Czar's Spy The Mystery of a Silent Love (version 2)-William Le Queux

Professor Pierre Aronnax is an academic whose thirst for knowledge carries him out of his ivory tower and on the trail of a mysterious sea beast. His curiosity at last is satiated when he finds himself in the belly of the beast-- that is, on board the incredible submarine the Nautilus, courtesy of its mysterious pilot Captain Nemo and in the company of his servant Conseil and sailor Ned Land.
