saw no light, convinced
against his will, or rather, against his scientific conviction, that she
was not wholly mistaken.

"Still," he observed triumphantly, "your vampires suck blood; but
Reginald, if vampire he be, preys upon the soul. How can a man suck
from another man's brain a thing as intangible, as quintessential as
thought?"

"Ah," she replied, "you forget, thought is more real than blood!"

Only three hours had passed since Ethel had startled Ernest from his
sombre reveries, but within this brief space their love had matured as
if each hour had been a year. The pallor had vanished from his cheeks
and the restiveness from his eyes. The intoxication of her presence had
rekindled the light of his countenance and given him strength to combat
the mighty forces embodied in Reginald Clarke. The child in him had made

"What are you planning to do?"

"My play--I am sure now that it is mine--I cannot take from him; that is
irretrievably lost. He has read it to his circle and prepared for its
publication. And, no matter how firmly convinced you or I may be of his
strange power, no one would believe our testimony. They would pronounce
us mad. Perhaps we _are_ mad!"

"No; we are not mad; but it is mad for you to stay here," she asserted.

"I shall not stay here one minute longer than is absolutely essential.
Within a week I shall have conclusive proof of his guilt or innocence."

"How will you go about it?"
