Greenslade was now keener even than I was on the chase, and indeed his lean anxious face was uncommonly like an old hound's. I asked him what he was going to do.
"At ten o'clock precisely I start on a walk—right round the head of the Windrush and home by the Forest. It's going to be a thirty-mile stride at a steady four and a half miles an hour, which, with half an hour for lunch, will get me back here before six. I'm going to drug my body and mind into apathy by hard exercise. Then I shall have a hot bath and a good dinner, and after that, when I'm properly fallow, I may get the revelation. The mistake I made yesterday was in trying to think."
It was a gleamy blustering March morning, the very weather for a walk, and I would have liked to accompany him. As it was I watched his long legs striding up the field we call Big Pasture, and then gave up the day to the job of putting Loch Leven fry into one of the ponds—a task so supremely muddy and wet that I had very little leisure to think of other things. In the afternoon I rode over to the market-town to see my builder, and got back only just before dinner to learn that Greenslade had returned. He was now wallowing in a hot bath, according to his programme.
At dinner he seemed to be in better spirits. The wind had heightened his colour, and given him a ferocious appetite, and the 1906 Clicquot, which I regard as the proper drink after a hard day, gave him the stimulus he needed. He talked as he had talked three nights ago, before this business got us in its clutches. Mary disappeared after dinner, and we sat ourselves in big chairs before the library fire, like two drowsy men who have had a busy day in the open air. I thought I had better say nothing till he chose to speak.
He was silent for a long time, and then he laughed not very mirthfully.
"I'm as far off it as ever. All day I've been letting my mind wander and measuring off miles with my two legs like a pair of compasses. But nothing has come to me. No word yet of that confounded cross-bearing I need. I might have heard that tune in any one of a thousand parts of the globe. You see, my rackety life is a disadvantage—I've had too many different sorts of experience. If I'd been a curate all my days in one village it would have been easier."
I waited, and he went on, speaking not to me but to the fire: "I've got an impression so strong that it amounts to certainty that I never heard the words 'Western Highlands.' It was something like it, but not that."
"Western Islands," I suggested.
"What could they be?"
"I think I've heard the phrase used about the islands off the west coast of Ireland. Does that help you?"
He shook his head. "No good. I've never been in Ireland."
After that he was silent again, staring at the fire, while I smoked opposite him, feeling pretty blank and dispirited. I realised that I had banked more than I knew on this line of inquiry which seemed to be coming to nothing… .
Then suddenly there happened one of those trivial things which look like accidents but I believe are part of the reasoned government of the universe.
I leaned forward to knock out the ashes of my pipe against the stone edge of the hearth. I hammered harder than I intended, and the pipe, which was an old one, broke off at the bowl. I exclaimed irritably, for I hate to lose an old pipe, and then pulled up sharp at the sight of Greenslade.
He was staring open-mouthed at the fragments in my hand, and his eyes were those of a man whose thoughts are far away. He held up one hand, while I froze into silence. Then the tension relaxed, and he dropped back into his chair with a sigh.
"The cross-bearing!" he said. "I've got it… . Medina."
Then he laughed at my puzzled face.
"I'm not mad, Dick. I once talked to a man, and as we talked he broke the bowl of his pipe as you have just done. He was the man who hummed the hymn tune, and though I haven't the remotest recollection of what he said, I am as certain as that I am alive that he gave me the three facts which sunk into the abyss of my subconscious memory. Wait a minute. Yes. I see it as plain as I see you. He broke his pipe just as you have done, and some time or other he hummed that tune."
"Who was he?" I asked, but Greenslade disregarded the question. He was telling his story in his own way, with his eyes still abstracted as if he were looking down a long corridor of memory.
"I was staying at the Bull at Hanham—shooting wild-fowl on the sea marshes. I had the place to myself, for it wasn't weather for a country pub, but late one night a car broke down outside, and the owner and his chauffeur had to put up at the Bull. Oddly enough I knew the man. He had been at one of the big shoots at Rousham Thorpe and was on his way back to London. We had a lot to say to each other and sat up into the small hours. We talked about sport, and the upper glens of the Yarkand river, where I first met him. I remember quite a lot of our talk, but not the three facts or the tune, which made no appeal to my conscious memory. Only of course they must have been there."
"When did this happen?"
"Early last December, the time we had the black frost. You remember, Dick, how I took a week's holiday and went down to Norfolk after duck."
"You haven't told me the man's name."
"I have. Medina."
"Who on earth is Medina?"
"Oh Lord! Dick. You're overdoing the rustic. You've heard of Dominick Medina."
I had, of course, when he mentioned the Christian name. You couldn't open a paper without seeing something about Dominick Medina, but whether he was a poet or a politician or an actor-manager I hadn't troubled to inquire. There was a pile of picture-papers on a side-table, and I fetched them and began to turn them over. Very soon I found what I wanted. It was a photograph of a group at a country-house party for some steeplechase, the usual "reading-from-left-to-right" business, and there between a Duchess and a foreign Princess was Mr. Dominick Medina. The poverty of the photograph could not conceal the extraordinary good looks of the man. He had the kind of head I fancy Byron had, and I seemed to discern, too, a fine, clean, athletic figure.
"If you had happened to look at that rag you might have short-circuited your inquiry."
He shook his head. "No. It doesn't happen that way. I had to get your broken pipe and the tune or I would have been stuck."
"Then I suppose I have to get in touch with this chap and find where he picked up the three facts and the tune. But how if he turns out to be like you, another babbler from the subconscious?"
"That is the risk you run, of course. He may be able to help you, or more likely he may prove only another dead wall."
I felt suddenly an acute sense of the difficulty of the job I had taken on, and something very near hopelessness.
"Tell me about this Medina. Is he a decent fellow?"
"I suppose so. Yes, I should think so. But he moves in higher circles than I'm accustomed to, so I can't judge. But I'll tell you what he is beyond doubt—he's rather a great man. Hang it, Dick, you must have heard of him. He's one of the finest shots living, and he's done some tall things in the exploration way, and he was the devil of a fellow as a partisan leader in South Russia. Also—though it may not interest you—he's an uncommon fine poet."
