The major nodded gravely. "I understand," he said. "You may rest assured no one will interfere with your men!"

"Huh!" sneered Coxine. "You don't sound so high and mighty now that you're staring into the barrels of a dozen atomic blasters!" He snapped off the teleceiver and roared with laughter.

Tom felt a shiver run down his spine. He could imagine the frustration of the Ganymede garrison, a crack crew of fighting men, forced to surrender without firing a shot. And he had been the cause by giving Coxine the code recognition signal!

Coxine snapped an order into the intercom and a moment later Tom saw the jet boats on the scanner, rocketing down to the surface of the small satellite.

As, one by one, the small ships landed on the spaceport, the three cadets could see the crowds of colonists fan out, allowing the jet boats to come in without interference.

Coxine strode up and down the control deck restlessly, but keeping his eyes on the activity below. Suddenly he rushed to the scanner, stared hard, and then let out a roar of triumph.

The three cadets saw the reason immediately. On the scanner were the unmistakable outlines of two Solar Guard heavy cruisers, four destroyers, and six scouts, hurtling spaceward at tremendous speed. Coxine spun around, balled his fists into tight knots, and shook them at the three cadets.

"I've won! I've won!" He roared with insane laughter and there was a crazed gleam in his eyes. "I've got the ships, the guns, the men, and the secret of the adjustable light-key. By the time I'm finished with the Solar Guard there won't be anything left of those crawlers but what you can hear on a story spool, and the Solar Alliance will be run by one man!" He paused, his face grew hard and he tapped his chest menacingly. "Me!"
