For while I abhorred the very idea of that book, there was one thing I abhorred more. This was the thought of the collapse of his memory. If anything happened to that the situation was horribly simple. A man who, from having had two memories, passes to not having one at all, is—gently but without any further pother—locked up. And had that been the end of it I don't think I should have had the heart to write Derry's tale.

He came down, shaven, radiant, hungry. I had heard his plunge into the lake three quarters of an hour before. Julia too was fresh as the dew, and ate heartily. So, over coffee and kidneys and bacon, with such offhandedness as I could assume, I asked him point-blank how his book was getting on.

A wave of thankfulness passed over me at his very first words.

"I say, George," he protested, "this is a holiday, you know. Must we talk shop? By sheer strength of will I've put it all on one side for a couple of days, and here you are trying to shove my nose back on to the grindstone again! Bit of a nigger-driver you are.... Well, just for the length of one pipe; after that shop's taboo for the rest of the day. What is it you want to know about it?"

"Oh, just how it's shaping."

He told me. His account of it as far as it had gone, his projection of the continuing portion, were perfectly lucid, reasoned, logical. He brought all his faculties to bear, was completely master of himself. His memory was as clear in both directions as it had been. I tested this by means of one or two questions that otherwise are of no importance here. All was well. My most dreaded fear was removed. Indeed it was I who, at the end of our pipe, had to change the subject.

One awkward, rather shamefaced explanation, however, he did make. This was both to Julia and to myself.

"I ought to say one thing while I'm about it," he said in a halting and embarrassed voice. "I got your note, Julia. I know what you mean. How you tumbled to it I don't know, and I needn't say it's an unspeakable comfort having the two of you. I'm not going to look a gift-horse like that in the mouth, so if you don't mind we won't talk about it. I suppose George told you, though?"

"Yes."

"Then that's all right. Of course he won't tell anybody else. If he'd asked me first I might have kicked a bit, but it's turned out all right, so that's all we need worry about.... Now what are we going to do to-day? Those trout at all muddy, George? Give me a mayfly and let's have a try at one of 'em——"
