It's been two weeks of unrelenting New York City summer heat. Sooner or later the boys are apt to get into mischief, so Knuckles takes the load of 'em to Algy's father's camp in the mountains. The trip gets sidetracked when they cross paths with Judge Parker's party on the road. The Judge, hiding from the mob, is desperately heading to his mountain manor when he runs the boys' vehicle off the road, nearly disabling it right before his own car conks out. With only the boys' car barely able to travel, they all wind up at the judge's manor where ghostly sightings, spooky organ music, death threats and a creepy housekeeper await them. Judge Parker is the very judge who once nearly put Knuckles on death row for murder. When the judge turns up dead, Knuckles is in trouble again, with little brother Danny and the gang ready to help him out.
