The photograph studio of Blinky Collins was on the third floor of a disreputable building in an equally unsavory part of Chicago. There were no tinted pictures of beautiful blondes nor of stern, square-jawed men of affairs in Blinky’s reception room. His clients, who came furtively there, were strongly opposed to having their pictures taken—they came for other purposes. For the photographic work of Mr. Collins was strictly commercial—and peculiar. There were fingerprints to be photographed and identified for purpose of private revenge, photographs of people to be merged and repictured in compromising closeness for reasons of blackmail. And even X-Ray photography was included in the scope of his work.
The great discovery came when a box was brought to the dingy room and Mr. Collins was asked to show what was inside it without the bother and inconvenience of disturbing lock and seals. The X-Ray machine sizzled above it, and a photographic plate below was developed to show a string of round discs that could easily have been pearls.
The temporary possessor of the box was pleased with the result—but Blinky was puzzled. For the developer had brought out an odd result. There were the pearls as expected, but, too, there was a small picture superimposed—a picture of a bald head and a body beneath seated beside a desk. The picture had been taken from above looking straight down, and head and desk were familiar.
Blinky knew them both. The odd part was that he knew also that both of them were at that instant on the ground floor of the same disreputable building, directly under and two floors below his workshop.
Like many great discoveries, this of Blinky’s came as the result of an accident. He had monkeyed with the X-Ray generator and had made certain substitutions. And here was the result—a bald head and a desk, photographed plainly through two heavy wood floors. Blinky scratched his own head in deep thought. And then he repeated the operation.
This time there was a blonde head close to the bald one, and two people were close to the desk and to each other. Blinky knew then that there were financial possibilities in this new line of portrait work.
It was some time before the rat eyes of the inventor were able to see exactly what they wanted through this strange device, but Blinky learned. And he fitted a telescope back of the ray and found that he could look along it and see as if through a great funnel what was transpiring blocks and blocks away; he looked where he would, and brick walls or stone were like glass when the new ray struck through them.
Blinky never knew what he had—never dreamed of the tremendous potentialities in his oscillating ethereal ray that had a range and penetration beyond anything known. But he knew, in a vague way, that this ray was a channel for light waves to follow, and he learned that he could vary the range of the ray and that whatever light was shown at the end of that range came to him as clear and distinct as if he were there in the room.
He sat for hours, staring through the telescope. He would train the device upon a building across the street, then cut down the current until the unseen vibration penetrated inside the building. If there was nothing there of interest he would gradually increase the power, and the ray would extend out and still out into other rooms and beyond them to still others. Blinky had a lot of fun, but he never forgot the practical application of the device—practical, that is, from the distorted viewpoint of a warped mind.
