"You did not see it?" replied Dr. Pye.

"See what?"

"The figure of Samuel Boyd standing at his window?"

Dr. Vinsen stared incredulously at his host, and then a long deep breath of relief escaped him. "Only that!" he exclaimed. "I thought it was something worse."

Dr. Pye repeated his question. "You did not see it?"

"I saw nothing. The dead do not rise from their graves. Dead once, dead for ever. But you can convince me by producing ocular proof. Your ingenious device takes an instantaneous picture of any object upon which it flashes its light. Produce me the picture of the dead and buried Samuel Boyd."

"I cannot. The last film has been used, and I omitted to put in others."

"Very unfortunate," said Dr. Vinsen, dryly. "Suppose you supply the omission, and try again."

Dr. Pye acted upon the suggestion. He placed an automatic arrangement of films in the little machine, again turned down the gas, again opened the circular lid in the shutter, again threw the flash light upon the house of Samuel Boyd. The blank walls and windows confronted them, and no sign of life, physical or spiritual, was visible; and when the film was removed and developed it showed no face of man or spirit.

"I did not expect a result," said Dr. Pye; "there was no form at the window."
