On the suggestion of the young friends first met on the night of. . . the Halloween Handout (p. 222, J-54), Schulman's dopey Jack the Bum moves into a haunted house to find shelter as winter approaches. But on the first night Jack discovers that the ghost roommate he had innocently expected is really Jules the jewel thief, stashing a huge haul. The police commend Jack for catching the thief but kick him out regardless (""Our town law is 'No bums allowed'""); once more to the rescue, the children catch him up on the highway out of town and introduce him to the haunted house's owner, who needs a night watchman. It's a characteristically mild compromise--Jack's status as a bum remains intact, as a watchman doesn't have to do anything. But perhaps that's what makes Jack as a character a bit slack.
