Uncertainty

"...How long she lay there she knew not. She had lost count of time; dreamily she looked up at the moonlit sky, and listened to the monotonous roll of the waves.

The invigorating scent of the sea was nectar to her wearied body, the immensity of the lonely cliffs was silent and dreamlike. Her brain only remained conscious of its ceaseless, its intolerable torture of uncertainty.

She did not know!--"
