'What's your guess?' I asked.

'My guess? I do not guess. I know. He will stay. Just as I know that you do not write a story for the films.'

His eyes were watching me closely. I felt annoyed. The conversation was being taken out of my hands. 'I have not written much yet,' I said, 'because I am absorbing the background.'

'Ah, yes — the background. Yes, that is a good explanation, Mr Blair. A writer can always explain anything he does, however strange, by saying that he seeks the background or the plot or the characters. But do you need an auction for your plot? Have you no better characters in your mind than the Contessa Forelli? You see, I observe. And what I am observing is that you are more interested in what happens around you at Col da Varda than in your skiing story. Is that not so?'

'I am certainly interested,' I said defensively. Then with more attack: 'For instance, I am interested in you, Mr Keramikos.' He raised his eyebrows and smiled. 'You knew Mayne,' I said, 'before you met him last night.' It was a random thrust. I was not sure of myself.

He set down his teacup. 'Ah, you noticed that, eh? You are very observant, Mr Blair.' He considered for a moment. 'I wonder why you are so observant?' he mused. He drank thoughtfully as though considering the matter. 'Wesson is not observant. He is just a cameraman and he works hard taking pictures. Valdini, I know about. And Mayne, too. But you — I am not sure about you.' He seemed to hesitate. 'I will tell you something,' he said suddenly. 'And you will do well to think of it. You are quite right. I recognised Mayne. I had known him before. You do not know much about him, eh? How does he strike you?'

'He seems a pleasant enough fellow,' I replied. 'He is well read, friendly — has an attractive personality.'

He smiled. 'An engaging personality, eh? And he has travelled. He was in the United States during the prohibition days. Later he returned to England and in 1942 he joined the British Army.' He considered a moment. Then he said, 'Would it interest you to know, Mr Blair, that he deserted whilst serving in Italy?'

'How do you know?' I asked.

'He was useful to me in Greece,' Keramikos replied. 'For a time he operated a deserter gang in Naples, a bad crowd, composed of a variety of nationalities. They were cleaned up by the military police in the end. That was when he came to Athens. He operated on his own there as an UNRRA official. He was a very successful UNRRA official.' He smiled and took out a heavy silver watch. 'We must go,' he said, 'or you will miss your bus.' And he rose to his feet and paid the bill. I got up. The hum of voices, the clatter of crockery — all the sounds of the cafe — thrust themselves into my mind so that I wondered whether I had really understood what the Greek had told me.
