slid the bag from my face. I feared an abrupt alarm, or Gutierrez leaping upon me. But there was silence, and I saw his vague dark outlines at the window oval, five feet from me.

I got my ankles loose and slid the bag off. I was unsteady on my feet, but desperation aided me.

Gutierrez half turned as I gripped him from behind. My hand on his mouth stifled his outcry. His black knife blade waved blindly. Then my clenched knuckle caught his temple, and dug with the twisting Santus blow. I was expert at it, and I found the vulnerable spot.

He crumpled in my grasp, and I slid his falling body across the narrow corridor into the nearest cubby oval.

Almost soundless; and in the control room Jetta and De Boer were murmuring and gazing at Hanley's ship, which hung ahead and above us at the zero-height.

I had planned all my movements. No motion was lost. Gutierrez was about my height and build. I stripped his black suit from him, donned it, then tied his ankles and wrists, and gagged him against the time when he would recover consciousness. Then I stuffed his body in the sack and tied its top.

This black suit had a mask, rolled up and fastened to the helmet. I loosed it, dropping it over my face. Knife in hand, I stood at the corridor window.
