Lloyd lowered the glass which he was about to fill, and said:

‘Kenrick! But he was here only the other day. Or rather, when I say only the other day, I mean a week or two ago. Quite lately, anyway. Why should he have an alias?’

‘I don’t know that myself. I am making inquiries about him on behalf of his friend. He was due to meet his friend in Paris at the beginning of March. On the 4th, to be exact. But he didn’t turn up. We have discovered that he died as the result of an accident on the very day that he should have turned up in Paris.’

Lloyd put the glass slowly down on to the table.

‘So that is why he did not come back,’ he said in that querulous voice that did not mean to be querulous. ‘Poor boy. Poor boy.’

‘You had arranged to see him again?’

‘Yes. I thought him charming and very intelligent. He was bitten with the desert—but perhaps you know that. He had ideas about exploring. A few young men still have. There are still the adventurers, even in this hedged and garnished world. Of which one must be glad. What happened to Kenrick? A car smash?’

‘No. He had a fall on a train and fractured his skull.’

‘Poor wretch. Poor wretch. A pity. I could have supplied the jealous gods with a dozen more expendable in his place. An atrocious word: expendable. The expression of an idea that would not even have been conceivable a few years ago. So far have we progressed towards our ultimate barbarism. Why did you want to know if the Kenrick boy had come to see me?’

‘We wanted to pick up his trail. When he died he was masquerading as Charles Martin, with a complete set of Charles Martin’s papers. We want to know at what stage he began to be Charles Martin. We were almost certain that, being bitten by the desert, he would come to see some authority on the subject in London, and since you, sir, are the ultimate authority we began with you.’
