It was a silly and careless way of doing things, he inwardly decided, this lazy stringing of wires from house-top to house-top, instead of keeping them in the tunnels where they belonged. It was not only violating regulations, but it was putting a premium on “lightning-slinging.” And he remembered what Frances had once said to him about criminals in a city like New York, how the careless riot of wealth seemed to breed them, as any uncleanness breeds bacteria; how, in a way, each was only a natural and inevitable agent, taking advantage of organic waste, seizing on the unguarded and the unorderly. She had even once argued that the criminal could lay claim to a distinct economic value, enjoining, as he did, continual alertness of attention and cleanliness of commercial method. Yet the devil himself, he had somewhere read, could quote Scripture for his purpose; and his fishing-pole moved restlessly up and down, like a long finger feeling through answering strings. For each time, almost, that his hook rested on one of the wires the little Bunnell relay on the table behind him spoke out feebly. To the trill and clatter of these metallic pulsations Durkin listened intently, until, determining that he had looped into the right wire, he made secure his switch and carefully drew down the window to within an inch of the sill. Then he gave his studious attention to the little Bunnell relay. Its action was feeble and spasmodic. It was doing scant justice to what Durkin easily saw was a master-hand toying with the rubber button at the far-distant end of the wire. It was not unusually quick operating, but, as the dots and dashes flew on and on, the interloper for a moment or two forgot the meaning of the messages in the clear-cut, crisp, and precise beauty of the sender’s Morse. “That man,” commented the admiring craftsman in Durkin, “is earning his eight dollars an hour!” Then, adjusting his rheostat, he slowly and cautiously graduated his current, until new life seemed to throb and flow through the busy little piece of clicking metal. A moment later it was speaking out its weighty and secret messages, innocently, authoritatively, almost triumphantly, it seemed to the eavesdropper, bending over the glimmering armature lever. A quietly predaceous smile broadened on Durkin’s intent face. He suddenly smote the table with an impetuous little rap of the knuckles, as he sat there listening. “By heaven, this _will_ open her eyes!” he cried, under his breath. And he repeated the words more abstractedly, as he lifted his telephone transmitter out on the table and threw open a switch on the wall, well-concealed by the window curtain.
