In a swift rearguard engagement, they fought their way out of the room. Gena's aimed electronic bolt fused the hidden mechanism of the dilating door through which they escaped, momentarily holding up the rush of the hideous crustaceans.

"The tank rooms!" Hammond barked, taking command. "You know how to reach one of them, Gena?"

The girl nodded. Tensed, grim-faced, Hammond followed the girl, keeping Storm and Ardiné between them, electronic rifle held ready.

A small Sediphron squad patrolled the area, evidently on the alert for such a break. But the sudden appearance of the Earthmen and the girls caught them by surprise.

There were eight of them, and four went down to the combined fire of Gena and Hammond before they could train their rifles. Then Storm, laying Ardiné on the hard floor, took a hand.

Only one of that crustacean squad emerged from that withering fire. He succeeded in reaching a huge wall switch. A moment later the huge bell clanged its harsh alarm through the ship.

Hammond killed him, without regret.

They took the nearest war tank, a small, fast scout vehicle. Gena sent it clattering toward the far wall just as Zuggoth and a horde of Sediphrons burst into the room.

The electronic rifle bolts splattered harmlessly against the armor of the speeding tank. Unharmed the fugitives passed through the dilating door, and dipped down the side of the huge space craft.

Hammond hung on to the hand grips, watching Storm. The blond American held Ardiné in the curve of his strong arm, anxiety in his face. Only when the brunette began to stir, open her eyes, did relief finally ease the grimness of Storm's face.
