her, attached it by means of a coil of wire to the battery, and with firm,
soft fingers slipped it on to Lenora's forehead. Then he stepped back. A
rare emotion quivered in his tone.

"She's a subject, Laura--I'm sure of it! Now for our great experiment!"

They watched Lenora intently. Her face twitched uneasily, but she did not
open her eyes and her breathing continued regular. Quest bent over her.

"Lenora," he said, slowly and firmly, "your mind is full of one subject.
You see your mistress in her chair by the fireside. She is toying with her
diamonds. Look again. She lies there dead! Who was it entered the room,
Lenora? Look! Look! Gaze into that mirror. What do you see there?"

The girl's eyes had opened. They were fixed now upon the
mirror--distended, full of unholy things. Quest wiped a drop of
perspiration from his forehead.

"Try harder, Lenora," he muttered, his own breath labouring. "It is there
in your brain! Look!"

Laura for the first time showed signs of emotion. She pointed towards the
mirror. Quest was suddenly silent. He seemed to have turned into a figure
of stone. For a single second the smooth surface of the mirror was
obscured. A room crept dimly like a picture into being, a fire upon the
hearth, a girl leaning back in her chair. A door in the background opened.
A man stole out. He crept nearer to the girl--his eyes fixed upon the
diamonds, a thin, silken cord twisted round his wrist. Suddenly she saw
him--too late! His hand was upon her lips,--his face seemed to start
almost from the mirror--then blackness!
