She raised one hand and flexed its fingers and wondered$$$ as she had sometimes before$$$ how this thing$$$ this machine for gripping$$$ this fleshy spider on the end of her arm$$$ came to be hers$$$ entirely at her command. Or did it have some little life of its own? She bent her finger and straightened it. The mystery was in the instant before it moved$$$ the dividing moment between not moving and moving$$$ when her intention took effect. It was like a wave breaking. If she could only find herself at the crest$$$ she thought$$$ she might find the secret of herself$$$ that part of her that was really in charge.
