"What is that? Oh yes; he's an American. His name? How should I remember! I wasn't interested either in him, or what he had to say. He pretends to have discovered some new agency or force, don't you know, and tries to prove by a lot of double-exposed photographs that he has broken down the fundamental laws of physics, neutralizing the force of gravity, or annihilating space by the polarization of light, or some such rot. "Do not kick him out. He has letters not only from his Government, but from some of its most prominent men whom it would be unwise to offend at this time. Just listen to his twaddle about universal peace and that sort of thing, and then pass him on to Graves with a quiet warning such as I have given you."

He was a man of wealth, with establishments in New York and Newport, at both of which places Edestone had been entertained. His loud and hearty manner stamped him as a typical American, but his large frame, handsome face, and military bearing showed his Teutonic origin. "You surprise me Rebener."
