Then came a wide gap in the range, where the hideous reaches of transmontane Leng were joined to the cold waste on this side by a low pass through which the stars shone wanly. Carter watched this gap with intense care, knowing that he might see outlined against the sky beyond it the lower parts of the vast thing that flew undulantly above the pinnacles. The object had now floated ahead a trifle, and every eye of the party was fixed on the rift where it would presently appear in full-length silhouette. Gradually the huge thing above the peaks neared the gap, slightly slackening its speed as if conscious of having outdistanced the ghoulish army. For another minute suspense was keen, and then the brief instant of full silhouette and revelation came; bringing to the lips of the ghouls an awed and half-choked meep of cosmic fear, and to the soul of the traveller a chill that never wholly left it. For the mammoth bobbing shape that overtopped the ridge was only a head—a mitred double head—and below it in terrible vastness loped the frightful swollen body that bore it; the mountain-high monstrosity that walked in stealth and silence; the hyaena-like distortion of a giant anthropoid shape that trotted blackly against the sky, its repulsive pair of cone-capped heads reaching half way to the zenith.
