"What exactly," said Adèle, bubbling, "is the value of controversy?"

"Its unique ability," said Berry, "to produce the truth. The hotter the furnace of argument, the harder the facts which eventually emerge. That's why I never spare myself. I don't pretend it's easy, but then I'm like that. Somebody offers you a drink. The easiest way is to refuse. But I don't. I always ask myself whether my health demands it."

There was an outraged silence.

Then—

"I have noticed," I observed, "that upon such occasions your brain works very fast. Also that you invariably choose the—er—harder path."

"Nothing is easier," said Berry, "than to deride infirmity." Having compassed the Place Royale, we returned to the Boulevard. "And now, if you've quite finished maundering over the beauties of a landscape which you can't see, supposing we focussed on the object with which we set out. I've thought out a new step, I want to show you. It's called 'The Slip Stitch.' Every third beat you stagger and cross your legs above the knee. That shows you've been twice to the Crusades. Then you purl two and cast four off. If you're still together, you get up and repeat to the end of the row knitways, decreasing once at every turn. Then you cast off very loosely."

Happily the speaker was in the other car, so we broke away and fled up the Rue du Lycée….

The dancing-room was crowded. Every English visitor seemed to be there, but they were not all dancing, and the floor was just pleasantly full.

As we came in, I touched Adèle on the arm.

"Will you dance with me, lass?"
