Up the River by Oliver Optic

In a few minutes our bow and stern lines were fast to the wharf where the Shepards were waiting for their steam-yacht. Owen leaped ashore before the vessel was fairly alongside, though he had not yet come to a full comprehension of what had happened. He knew something was the matter, but he could not tell what it was.

As soon as the Sylvania was made fast I went on shore. Colonel Shepard seemed to be bewildered, for Owen had just told him the Islander had gone down the river. The rest of the family were quite as much astonished as the husband and father. Chloe, the colored servant, was actually wringing her hands, as though she feared another conspiracy was about to be developed.
