THE HUB, a cluster of bubbles in a web of metal, hung in empty space, in that region known to Earthmen as Hither Sagittarius. The owner was Pan Pascoglu, a man short, dark and energetic, almost bald, with restless brown eyes and a thick mustache. A man of ambition, Pascoglu hoped to develop the Hub into a fashionable resort, a glamor-island among the stars - something more than a mere stopover depot and junction point.
