They were parked on the dark side of Mercury, snug and comfortable in their hemisphere of force that kept out the cold and kept in the air. At one side where force met ground, a tall silvery spacecraft rose like a chimney.

They were three:

Chat Honger was tall, red-headed, and thin faced. He looked as though he were incapable of quieting down, but he was really the type of person who has an incredible amount of patience for things which cannot be performed in a hurry.

Bren Fallow was shorter than Chat Honger, darker, stouter, more round of face and more amiable. Definitely, Bren was the methodical type.

The third man was Scyth Radnor. Scyth was the kind of man who is quick to grasp a new idea and as quick to reduce it to practise. His failing was that he seldom looked deep or planned far ahead. Being quick of mind he preferred to play everything by ear because planning required study, and Scyth felt that study for the sake of study consumed too much time—time that could better be spent in the pursuit of fun and games.

Teach them the language and drop them in Greater New York and they would be lost among Manhattan's millions. Better change their clothing, though. Striped shorts, Greek sandals, a Sam Browne belt across a bare chest, and a Roman toga of iridescent changing hues is not the kind of costume seen on Fifth Avenue.

Aside from their costume they were human to the last detail. Even their speech, when translated, sounded like the human tongue. They used slang, elision, swearwords and poor grammar. They made bum jokes and puns. They sounded more like displaced earthmen than technicians from a culture that had been establishing galactic centers of population for thirty thousand years.

"You're certain?" asked Bren.

Scyth nodded. "Dead certain now. It was that last computation that sold me."
