Guy nodded abstractedly.

"You know, I don't think you've heard the whole story," he said.

"I've heard more than I want to," I replied, as I began to consult the programme of the afternoon's proceedings.

"Ah, but only on one side. There was such provocation——"

I laid my hand on Guy's knee.

"That was good enough for her, but it won't do for me," I said. "I've no doubt Grayle worked it up very convincingly, but you're far too clever to be taken in by it and not half clever enough to impose on me. We both of us know that it's impossible to say a single word for either of them. There we'd better leave it. It can't be undone now."

We were interrupted by the chairman's introductory speech, but at the end of the meeting Guy took my arm and walked with me to Cannon Street Station.

"I'm not trying to defend them," he said. "In a thing like this no outsider can give an opinion worth having. I'm only saying that you might be a bit more lenient, if you'd heard both sides."

"It can't be undone now," I repeated.
