At two o'clock on May morning a fishing-boat, with a small row-boat in tow, stole up the harbour between the lights of the vessels that lay at anchor. She came on a soundless tide, with her sprit-mainsail wide and drawing, and her foresail flapping idle; and although her cuddy-top and gunwale glistened wet with a recent shower, the man who steered her looked over his shoulder at the waning moon, and decided that the dawn would be a fine one.
