Nightmare-bound, the boy watched their backs, the one huge-shouldered, slouching, the other sprightly and slight as a lad's.
In the one there was no light. He was a vast black body, unlit now even by the moon. The other was radiant beside him. The Angel of Darkness was about to swallow the Child of Light. The boy saw what was going to happen and could not stay it.
Then he heard a sound.
The man was moaning as he walked.
Nelson stopped.
"Aren't you well, Dark?" he asked, so quietly, so kindly.
The giant swayed. Head and eyes were down, arms swinging. He was as a man asleep preparing for a plunge. And his light was out.
Nelson laid a hand upon his shoulder.
"Can I help you?" he asked, with the shy tenderness of a woman.
The groan sighed itself away. Just so must Lazarus have sighed when the life first began to trickle back along disused veins. Slowly the giant pulled himself together, squaring vast shoulders. Then he drew a tremendous breath. In the darkness a tiny star began to glow.
