Shadows In The Moonlight by Robert E. Howard

The sun was hanging low when Olivia regained her senses. A faint wind wafted to her ears distant shouts and snatches of ribald song. Rising cautiously, she looked out across the plateau. She saw the pirates clustered about a great fire outside the ruins, and her heart leaped as a group emerged from the interior dragging some object she knew was Conan. They propped him against the wall, still evidently bound fast, and there ensued a long discussion, with much brandishing of weapons. At last they dragged him back into the hall, and took up anew the business of ale-guzzling. Olivia sighed; at least she knew that the Cimmerian still lived. Fresh determination steeled her. As soon as night fell, she would steal to those grim ruins and free him or be taken herself in the attempt. And she knew it was not selfish interest alone which prompted her decision.

With this in mind she ventured to creep from her refuge to pluck and eat nuts which grew sparsely near at hand. She had not eaten since the day before. It was while so occupied that she was troubled by a sensation of being watched. She scanned the rocks nervously, then, with a shuddering suspicion, crept to the north edge of the cliff and gazed down into the waving green mass below, already dusky with the sunset. She saw nothing; it was impossible that she could be seen, when not on the cliff's edge, by anything lurking in those woods. Yet she distinctly felt the glare of hidden eyes, and felt that something animate and sentient was aware of her presence and her hiding-place.
