I sounded like my mother then, and instantly regretted my tone.
'Of course it's very unusual to find a house of this age in London. Rather a surprise, in fact.' He walked past me into the hallway, and went up to the basement door.
'You can't,' I said. 'It's locked.' But as I spoke, he turned the handle and the door opened. He seemed to have no fear of the darkness below, but I followed him down the stairs more hesitantly. 'Do you think,' I whispered, 'there might be rats?'
'Of course. Enormous ones.' It did not seem peculiar at the time, but there was no smell, no odour of dampness, no suspicion of rotting things. Then something moved softly across my face, and I stumbled backwards with a cry; Daniel laughed, and pulled what was the cord of an electric light.
'Quite a little screamer, aren't we?' The basement room could be clearly seen now, with its stone floor, its whitewashed walls and its shallow alcoves, all seeming to ebb and flow in the sudden light; it covered the whole area of the house, and yet it was completely empty. Daniel had walked over to one of the walls. 'There was a door here, Matthew. Do you see how it has been sealed up?' He turned around, delighted to be in this ancient enclosed space. 'It looks westward, so it must have opened out near the Fleet River.'
'O gliding down with smooth and subtle course.'
'What?' He looked at me in surprise for a moment, but I just shrugged my shoulders. 'Now do you see this?' He pointed to some marks above the door, where the lintel must once have been, and his pale, carefully manicured hands seemed almost transparent against the white wall.
'Aren't they just scratches?'
He examined them more closely, although in fact very little could now be traced. 'No. They look like symbols.'
'Builders' marks.' I put my hand up to my sweating face.
'Do you know what I think? This wasn't a basement at all. This was the ground floor, and it has slowly sunk through the London clay. This old house is descending into the ground.'

We were sitting upstairs again, although my sense of what was above or below the ground was now subtly confused, and I was apologizing for having fainted away. I blamed it upon my hunger.
'You didn't faint,' he said. 'You just closed your eyes and leaned against the wall. It was all very restrained.' He was looking at me intently but it was impossible to gauge what, if any, feeling lay behind that steady gaze. 'I do think, Matthew, that we ought to find out who owned this house. It's almost a professional duty.'
'I'm not sure that I want to know.' I was very restless and, rising from my chair, I went over to a side-table which had been pushed beneath one of the narrow windows in this ancient room; it opened on to the west, in the same position as the door in the basement, and through the dusty pane I examined the area of the Fleet River where the Farringdon Road now flowed. My hands were upon the polished wooden table, and I could feel the handle of a drawer; I looked down, opened the drawer, and saw a glass tube lying there. It resembled a test tube from a laboratory, but it was about two feet in length and seemed curiously distorted at the end. I was disgusted by it, and closed the drawer quickly. 'It's very close in here,' I said to Daniel. 'Shall we go for a meal?'
He did not answer, so I turned to face him. He was no longer there. He had vanished, and in a sudden panic I rushed out of the room; only to see him coming down the staircase with a smile of triumph. 'I just had to look around,' he said. 'I did ask permission, but you were miles away.'
'I don't...'
'You were lost somewhere. Looking out of the window. So I took matters into my own hands. Did I hear you say something about going out?'
I looked back at the house as we left, and noticed for the first time that the eighteenth-century façade of the ground floor had been designed as a casing or shell for the sixteenth-century interior. I understood then that it had truly become my
