pleased to hear that, at least.'
It had not all been boring. Near Van he had seen a shepherd with a huge dog that wore a terrifying spiked collar. His father had told him it was probably to protect it from wolves. But this had been a small reward for such a tedious trip.
Francis looked up again. The cat edged along the branch above their heads. Now Francis could see the reason for the frantic jostling for position of the roosting swallows: none of them wanted to be at the end near the tree trunk. The cat lunged forward, grabbed a swallow in its teeth and scurried down the tree with its prize.
'This land is extraordinary, Francis,.' said his father, lighting one of the noxious Turkish cigarettes he had developed a taste for. 'Wave after wave of civilisations have washed across its surface, and yet there is still something primeval about it.
'Jews, Christians and Muslims have all lived here and left their mark, but there is always the pull of something older, darker, more mysterious. Do you know there were pagans in Harran until the twelfth century?'
Francis had learned that any answer resulted in a lecture, so he kept quiet. Harran was a town nearby they had visited the week before. It was full of beehive-shaped houses and was mentioned in the Bible. Francis had sat in the shade, watching his father draw while children buzzed about them asking for sweets.
It was here that Arthur Weybridge had been told of a village that was just as ancient and just as picturesque, but that no one ever went to. They would be visiting the village tomorrow, and Francis was not keen.
His father paid for their drinks and they walked back to the hotel. They ate well and Arthur Weybridge drank two gin and tonics, as was his custom, after which he began to tell Francis a long anecdote about his journey through the Russian steppes. It involved a Cossack and a three-legged dog and Arthur had already told it in Erzerum.
'I'm tired, Father,.' said Francis, rising to his feet.
'I think I'll turn in.'
'Good idea,.' said his father, downing the rest of his gin. 'We have a tiring day ahead. Goodnight then, Francis.'
'Goodnight, Father.'
They left in the morning after a breakfast of bread, honey and olives, the hotel manager's brother-in-law, Mehmet, driving them out of Urfa at bone-jarring speed in a rather ornate black carriage Mehmet told them he had won from a Frenchman two years earlier in a game of backgammon.
The village was on a track branching off from the main desert road to Syria. Francis's father had intended to draw the traditional houses and the nearby Roman ruins, but as they arrived they saw policemen standing around.
Mehmet told them to stay in the carriage and went to find out what was happening. Moments later he returned with a man who introduced himself as the chief of police and told them that there had been a terrible accident: a boy had been attacked by a wild animal - a wild dog probably - and had been tragically killed. He could not be responsible for their safety while the beast was at large. He respectfully advised Mr Weybridge to draw somewhere else.
As Mehmet turned the carriage round, Francis saw the body under a blanket, a bloody hand exposed. He had seen, too, the looks on the faces of the children standing among the houses and wondered what secrets they were hiding. It was clear to him they were hiding something.
In fact, Francis had the distinct impression that even the chief of police was lying to them. He distinctly heard a boy nearby say 'gin'. Maybe the boy was not killed by animals at all but by a drunken father and they were trying to cover it up. But murder or wild animal, it was a lot more interesting to Francis than minarets and Roman temples.
'Father,.' said Francis as they sat that evening in the hotel tea garden. 'Can we go back to that village? The one where the boy was killed.'
'Well, the police chief told us not to,.' said Mr Weybridge. 'You have to be careful with these chaps, Francis. Why?'
'It just seemed interesting,.' said Francis. 'I mean, there was just something about it. I can't say what. It seemed special somehow.'
Mr Weybridge smiled. At last! At last, Francis seemed to have been moved by something. 'I'll see what I can do,.' he said.
The next day Mehmet reluctantly drove them back to the village. He had been talkative and irrepressibly jovial on their previous trip, but today he was sullen and tense. He had only agreed to take them at all because Arthur had paid him three times what he had the last time before they set off.
Mehmet clucked and flicked the reins, bringing the carriage into the shade of an old barn and the Weybridges got out. Francis followed his father about the village until he found the right spot for his drawing and opened up his camping stool and began to unpack his bag, taking out a wooden pencil box, a bottle of Indian ink, a pen and a sketchbook.
Francis had never been interested in his father's work, and now, after these past weeks, he felt something beyond boredom, something trance-like in which he would sit and let his eyes go out of focus and drift away into blankness.
