A strange mixture of trance and willfullness, of dream and waking, of aimless wandering and purposeful tramping, gripped Thorn as he adventured down that black-fringed ghost-trail. Odd memories of childhood, of old hopes and desires, of student days with Clawly, of his work and the bewildering speculations it had led to, drifted across his mind, poignant but meaningless. Among these, but drained of significance, like the background of a dream, there was a lingering picture of the scene he had left behind him in the Sky Room. He was conscious of somehow having deserted a friend, abandoned a world, betrayed a great purpose—but it was a blurred consciousness and he had forgotten what the great purpose was. Nothing seemed to matter any longer but the impulse pulling him forward, the sense of an unknown but definite destination. He had the feeling that if he looked long enough at that receding, beckoning point a dozen yards ahead, something would grow there. The forest path was narrow and twisting.

For almost as long as he could remember, that dream Thorn had tainted his life—the specter at his feasts, the suppliant at his gates, the eternal accuser in the courts of inmost thought—drifting phantom-wise across his days, rising up starkly real and terrible in his nights. During the long, busy holiday of youth, when every day had been a new adventure and every thought a revelation, that dream Thorn had been painfully
