One of the Ultra Gym machines was operating. In the middle of its pumping hydraulic arms and reciprocating cams, I could see a human figure. "Mr. Montgomery, welcome," the figure called out, A strong male voice, as steady as if the owner were ensconced in an easy chair and not exercising his guts out. "Please, come over. I hope you haven't taken offense at the, shall we say, irregular manner of my invitation, but I didn't think you'd accept if I offered it through normal channels."
