felt his body writhing about, and
experienced pain that was--mortal. A bluish-green light dazzled his
pupils and made him blink.

Something cut into his flesh, and Lambert rolled about, trying to
escape. He bumped into something, something soft; he clung to this
form, and knew that he was holding on to a human being. Then the light
died out, and in its stead was the yellow, normal glow of the electric
lights. Weak, famished, almost dead of thirst, Lambert looked about
him at the familiar sights of his laboratory. He was lying on the
floor, close by the metal plate, and at his side, unconscious but
still alive to judge by her rising and falling breast, was Madge
Crawford.

Someone bent over him, and pressed a glass of water against his lips.
He drank, watching while a mortal whom Lambert at last realized was
Detective Phillips bathed Madge Crawford's temples with water from a
pitcher and forced a little between her pale, drawn lips.

Lambert tried to rise, but he was weak, and required assistance. He
was dazed, still, and they sat him down in a chair and allowed him to

At last, Madge stirred and moaned faintly. They lifted her to a bench,

When she could sit up, she at once cried out for Lambert.

toward her. "Here I am, darling," he said.

"John--we're alive--we're back in the laboratory!"

"Ah, Lambert. Glad to see you." A heavy voice spoke, and Lambert for
the first time noticed the black-clad figure which stood to one side,
near the switchboard, hidden by a large piece of apparatus.

"Dr. Morgan!" cried Lambert.

Althaus Morgan, the renowned physicist, came forward calmly, with
outstretched hand. "So, you realized your great ambition, eh?" he said
curiously. "But where would you be if I had not been able to bring you
back?"

"In Hell--or Hell's Dimension, anyway," said Lambert.

He went to Madge, took her in his arms. "Darling, we are safe. Morgan
has managed to re-materialize us. We will never again be cast into the
void in this way. I shall destroy the apparatus and my notes."

Doherty, who had been out of the room on some errand, came into the
