As every secret policeman knows, there is no such thing as a coincidence; the state has too many enemies. - Charles Stross

The first rule of space travel...is that mistakes are fatal. Space isn’t friendly; it kills you. And there are no second chances.”

The Laundry is the British Government’s secret agency for dealing with “magic.” The use of scare-quotes is deliberate; as Sir Arthur C. Clarke said, “Any sufficiently advanced technology is indistinguishable from magic,” so “magic” is what we deal with. Note that this does not involve potions, pentacles, prayers, eldritch chanting, dressing up in robes and pointy hats, or most (but not all) of the stuff associated with the term in the public mind. No, our magic is computational. The realm of pure mathematics is very real indeed, and the...things...that cast shadows on the walls of Plato’s cave can sometimes be made to listen and pay attention if you point a loaded theorem at them. This is, however, a very dangerous process, because most of the shadow-casters are unclear on the distinction between pay attention and free buffet lunch here. My job—applied computational demonologist—comes with a very generous pension scheme, because most of us don’t survive to claim it.

One of the great besetting problems of the modern age is what to do with too much information.
