it, for you believe that in another life you shall
step into Time, or, as you call it, eternity." She leaned closer so that
her hair brushed his cheek. "What is eternity, John Northwood? Is it not
keeping forever ahead of the Destroyer? The future is eternal, for it is
never reached. Adam and I, through our new sense which comprehends Time
and Space, can vanish by stepping a few seconds into the future, the
Fourth Dimension of Space. Death can never reach us, not even accidental
death, unless that which causes death could also slip into the future,
which is not yet possible."

"But if the Fourth Dimension is future Time, why can one in the third
dimension feel the touch of an unseen presence in the Fourth
Dimension--hear his voice, even?"

"Thought vibration. The touch is not really felt nor the voice heard:
they are only imagined. The radioactive waves of the brain of even you
Black Age people are swift enough to bridge Space and Time. And it is

Her red mouth reached closer to him, her blue eyes touched hidden forces
that slept in remote cells of his being. "You are going into Eternal

For a split second he felt the sweet pressure of baby-soft lips, and
then the atoms of his body seemed to fly asunder. Black chaos held him
for a frightful moment before he felt sanity return.

He was back on the terrace again, with Eve by his side. They were
standing now. The world about him looked the same, yet there was a
subtle change in everything.

Eve laughed softly. "It is puzzling, isn't it? You're seeing everything
as in a mirror. What was left before is now right. Only you and I are
real. All else is but a vision, a dream. For now you and I are existing
one minute in future time, or, more simply, we are in the Fourth
Dimension. To everything in the third dimension, we are invisible. Let
me show you that Dr. Mundson cannot see you."

They went back to the room beyond the terrace. Dr. Mundson was not
present.

"There he goes down the jungle path," said Eve, looking out a window.
She laughed. "Poor old fellow. The children of his genius are worrying
