plenty of the stuff. I'd just as soon let somebody else do it from now on in, but nobody asked me." Harding grunted: "Well, tell me, have you ever served under a sick skipper?" "No." "Do you want to?" "Why not? Besides—what can I do about it?" Harding leaned back and sipped away on the straight whiskey he was drinking, watching me over the top of the glass and talking directly into it, making his voice sound muffled and sinister. "You know, Maise, sometimes you make me tired. Frankly, when they first sent us you, I didn't like it. None of us did.

Seems there was a ship just about like ours. About three months ago. A mechanic told me about it. Seems they got a new CO assigned to it who was obviously a sickman, just like us. Somebody managed to sneak a few of the dormant spores lying around outside the dome into him. Then the sickman really was sick." I licked my lips. "I didn't mean that," I said. "Besides, they could always tell if you did anything like that." "How?" asked Spender. Harding was listening intently, watching both of us, but he didn't say
