The moon was rising, and besides there was that curious sheen from the sea which you will often notice in spring. The glow was maybe a hundred yards distant, a little spark of fire I could have put in my cap, and, from its crackling and smoke, composed of dry seaweed and half-green branches from the burnside thickets. A man’s figure stood near it, and as we looked it moved round and round the fire in circles which first of all widened and then contracted. The sight was so unexpected, so beyond the beat of our experience, that we were all a little scared. What could this strange being want with a fire at half-past eight of an April Sabbath night on the Dyve Burn sands? We discussed the thing in whispers behind a boulder, but none of us had any solution. “Belike he’s come ashore in a boat,” said Archie. “He’s maybe a foreigner.” But I pointed out that, from the tracks which Archie himself had found, the man must have come overland down the cliffs. Tam was clear he was a madman, and was for withdrawing promptly from the whole business. But some spell kept our feet tied there in that silent world of sand and moon and sea. I remember looking back and seeing the solemn, frowning faces of the cliffs, and feeling somehow shut in with this unknown being in a strange union. What kind of errand had brought this interloper into our territory? For a wonder I was less afraid than curious. I wanted to get to the heart of the matter, and to discover what the man was up to with his fire and his circles. The same thought must have been in Archie’s head, for he dropped on his belly and began to crawl softly seawards. I followed, and Tam, with sundry complaints, crept after my heels. Between the cliffs and the fire lay some sixty yards of _débris_ and boulders above the level of all but the high spring tides. Beyond lay a string of seaweedy pools and then the hard sands of the burnfoot. There was excellent cover among the big stones, and apart from the distance and the dim light, the man by the fire was too preoccupied in his task to keep much look-out towards the land. I remember thinking he had chosen his place well, for save from the sea he could not be seen. The cliffs are so undercut that unless a watcher on the coast were on their extreme edge he would not see the burnfoot sands.
