I was not garbed like the others. They could move out on the wing runway under Hanley's eyes at short range, or climb in and out of the balloon car, and not be visible.

Gutierrez brought the sack. A dead-black fabric.

"Shall I cut him loose now from his chair, Commander?"

"I'll do it."

De Boer drew a long knife blade, coated black, and thin and sharp as a half-length rapier. Gutierrez had one of similar fashion. No electronic weapons were in evidence, probably because the hiss of one fired would have been too loud for our barrage, and its flash too bright. But a knife thrust is dark and silent!

The Spaniard's eyes were gleaming as he approached me with the bag, as though he were thinking of that silent knife thrust he would give me at the last.

Dr. Boer said, "Stand up, Grant." He cut the fastenings that held me in my chair. But my ankles and wrists remained tied.

"Stand up, can't you?"

"Yes."
