"What of the Martians?"

I shrugged. "We've made enemies of the Martians by killing two of them. I doubt if they'll forgive us for that. They've shown too many human qualities—curiosity, fear, bravado, for example. They probably have the ability to be angry and to extract an eye for an eye. So we're fighting a whole planet. Whether there are five of us or three wouldn't make much difference. But Spartan has us prepared for a lift-off and I don't think he intends to wait for an attack to trim down our numbers."

She looked thoughtful, then said, "Bill, are you suggesting we murder Dr. Spartan?"

I hadn't suggested it. All I was thinking of was saving my life and hers. Self-protection. But that included killing in self-defense. Possibly I'd had murder in the back of my mind. But when she said it in so many words, I was revolted.

"Not if we can avoid it," I said.

"But there isn't enough water for five, you said. That means—" She stopped.

"I'm willing to try it on rations," I said. And I was. "Spartan isn't. Spartan planned to get rid of us anyhow."

Slowly she shook her head. "No, I don't believe even Spartan could be like that. I'll admit I did think it once. But he'd have too much to explain when he got home. Still, if he could arrange an accident—"

"He's arranged two of them. Willy and Morrie. What's to stop him from getting rid of Axel and me? Perhaps you, if you were likely to be a witness against him."

"We can't be a party to murder, Bill Drake," she said.
