So a little more time was wasted in making friends with the Marseilles officials; but this time Grant spent no energy on conscientiously-unofficial methods. He produced his credentials and asked for a loan of the papers. He drank a sirop, and signed a receipt. And he caught the afternoon plane to London on Friday afternoon.

He had two more days. Or one day and a Sunday, to be accurate.

France was still a jewelled pattern as he flew back over it, but Britain seemed to have disappeared altogether. Beyond the familiar outline of the western European coast there was nothing but an ocean of haze. Very odd and incomplete the map looked without the familiar shape of that very individual island. Supposing there never had been that island: how different would the history of the world have been? It was a fascinating speculation. An all-Spanish America, one supposed. A French India; an India without a colour-bar and so racially intermarried that it had lost its identity. A Dutch South Africa ruled by a fanatic Church. Australia? Who would have discovered and colonised Australia? The Dutch from South Africa, or the Spaniards from America? It was immaterial, he supposed, since either race would in a generation have become tall, lean, tough, nasal, drawling, sceptical and indestructible. Just as all Americans eventually began to look like Red Indians even if they entered the country as broad large-boned Saxons.

They dropped into the ocean of cloud and found Britain again. A very mundane, muddy, and workaday place to have changed the history of a world. A steady drizzle soaked the land and the lieges. London was a water-colour of grey reflections with spots of vermilion oil paint where the buses plunged dripping through the haze.

All the lights were on in the finger-print department although it was still daylight; and Cartwright was sitting just as he had last seen him—as he had always seen him—with a half-drunk cup of cold tea at his elbow, the saucer filled with cigarette butts.

‘Something I can do for you this beautiful spring afternoon?’ Cartwright said.

‘Yes. There is one thing I want very much to know. Have you ever drunk the second half of a cup of tea?’

Cartwright considered this. ‘Come to think of it, I don’t know that I ever have. Beryl usually takes my cup away and fills it up with fresh stuff. Something else off the cuff? Or is this just a social call?’

‘Yes, something else. But you’ll be working for me on Monday, so don’t let your sense of benevolence get out of hand.’ He put Charles Martin’s papers on the table. ‘When can you do these for me?’

‘What is this? French identity papers. What are you getting into—or do you want to keep it to yourself?’
