The Filament itself was a huge cylindrical brass stove that sat on the edge of the swimming pool. It was covered with complex dials and switches, and had a hinged brass door in its belly that allowed access to the furnace. Henry, earlier, had rolled up his sleeves and shoveled in sack-loads of coal, enough to heat the pool for at least a day, if not longer. The device belched black, gritty smoke from a wide funnel in its roof and extended two long, brass fingers into the water, over the lip of the pool. These filaments reached almost to the bottom of the pool itself, and through them, superheated liquid was passed in a constant current, warming the surrounding water and causing steam to rise like a wispy veil from the surface, drifting away into the chill winter air. It had cost Gabriel a small fortune, but he had been true to his word. He'd promised his entourage a November pool party, and that was what they were now enjoying. Gabriel himself remained fully clothed.
