As he watched me into the lift I thought of yesterday, Mrs Van Hopper's chattering tongue, and his cold courtesy.
I had ill-judged him, he was neither hard nor sardonic, he was already my friend of many years, the brother I had never possessed.
Mine was a happy mood that afternoon, and I remember it well.
I can see the rippled sky, fluffy with cloud, and the white whipped sea. I can feel again the wind on my face, and hear my laugh, and his that echoed it.
It was not the Monte Carlo I had known, or perhaps the truth was that it pleased me better.
There was a glamour about it that had not been before. I must have looked upon it before with dull eyes.
The harbour was a dancing thing, with fluttering paper boats, and the sailors on the quay were jovial, smiling fellows, merry as the wind.
We passed the yacht, beloved of Mrs Van Hopper because of its ducal owner, and snapped our fingers at the glistening brass, and looked at one another and laughed again.
I can remember as though I wore it still my comfortable, ill-fitting flannel suit, and how the skirt was lighter than the coat through harder wear.
My shabby hat, too broad about the brim, and my low-heeled shoes, fastened with a single strap.
A pair of gauntlet gloves clutched in a grubby hand.
I had never looked more youthful, I had never felt so old.
Mrs Van Hopper and her influenza did not exist for me.
The bridge and the cocktail parties were forgotten, and with them my own humble status.
I was a person of importance, I was grown up at last.
That girl who, tortured by shyness, would stand outside the sitting-room door twisting a handkerchief in her hands, while from within came that babble of confused chatter so unnerving to the intruder — she had gone with the wind that afternoon.
She was a poor creature, and I thought of her with scorn if I considered her at all.
The wind was too high for sketching, it tore in cheerful gusts around the corner of my cobbled square, and back to the car we went and drove I know not where.
The long road climbed the hills, and the car climbed with it, and we circled in the heights like a bird in the air.
How different his car to Mrs Van Hopper's hireling for the season, a square old-fashioned Daimler that took us to Mentone on placid afternoons, when I, sitting on the little seat with my back to the driver, must crane my neck to see the view.
This car had the wings of Mercury, I thought, for higher yet we climbed, and dangerously fast, and the danger pleased me because it was new to me, because I was young.
I remember laughing aloud, and the laugh being carried by the wind away from me; and looking at him, I realised he laughed no longer, he was once more silent and detached, the man of yesterday wrapped in his secret self.
I realised, too, that the car could climb no more, we had reached the summit, and below us stretched the way that we had come, precipitous and hollow.
He stopped the car, and I could see that the edge of the road bordered a vertical slope that crumbled into vacancy, a fall of perhaps two thousand feet.
We got out of the car and looked beneath us.
This sobered me at last. I knew that but half the car's length had lain between us and the fall.
The sea, like a crinkled chart, spread to the horizon, and lapped the sharp outline of the coast, while the houses were white shells in a rounded grotto, pricked here and there by a great orange sun.
We knew another sunlight on our hill, and the silence made it harder, more austere.
A change had come upon our afternoon; it was not the thing of gossamer it had been.
The wind dropped, and it suddenly grew cold.
When I spoke my voice was far too casual, the silly, nervous voice of someone ill at ease.
'Do you know this place?' I said.
'Have you been here before?'
He looked down at me without recognition, and I realised with a little stab of anxiety that he must have forgotten all about me, perhaps for some considerable time, and that he himself was so lost in the labyrinth of his own unquiet thoughts that I did not exist.
He had the face of one who walks in his sleep, and for a wild moment the idea came to me that perhaps he was not normal, not altogether sane.
There were people who had trances, I had surely heard of them, and they followed strange laws of which we could know nothing, they obeyed the tangled orders of their own subconscious minds.
Perhaps he was one of them, and here we were within six feet of death.
'It's getting late, shall we go home?' I said, and my careless tone, my little ineffectual smile would scarcely have deceived a child.
I had misjudged him, of course, there was nothing wrong after all, for as soon as I spoke this second time he came clear of his dream and began to apologise.
I had gone white, I suppose, and he had noticed it.
'That was an unforgivable thing for me to do,' he said, and taking my arm he pushed me back towards the car, and we climbed in again, and he slammed the door.
'Don't be frightened, the turn is far easier than it looks,' he said, and while I, sick and giddy, clung to the seat with both hands, he manoeuvred the car gently, very gently, until it faced the sloping road once more.
"Then you have been here before?' I said to him, my sense of strain departing, as the car crept away down the twisting narrow road.
'Yes,' he said, and then, after pausing a moment, 'but not for many years.
I wanted to see if it had changed.'
'And has it?' I asked him.
'No,' he said. 'No, it has not changed.'
I wondered what had driven him to this retreat into the past, with me an unconscious witness of his mood.
What gulf of years stretched between him and that other time, what deed of thought and action, what difference in temperament?
I did not want to know.
