For years, the top secret British government organization SOE Q,
informally know as the Laundry, has guarded mankind from paranormal
threats from our own universe and beyond.

The existence of the sentient subaquatic species, codename Poseidon
Alpha, has been kept a carefully guarded secret from the public and
from all but a select few of the world's governments. A centuries-old
noninterference treaty with the sea-dwellers is about to expire,
however, and a rival species, codename Varuna Nine, has suddenly made
its presence known as well, demanding a role in the negotiations.
   
Top agents and representatives of SOE Q have been summoned to the
hidden seaside town of Dunwich, to negotiate new treaties. Something
else is going on, too, though -- base computer stations have been
shutting down mysteriously, and there have been rumors of demons being
sighted in abandoned corners of the base...
