My only hope was to sit tight in the glen, and it might involve a wait of days. To wait I must have food, and, though it meant relinquishing guard for a matter of six hours, the risk had to be taken. I set off at a brisk pace with a very depressed mind.
From the map it seemed that a short cut lay over a pass in the range. I resolved to take it, and that short cut, like most of its kind, was unblessed by Heaven. I will not dwell upon the discomforts of the journey. I found myself slithering among screes, climbing steep chimneys, and travelling precariously along razor-backs. The shoes were nearly rent from my feet by the infernal rocks,which were all pitted as if by some geological small-pox. When at last I crossed the divide, I had a horrible business getting down from one level to another in a gruesome corrie, where each step was composed of smooth boiler-plates. But at last I was among the bogs on the east side, and came to the place beside the road where I had fixed my cache.
The faithful Amos had not failed me. There were the provisions -a couple of small loaves, a dozen tins, and a bottle of whisky. Imade the best pack I could of them in my waterproof, swung it on my stick, and started back, thinking that I must be very like the picture of Christian on the title-page of_Pilgrim's _Progress.
I was liker Christian before I reached my destination - Christian after he had got up the Hill Difficulty. The morning's walk had been bad, but the afternoon's was worse, for I was in a fever to get back, and, having had enough of the hills, chose the longer route I had followed the previous day. I was mortally afraid of being seen, for I cut a queer figure, so I avoided every stretch of road where I had not a clear view ahead. Many weary detours Imade among moss-hags and screes and the stony channels of burns. But I got there at last, and it was almost with a sense of comfort that I flung my pack down beside the stream where Ihad passed the night.
I ate a good meal, lit my pipe, and fell into the equable mood which follows upon fatigue ended and hunger satisfied. The sun was westering, and its light fell upon the rock-wall above the place where I had abandoned my search for the spoor.
As I gazed at it idly I saw a curious thing.
It seemed to be split in two and a shaft of sunlight came through between. There could be no doubt about it. I saw the end of the shaft on the moor beneath, while all the rest lay in shadow. I rubbed my eyes, and got out my glasses. Then I guessed the explanation.
There was a rock tower close against the face of the main precipice and indistinguishable from it to anyone looking direct at the face.
Only when the sun fell on it obliquely could it be discovered. And between the tower and the cliff there must be a substantial hollow.
The discovery brought me to my feet, and set me running towards the end of the shaft of sunlight. I left the heather, scrambled up some yards of screes, and had a difficult time on some very smooth slabs, where only the friction of tweed and rough rock gave me a hold. Slowly I worked my way towards the speck of sunlight, till I found a handhold, and swung myself into the crack.
On one side was the main wall of the hill, on the other a tower some ninety feet high, and between them a long crevice varying in width from three to six feet. Beyond it there showed a small bright patch of sea.
There was more, for at the point where I entered it there was an overhang which made a fine cavern, low at the entrance but a dozen feet high inside, and as dry as tinder. Here, thought I, is the perfect hiding-place. Before going farther I resolved to return for food. It was not very easy descending, and I slipped the last twenty feet, landing on my head in a soft patch of screes. At the burnside Ifilled my flask from the whisky bottle, and put half a loaf, a tin of sardines, a tin of tongue, and a packet of chocolate in my waterproof pockets. Laden as I was, it took me some time to get up again, but I managed it, and stored my belongings in a corner of the cave.
Then I set out to explore the rest of the crack.
It slanted down and then rose again to a small platform. After that it dropped in easy steps to the moor beyond the tower. If the Portuguese Jew had come here, that was the way by which he had reached it, for he would not have had the time to make my ascent. Iwent very cautiously, for I felt I was on the eve of a big discovery.
The platform was partly hidden from my end by a bend in the crack, and it was more or less screened by an outlying bastion of the tower from the other side. Its surface was covered with fine powdery dust, as were the steps beyond it. In some excitement Iknelt down and examined it.
Beyond doubt there was spoor here. I knew the Portuguese jew's footmarks by this time, and I made them out clearly, especially in one corner. But there were other footsteps, quite different. The one showed the rackets of rough country boots, the others were from un-nailed soles. Again I longed for Peter to make certain, though I was pretty sure of my conclusions. The man I had followed had come here, and he had not stayed long. Someone else had been here, probably later, for the un-nailed shoes overlaid the rackets.
The first man might have left a message for the second. Perhaps the second was that human presence of which I had been dimly conscious in the night-time.
I carefully removed all traces of my own footmarks, and went back to my cave. My head was humming with my discovery. Iremembered Gresson's word to his friend: 'Tomorrow night.' As Iread it, the Portuguese Jew had taken a message from Gresson to someone, and that someone had come from somewhere and picked it up. The message contained an assignation for this very night. Ihad found a point of observation, for no one was likely to come near my cave, which was reached from the moor by such a toilsome climb. There I should bivouac and see what the darkness brought forth. I remember reflecting on the amazing luck which had so far attended me. As I looked from my refuge at the blue haze of twilight creeping over the waters, I felt my pulses quicken with a wild anticipation.
Then I heard a sound below me, and craned my neck round the edge of the tower. A man was climbing up the rock by the way Ihad come.
