As for Spider, he was not disturbed. A climber from the age of six, he had within him supreme self-confidence. What is distance anyway? If you fall at fifty feet you will die. Can six hundred be worse? Thus he reasoned and, mounting higher and higher, thought only of his goal. He would have a look into that room of mystery. He’d surprise someone at his work and, be he man, woman or devil—flash! There would be a picture.

He was right in part—at least, the flash was not lacking; for, having at last scaled the height, he stood upon a steel cross-beam to draw his chin above a steel window frame. And there he hung, drinking in with his eyes the scene that lay before him.

The right-hand corner of a broad, glass-enclosed space had been roughly partitioned off into a small room. At the center of this narrow space, bending over some curious instrument, was a tall, thin man.

That he was not conscious of prying eyes was at once apparent, for, after a moment, partially straightening up, he switched on a powerful lamp, thus sending a sharp pencil of illumination through the clouds that hung over the city.

This accomplished, he turned half about.

Spider dropped low, he might be seen.

When next he dared bring his eyes above the edge of the window frame he found the man facing a peculiar square of metal attached to a low pedestal.

“A microphone! He’s talking into it. The Whisperer!” Spider breathed.

Then with the force of a blow it came to him that here was his chance.

“The picture,” he muttered low.
