Metal screeched a protest. The seat rocked violently.

Ross wrenched again.

A contact-point snapped. Connections tore loose. Sideslipping, out of control, the seat careened down to a precarious landing athwart the catwalk.

Convulsively, Mawson beat at Ross' face—raking the cheeks, stabbing for the eyes.

Ducking his head, Ross levered the control-arm still farther out of place.

A sound close to that of a sob echoed in Mawson's throat. He pounded Ross' back. "Stop it, you fool! Stop it, before you kill us both!"

Panting with strain, Ross paused for an instant.

Mawson, babbling: "Don't you see? There's no way left for us to get out of here except that skylight—and it's too high to do us any good without the grav-seat."

A small, spasmodic ripple of movement, like the passing of a chill, crossed Ross' shoulders. He still didn't speak.

"Turn me in to FedGov Security if you want to, rack you!" raged Mawson. "Do you think I care about that? Just get us out of this hell-hole alive; that's all I ask!"
