What terrors were performed in Labatory One,that its vry name could cause strong men and innocent children to tremble with fear? Only the Master knew that it was not terrorthat was housed behind those impregnable walls but the most precious secret of the ages---the secret of immortality. The safety of all humanity lay in the Master's silence--yet the life of the one woman he loved hung in the balance. He could buy a new lease on her precious life at the price of the world's security. Only a god can resist temptation--and the Master, though he had lived a thousand years, was still a man.
