She was killing him as Jack killed her. He drove the living blade into the lower rounded surface of her belly, piercing her sex organs as she rode astride the old man. She decamped blood and viscous fluids over the prostrate body of the old man, who also died, for Jack’s blade had severed the penis within the young woman. She fell forward across the old man and Jack left them that way, joined in the final embrace.

He found a man and throttled him with his bare hands, even as the man tried to dematerialize. Then Jack recognized him as one of the phlox, and made neat incisions in the face, into which he inserted the man’s genitals.

He found another woman as she was singing a gentle song about eggs to a group of children. He opened her throat and severed the strings hanging inside. He let the vocal cords drop onto her chest. But he did not touch the children, who watched it all avidly. He liked children.

He prowled through the unending night making a grotesque collection of hearts, which he cut out of one, three, nine people. And when he had a dozen, he took them and laid them as road markers on one of the wide boulevards that never were used by vehicles, for the people of this City had no need of vehicles.

Oddly, the City did not clean up the hearts. Nor were the people vanishing any longer. He was able to move with relative impunity, hiding only when he saw large groups that might be searching for him. But something was happening in the City. (Once, he heard the peculiar sound of metal grating on metal, the shrikkk of plastic cutting into plastic—though he could not have identified it as plastic—and he instinctively knew it was the sound of a machine malfunctioning.)

He found a woman bathing, and tied her up with strips of his own garments, and cut off her legs at the knees and left her still sitting up in the swirling crimson bath, screaming as she bled away her life. The legs he took with him.
