"Good," I said.

But the thought of hurling our bolts at this enemy ship had struck terror into my heart for hours past. I was convinced that the three who in all the world were dearest to me—Anita, Venza, and Snap—were upon that enemy vessel.

Grantline asked, "Are you going closer to the Moon?"

"No."

"The ship couldn't be between us and the Moon. Waters and I have been in the helio room for the past hour, searching with the 'scope there. Nothing doing, Gregg. Not a sign."

"I know. Our instruments here show that."

"There might be a way of sighting them," Drac put in.

"I'll try the Zed-ray," I suggested. "Drac and I have it corrected. But I doubt if it would penetrate the sort of invisibility this enemy would use."

Grantline nodded. "Or the Benson curve-light. You think the ship went behind the Moon? Or landed on the Moon?"

"It could have done either. Has Waters still got contact with the Earth? Have they seen it?"
