There was no escape that way. From the northern and eastern edges of the forest sheer cliffs fell away into bluish depths where forests looked like lawns and the low uplands of the Alsatian border resembled hillocks made by tunnelling moles. And yet it was from somewhere not far away that a man once had been, carried safely into Alsace on a sudden snowslide. That man now lay among the trees on the crag's edge looking down into the terrific chasm below. He and the girl who crouched in the thicket of alpine roses behind him seemed a part of the light-flecked forest--so inconspicuous were they among dead leaves and trees in their ragged and weather-faded clothing.
They were lean from physical effort and from limited nourishment. The skin on their faces and hands, once sanguine and deeply burnt by Alpine wind and sun and snow glare, now had become almost colourless, so subtly the alchemy of the open operates on those whose only bed is last year's leaves and whose only shelter is the sky. Even the girl's yellow hair had lost its sunny brilliancy, so that now it seemed merely a misty part of the lovely, subdued harmony of the woods.
The man, still searching the depths below with straining, patient gaze, said across his shoulder: "It was here somewhere--near here, Yellow-hair, that I went over, and found what I found.... But it's not difficult to guess what you and I should find if we try to go over now."
"Death?" she motioned with serene lips.
He had turned to look at her, and he read her lips.
"And yet," he said, "we must manage to get down there, somehow or other, alive."
She nodded. Both knew that, once down there, they could not expect to come out alive. That was tacitly understood. All that could be hoped was that they might reach those bluish depths alive, live long enough to learn what they had come to learn, release the pigeon with its message, then meet destiny in whatever guise it confronted them.
For Fate was not far off. Fate already watched them--herself unseen. She had caught sight of them amid the dusk of the ancient trees--was following them, stealthily, murderously, through the dim aisles of this haunted forest of Les Errues.
These two were the hunted ones, and their hunters were in the forest--nearer now than ever because the woodland was narrowing toward the east.
Also, for the first time since they had entered the Forbidden Forest, scarcely noticeable paths appeared flattening the carpet of dead leaves--not trails made by game--but ways trodden at long intervals by man--trails unused perhaps for months--then rendered vaguely visible once more by the unseen, unheard feet of lightly treading foes.
