Watch and Wait by Oliver Optic

The deep silence which pervaded the camp was first broken by Dan. He woke slowly from his profound slumbers, looked about him for a moment, then glanced at Cyd, who, contrary to his usual custom, did not snore. Every thing was still; his ear was not saluted with the sharp crack of a slave-hunter's rifle, and no curses disturbed the solemn silence of the place. Every thing seemed to be secure, and he wondered that the enemy had not yet appeared.

He was tempted to turn over and go to sleep, for he still felt very weary, and his repose had not restored his wonted vigor. But he concluded to go on deck, as every prudent skipper should, before he finished his nap. Rising leisurely from his bunk, he made his way to the standing room where he was almost paralyzed at the discovery of Lily lying apparently dead upon the floor.
