Henry, Jessie, Violet, and Benny used to live alone in a boxcar. Now they have a home with their grandfather, and they are trying to catch a runaway ghost!   When the Aldens visit their friend Fran in Wisconsin, they can't wait to hear her tell the story of the runaway ghost. Fran's family ghost hasn't been spotted in years, but the Aldens still shiver at the spooky tale of the ghost's bell clanging after dark. Then Violet hears a mysterious ringing in the middle of the night, and the children start to wonder—could the runaway ghost be back?
