CHAPTER I

A SPIRIT CAGED

The room was strange as the man, himself, who dwelt there.  It seemed, in a way, the outward expression of his inner personality.  He had ordered it built from his own plans, to please a whim of his restless mind, on top of the gigantic skyscraper that formed part of his properties.  Windows boldly fronted all four cardinal compass-points—­huge, plate-glass windows that gave a view unequaled in its sweep and power.

The room seemed an eagle’s nest perched on the summit of a man-made crag.  The Arabic name that he had given it—­Niss’rosh—­meant just that.  Singular place indeed, well-harmonized with its master.
