"Science fiction writers foresee the inevitable, and although problems and catastrophes may be inevitable, solutions are not."
- Isaac Asimov

His left hand reached into a side pocket, touched a flat oval device, smaller than his palm and pressed a stud. A mechanism began to purr. It was a pocket-caller, tuned to beams of certain other devices of the same sort.
