“Tower Number Two. Briggs on duty. All O. K.” came the report over the wire.
Then came New Tower Number Three; next Tower Number Four. From the three outside guard-posts came the reports, and one from the cell house, each guard turning in his post number, his name and the usual “O. K.”
All the indicators on the board, except that for Old Tower Number Three, were now turned. Captain Dunlap relaxed in his chair, sighed heavily and lit his pipe. Lazily his eyes wandered back to the indicator board.
The unturned indicator for Old Tower Number Three held his gaze and utter sadness gripped him for a moment. Night after night, promptly on the hour, he had seen the indicator for Old Tower Number Three flip jauntily to the left and had heard the tinkle of the little bell on the board. It had always seemed to him that the indicator for Asa Shores’ tower turned with more pep than the other indicators, that the bell had tinkled more cheerily, that good old Asa Shores’ report carried a note of cheerfulness that lightened the lonesome watches of the night.
Now the old tower was cold, even as poor old Asa was cold; the doors were locked and barred. Never again, thought Dunlap, would be heard Asa Shores’ familiar song on the quiet night air. What were the words to that song?
“When I am dead and buried deep,
“I’ll return at night to take a peep
“At those who hated—”
Captain Dunlap suddenly sat erect in his chair. The pipe fell from his lips and clattered on the floor, as his lower jaw dropped and his eyes opened wide to stare at the indicator board; for—
The indicator for Old Tower Number Three was moving—moving, not with a quick turn to the left, but in a hesitant, jerky way that caused the root of every hair on Captain Dunlap’s head to tingle. Never before had the captain seen an indicator behave like that. In fact, the indicator system was designed and constructed in such a way that, being controlled by electric contacts, the various indicators would snap into position when a push button in each tower was pressed by the guard on duty in that tower.
In short, an indicator, in accordance with all the rules of electricity as applied to the system, must remain stationary or jerk to the left when the button in the tower was pressed. But here was indicator for Old Tower Number Three wavering, trembling to the left, only to fall back repeatedly to a vertical position. Then again, jerkily, hesitantly to the left, as if a vagrant soul strove to brush aside the veil that banished it from the living.
Captain Dunlap sat rigid and watched the uncanny movements of the bright brass indicator. Vague, fleeting, chaotic thoughts of crossed wires, practical jokers, wandering souls tumbled one after another through his brain.
