Sinopsis

I put my head down through the hatchway and called to Cynthia to come on deck. I always called her Cynthia to myself. What I said was:
"Come up, Miss Archer; I can see Christophe's castle."
"You can't!" she said. These words were uttered, I was convinced, more in astonishment than in contradiction. They issued from the funnel of a white cotton sunbonnet. The funnel appeared above the hatchcombings, then a pair of shoulders incased in blue dungaree followed suit, and, finally, the tall figure of Miss Cynthia Archer emerged from the open hatchway and stepped lightly on to the deck.
