The Grisly Horror by Robert E. Howard

In the darkness of the woodland path McGrath stirred at last, and staggered groggily to his feet. That desperate blow might have crushed the skull of a man whose physique and vitality were not that of a bull. His head throbbed and there was dried blood on his temple; but his strongest sensation was burning scorn at himself for having again fallen victim to John De Albor. And yet, who would have suspected that move? He knew De Albor would kill him if he could, but he had not expected an attack _before_ the rescue of Constance. The fellow was dangerous and unpredictable as a cobra. Had his pleas to be allowed to attempt Constance's rescue been but a ruse to escape death at the hands of McGrath?

McGrath stared dizzily at the stars that gleamed through the ebon branches, and sighed with relief to see that the moon had not yet risen. The pinewoods were black as only pinelands can be, with a darkness that was almost tangible, like a substance that could be cut with a knife.
