Then for another hour he sat alone in the darkness of his room, watchful and patient. He drew up the curtain toward Alma's room. There was a light there, and he sat gazing at her white curtain till the light was extinguished. The other lights were all put out one after the other, and then it became very still.
The clock struck ten. The gathering storm climbed higher up the western sky. The lightning flashed brighter and brighter. There was a sigh in the tree tops as if the air stirred uneasily.
Suddenly there was another light. Mr. Belford's curtain was brightly illuminated by his candle. Elmer moved his chair so that he could watch the window, and waited patiently till the light was put out. Then he saw the curtain raised and the window drawn down.
"All right, my boy! That's just what I wanted. Nemesis has a clear road, and her shadowy sword shall reach you. Now for the closed circuit alarm."
He silently pulled off his shoes, and then, with the tread of a cat, he felt about his room till he found on the table two delicate coils of fine insulated wire, and a couple of tacks. Carefully opening the door, he crept down stairs and through the hall to the door of the library. The door was closed, and kneeling down on the mat he pushed a tack into the door near the jamb and stuck the other in the door post. From one to another he stretched a bit of insulated wire. Then, aided by the glare of the flashes of lightning, that had now grown bright and frequent, he laid the wires under the mat and along the floor to the foot of the stairs. Then in his stockinged feet he crept upward, dropping the wires over into the well of the stairway as he went. In a moment or two the wires were traced along the floor of the upper entry and under the door into his room. Here they were secured to a small battery, and connected with a tiny electric bell that stood on the mantle shelf. To stifle its sound in case it rang, he threw his straw hat over the bell, and then he felt sure that at least one part of his work was done.
Louder and louder rolled the thunder. The lightning flashed brightly and lit up the bare, mean little room where the wretch cowered and shivered in the bed, sleepless and fearful he knew not why. He feared the storm and the night. He feared everything. His guilty heart made terrors out of the night and nature's healthful workings. The very storm, blessed harbinger of clearer days and sweeter airs, terrified him.
There was a sound of rushing wind in the air. A more vivid flash blinded him. He sat up in bed and stopped his coward ears to drown the splendid roll of the thunder. Another flash seemed to fill the room.
Ah! What was that? His eyes seemed to start from their sockets in terror.
There, written in gigantic letters of fire upon the wall, glowed and burned a single word:
FRAUD!
