Publisher's Summary

The story concerns an abandoned truck owned by Otto Schenck and George McCutcheon, wealthy Castle Rock businessmen in the post-depression era. After Otto deliberately crushes George beneath his derelict vehicle, the murderer becomes fixated on the truck. Otto insists that the truck is not only moving on its own accord, but planning to kill him. At the same time, he becomes a social recluse, living in a house he built across from the truck itself, and generally begins to lose his sanity. His nephew, who tells the story, finally finds him dead–the corpse has been drowned with oil and there is a spark plug rammed down his throat.
