The Thorn blaster that lay melting on the thick pile of his officer's quarters was the opening shot in the extermination program.

The McCanahan let the breath from his lungs in a sudden relief. He sat with his back propped against the leg of the chair, and the hand that held his own Thorn shook so that he put his wrist on his naked knee. He was a tall man, a man grown hard and fit with the mechanical fitness that was the hallmark of all officers of the Solar Intergalactic Command. Blond hair was cropped close to the conformations of his head, giving his face a hard, carven look.

The mark of deep space was in Kael McCanahan's eyes, and in the catlike walk and movements of his big body. He had been processed as only Spacefleet officers were processed, in these days of the Empire, with a cold precision to his mind and a careful hardness to his body.

He came off the floor and began to dress, sliding into the white uniform with its crimson facings, pushing feet into highly polished jet boots. His mind went to his father, the Sire Patric McCanahan, who was Earth representative at the court of the High Mor, overlord of Senorech.

"If they've made their try for me, they've already made it for him," he told the room.

He buttoned his white jacket that had the golden eagles at collar and cuffs. He whipped the leather service belt around his middle. He fastened the black blaster holster to its pivot.

The door opened to a fingerpress, and he was out in the long, metaloid hall, moving with long strides. A woman came out of the shadows to meet him, running.

"Kael! Kael—wait!"

It was Cassy Garson, in her white nursing uniform that was always a little too tight for her curved body. Like many other Earth officers on the distant planets of the empire, the McCanahan had fond memories of the Nursing Auxiliary of the Fleet. Cassy Garson had been a lot of fun, on a dance floor or under the curved canopy of a canalboat, or on the silken cushions of a reflexifloor.

Her soft hands caught his, and he could feel her body's tremblings as she came against him. "Kael, you've heard! Oh, Kael, I'm scared! What'll they do to us?"
