Other uniformed men—hands of the Terrestrial Space Fleet—were coming into view from among the boughs. They, too, were armed. Ling walked across to Parr, a struggling captive under each arm.

"What are these strangers up to, boss?" he demanded. "Say the word and I'll wring that officer's neck. I never liked officers, anyway."

"Wait," Parr bade him. Then, to the man called Captain Worrall: "Just what are you doing here?"

"This asteroid," replied Worrall, "is now Terrestrial territory. We're fortifying it against the Martians. War was declared three weeks ago, and we made rocket-tracks for this little crumb. It's an ideal base for a flanking attack."

Parr scowled. "You're fortifying?" he repeated. "Well, you'd better shag out of here. There's a power—not working just now, but—"

"No fear of that," Varina Pemberton told him. She was smiling.

"I can explain best by starting at the start. Recently we got a report of what the Martians were doing out here. We realized that Earth must take care of her own, these poor devils who were being pushed back into animalism. Also, with war inevitable—"

"You aren't starting at the start," objected Parr. "Where do you fit into all this? You're no soldier."

"Oh, but she is," Captain Worrall said, offering Parr a cigarette from a platinum case. "She's a colonel of intelligence—high ranking. Wonderful job you've done, Colonel Pemberton."
