Far, far away from planet Earth, at a dull, unappealing star, a single planet sits in orbit. A synthetic planet, constructed entirely from metal and concrete and computers, aimlessly moving through space. Filled with empty rooms and silent corridors, this planet lies abandoned by its creators but not by their creations. An echo of a whirring saw cuts through the silence of this dead computer planet with malice.
Deep down, on the 135th floor, a distorted scream shouts out to nobody before silence once again reclaims the air. The scream, the saw, both die into faded echoes, followed only by one heavy, deafening clang. It resonates through the planet like a gong for more than five minutes and somewhere, in a pitch-black room, a soft whimpering sound can be heard, not unlike that of a young girl. Trying its best to stay quiet, the voice pants in short stutters before whispering slowly and almost unheard.
"P-p-please…save…me." The cry falls silent as the last echo of the clang fades away. Then silence. The planet is dead and lifeless once more. Then, a new sound. Something completely and utterly new. Unrecognisable and entirely unheard of before and almost impossible to describe.
"It's like the wind…" Thought the child. "No, more like a siren. Or a whistle. Now it's screeching and reverberating. What could it be?" And then it stopped with a short clang but unlike the other, this one did not fill her with feelings of dread but somehow it was almost comforting. Like her prayers had been answered.

Up, way up, on the surface of the planet, something rather odd had appeared. On this abandoned hunk of metal, way out in the unwanted reaches of space, a blue box now stood proudly, warm lights shining from within and reflecting colour upon the metal floor below. Words from an ancient Earth language are written in glowing writing above what seems to be a door. "Police Public Call Box".
