[4] Upon author Jack Vance's death in 2013, after rights revisions, Bad Ronald (which by the 2000s had long-since fallen out of print and was considered rare to collectors and readers) was republished as an eBook and a print on demand paperback by publisher Spatterlight Press.

Having forgotten his jacket at the scene of the crime, he confesses to his mother, who decides to hide Ronald in their house.

When his mother dies, a couple and their three daughters move into the house, none-the-wiser that Ronald is living in the walls.
