The Parasite

The Parasite by Ramsey Campbell. paperback edition. ISBN: 9780671419059.

It began with a little game...

...for children to amuse and frighten each other. A seance. In a dark, empty house. Dont tell the grown-ups.

But something unexpected happened that night. Some awful evil awoke in the foul dampness, something each child sensed, and fled from...

All but one.

Poor little Rose, shrieking her terror in that attic room, as some quivering form approached.

Poor little Rose, unspeakably invaded.
