En route to polite exile in the Galapagos Islands (field work, to quote the dean of my university), I have found myself marooned on a deserted tropical paradise. Deserted, that is, except for my savior, a mysterious American called Marcus. He is an inventor—and the proof of his greatness is the marvelous new clockwork arm he has created to replace the unsightly one that was ruined in my shipboard mishap. Marcus has a truly brilliant mind and the gentlest hands, which cause me to quiver in an unfamiliar but rather pleasant way. Surely it is only my craving for human companionship that draws me to this man, nothing more? He says a ship will pass this way in a few months, but I am welcome to stay as long as I like. The thought of leaving Marcus becomes more untenable with each passing day, though staying would be fatal to my career.