Francis instantly regretted requesting that they return. Without the body, this village was even more dull than Harran. He was so sick of trailing round this godforsaken country. He felt as though he were being punished, and it all went back to 'the incident'. Everything had been different since then.
'The incident', as his father always referred to it, happened at school. A boy called Harris had taken a dislike to Francis and, over the course of a few months, name-calling and baiting had turned to casual blows and sustained beatings.
Instead of receiving the sympathy he had expected from his father, Mr Weybridge told his son that this was all part and parcel of school life and he would never be a man if he did not stand up for himself. He must deal with it. That was life.
So, one Sunday, after chapel, Francis waited for Harris with a cricket stump as he was walking past the tennis courts and attacked him without warning.
Francis had almost not gone through with it, having a terror that Harris would simply take the weapon from him and give him a thrashing with it, but Francis was overjoyed to find that his very first blow seemed to have knocked Harris senseless.
Laughing triumphantly, Francis leaped on the prone figure of Harris, raining down blows on his face and head. On and on he struck, his arm growing tired with the effort, until he was pulled off by a prefect who had heard the sickening thuds and run to Harris's assistance.
Francis's father was called and drove to the school that very afternoon. Francis found his interview with the headmaster, who ranted and slapped the desk so hard his lamp fell to the floor, far more preferable than his interview with his own father, who was quiet, even by his standards, and at his most annoyingly philosophical.
The fact that there were witnesses to testify that Harris had bullied Francis obviously counted for something, but Francis was annoyed to find that everyone seemed far more concerned with the fact that stupid Harris had almost lost the sight in his right eye than with the matter of his bullying. As far as Francis was concerned, he was a hero. Harris was a bully and he had done the school a service.
Most annoying was the attitude of Francis's father, who, having told his son to stand up to Harris, now sided with the teachers, who said that whatever the provocation this was not the behaviour they expected from their students. It was not what an Englishman did, apparently.
If Arthur Weybridge had not been as illustrious an old boy as he was, and such a generous benefactor to his old school, Francis would have been hustled out of school there and then. He was as unpopular with the staff as he was with his peers, but Francis would get another chance. It would be Harris who would go to another school, not he. There was some degree of satisfaction in that.
As it was, it was decided that the best thing for everyone would be if Francis was to leave school for a while and let things calm down a little. Mr Weybridge had been planning a trip to the Ottoman Empire for some time and so resolved to take his son out of school to accompany him. The trip would be an education in itself.
Arthur Weybridge was a bestselling author and illustrator of travel books. He toured the world in his trademark pale linen suit and Panama hat, writing about the places of interest he passed through and crafting his famously dense and meticulous pen and ink drawings as he went.
For his part, Mr Weybridge hoped that his example of industry, enquiry and perseverance might rub off on his wayward son, who, though clearly intelligent, seemed to lack any interests at all. But two months into their journey, this hope was proving a forlorn one.
As his father began to become absorbed in his drawing, Francis's attention was caught by a group of children standing nearby. They were gazing warily off at something that Francis could not see, there being a house blocking his view.
Whatever it was, it was clearly frightening, because Francis could see fear in the faces of some, and a defiant if unconvincing show of fearlessness on the faces of others. He was intrigued to know the source of this unease.
He edged his way round the building until he left its shadow and recoiled, wincing from the sunlight's sudden glare. As he squinted he saw a strange shimmering figure up ahead, expanding and contracting like a reflection in troubled water.
He blinked and when he looked again there was a small girl, about eight years old, thin and hungry looking, dressed in rags. Her face was pale and expressionless, her hair lank.
Francis watched as one of the children picked up a stone and threw it at the girl. By skill or luck, the stone flew with impressive accuracy and struck the girl on the side of the head, above her right ear. Francis smiled and shook his head.
The girl hissed with pain and put her hand to the wound. Francis could see the glistening of blood even from this distance. He stared, fascinated.
Francis invariably watched the activities of those around him with the bored detachment of an audience at a rather dull theatrical performance. He could not have recalled with any certainty if he had ever actually cared about anyone in his whole life, and yet, to his enormous surprise, Francis felt himself taking an interest in this complete stranger.
'Why don't you just back off, you idiot?' he whispered to himself. But the girl stood her ground. Several children dropped to their haunches, looking for stones.
