"How much is this?" I asked scornfully.

"Well," said the dealer, "if it were a genuine Turner it would be worth anything. But let's say ten shillings. You can have it for that; but I don't mind if you don't, because I'm going to London next week and should take it with me to get an opinion."

I pondered.

"Mind you, I don't guarantee it," he added.

I gave him the ten shillings.

By what incredible means I found a purchaser for the drawing at fifty pounds there is no need to tell, for the point of this narrative resides not in bargaining with collectors, but in bargaining with my own soul. The astonishing fact remains that I achieved a profit of forty-nine pounds ten and was duly elated. I then began to think.

The dealer (so my thoughts ran) in that little street by the cathedral west door, he ought to participate in this. He behaved very well to me and I ought to behave well to him. It would be only fair to give him half.

Thereupon I sat down and wrote a little note saying that the potential Turner drawing, which no doubt he recollected, had turned out to be authentic, and I had great pleasure in enclosing him half of the proceeds, as I considered that to be the only just and decent course.

Having no stamps and the hour being late I did not post this, and went to bed.

At about 3.30 a. m. I woke widely up and, according to custom, began to review my life's errors, which are in no danger of ever suffering from loneliness. From these I reached, by way of mitigation, my recent successful piece of chaffering, and put the letter to the dealer under both examination and cross-examination. Why (so my thoughts ran) give him half? Why be quixotic? This is no world for quixotry. It was my eye that detected the probability of the drawing, not his. He had indeed failed; did not know his own business. Why put a premium on ineptitude? No, a present of, say, ten pounds at the most would more than adequately meet the case.
