Transports from powerful and peaceful Alpha Centauri moved with extra convoys, ready for instant action. No one knew when the Phantom would strike. No one knew from what planet it came to attack like a black meteor without warning. Yet Standish challenged no ship but those of Sirius. Haunting the lanes between Sirius and Earth, he seized enemy prison ships and troop transports alike with daring regularity. The city of Calthedra was filled to overflowing with Sirian prisoners. But the man Standish wanted most, Drum Faggard, was never on a captured ship. Desire to capture Faggard became almost an obsession as the Earthman went on. Through the powerful radio which he had built on Lyra, he learned of the situation on Earth, day by day. The news was black.

"You've done all one person possibly could do." "I need an army and a fleet," Standish said. "Yet on all Lyra
