impossible to tell, and MacMaine knew it would be useless to read the man's expression. But he watched, nonetheless. 

 In one way, Tallis' face was typically Kerothi. The orange-pigmented skin and the bright, grass-green eyes were common to all Kerothi. The planet Keroth, like Earth, had evolved several different "races" of humanoid, but, unlike Earth, the distinction was not one of color. 

 MacMaine took a drag off his cigarette and forced himself to keep his mind off whatever it was that Tallis might be about to say. He was already prepared for a death sentence—even a death sentence by torture. Now, he felt, he could not be shocked. And, rather than build up the tension within himself to an unbearable degree, he thought about Tallis rather than about himself. 

 Tallis, like the rest of the Kerothi, was unbelievably humanoid. There were internal differences in the placement of organs, and differences in the functions of those organs. For instance, it took two separate organs to perform the same function that the liver performed in Earthmen, and the kidneys were completely absent, that function being performed by special tissues in the lower colon, which meant that the Kerothi were more efficient with water-saving than Earthmen, since the waste products were excreted as relatively dry solids through an all-purpose cloaca. 

 But, externally, a Kerothi would need only a touch of plastic surgery and some makeup to pass as an Earthman in a stage play. Close up, of course, the job would be much more difficult—as difficult as a Negro trying to disguise himself as a Swede or vice versa. 

 But Tallis was— 

 "I would have a word," Tallis said, shattering MacMaine's carefully neutral train of thought. It was a standard opening for breaking the pause of adjustment, but it presaged good news rather than bad. 

 "I await your word," MacMaine said. Even after all this time, he still felt vaguely proud of his ability to handle the subtle idioms of Kerothic. 

 "I think," Tallis said carefully, "that you may be offered a commission in the Kerothi Space Forces." 

 Sebastian MacMaine let out his breath slowly, and only then realized that he had been holding it. "I am grateful, my sibling-by-choice," he said. 

 General Tallis tapped his cigarette ash into a large blue ceramic ashtray. MacMaine could
