Oh, God! not again. Little Miss Muffet sat on a tuffet eating her curds and whey. Hickory dickory dock.

Ride a cock horse to Banbury Cross—Your imagination had to be caught before you were fired by the need to write down a thing. You could, if your imagination was vivid, get to a stage when you were in bondage to an idea. When it became an idée fixe. You could become so enraptured by the pictured grace of a temple’s flight of steps that you would work for years to earn the money and gain the leisure to take you there. In extreme cases it became a compulsion, and you dropped everything and went to the thing that had seduced you: a mountain, a green stone head in a museum, an uncharted river, a bit of sail-cloth.

Because he had written those pencilled words.

Of course he had written them.

They belonged to B Seven as much as his eyebrows did. As much as those schoolboy capital letters did.

‘ Yes, those English letters.’

‘But he was a native of Marseilles.’

‘He could have been educated in England, couldn’t he?’

‘In two shakes you’ll be telling me that he wasn’t a Frenchman at all.’
