But Krobis spun aside, not even attempting to flee; he snatched up the fallen guard's nerve-gun.

Then, pivoting, ignoring the monster, he aimed the gun straight at Lor's prone figure.

Eyes open now, the mutant jerked back—trapped, cornered.

Boone and Eileen lunged as one.

The girl was closest. Her hand hit the nerve-gun as Krobis pulled the trigger.

The charge burned out against the wall-plates off to one side of Lor.

Before Krobis could fire again, Boone was upon him. They went down together, rolling and wrestling and panting. Boone could feel his strength begin to go.

But now it was not for himself that he was fighting. The fate of two races hung on the outcome.

With a curse, he writhed suddenly upward, then threw himself back, smashing Krobis' head down to the floor.

The other's muscles went slack. Sobbing, Boone kicked clear.
