pound of Martian radium aboard.”

“A pound!”

“A hell of a lot, even considering the big radium deposits on Mars. With my connections, I can sell the stuff. You’re going to hijack the Maid of Mercury, Duncan, and get that radium.”

“Hijacking a spaceship? It’s crazy.”

“It’s never been done, sure. Nobody’s dared go into space without a Helmet. And the government issues the Helmets. But look at the other side of it. We’ve got a few patrol boats—the Interplanetary Police. Which is a loud, raucous laugh. Rickety tubs with no real armament. You won’t have to worry about them.”

“Hartman will explain—the man we’re going to see now. Take my word for it that you can go into space without a Helmet and be safe. Fairly safe.”

“Half a million credits—”

“The only danger,” Olcott said carefully, “is that the Maid might send out an S.O.S. The I.P. ships are rickety, but they’re fast, and they might stay on your trail. We can’t have that. So we’ve planted somebody on the Maid who’ll smash the radio apparatus just before you make contact. You can pick her up with the radium and head back to Earth.”

“Her?”

“You know her, I think,” Olcott said quietly, his eyes impassive. “Andrea Duncan.”

Duncan moved fast, but there was a gun in Olcott’s hand covering him.

The latter said, “Take it easy. You killed one man with your fists. I’m taking no chances.”

A tiny scar on Duncan’s forehead flamed red. “You rotten—”

“Don’t be a fool. She’s wearing a Varra Helmet. Of course she’ll take it off when she joins you, or she’d have a Varra en rapport with her, one who’d spill the beans completely.”

“Andrea wouldn’t—”

“She doesn’t know all of my plans. And she was willing to help me—as the price of your freedom. Listen!” Olcott spoke persuasively. “The girl’s already on the ship. She’s got her instructions. Tomorrow, at three P.M., she’ll smash the radio. If you’re not on hand to pick her up—and the
