It was Wisby's turn to be contemptuous. "One of them? Hah! Town loungers! A city dweller from Earth would give you a better fight."

The Martians didn't look impressive. They stood only some four feet high on skinny, claw-footed legs, and the arms, ending in bony four-fingered hands, were stringy. The chests were broad and deep, but the waists were ridiculously narrow. They were viviparous, warm-blooded, and suckled their young, but gray feathers covered their hides. The round, hook-beaked heads, with huge amber eyes and tufted feather ears, showed the origin of the name "owlie." They wore only pouched belts and carried sheath knives; even the liberals of Earth weren't ready to allow the natives modern tools and weapons. There were too many old grudges.

"The Martians always were good fighters," said Riordan. "They wiped out quite a few Earth settlements in the old days."

"The wild ones," agreed Wisby. "But not these. They're just stupid laborers, as dependent on our civilization as we are. You want a real old timer, and I know where one's to be found."

He spread a map on the desk. "See, here in the Hraefnian Hills, about a hundred miles from here. These Martians live a long time, maybe two centuries, and this fellow Kreega has been around since the first Earthmen came. He led a lot of Martian raids in the early days, but since the general amnesty and peace he's lived all alone up there, in one of the old ruined towers. A real old-time warrior who hates Earthmen's guts. He comes here once in a while with furs and minerals to trade, so I know a little about him." Wisby's eyes gleamed savagely. "You'll be doing us all a favor by shooting the arrogant bastard. He struts around here as if the place belonged to him. And he'll give you a run for your money."

Riordan's massive dark head nodded in satisfaction.
