Alibi for a Witch

If Lester Ballard had any say in the matter, he wouldn't be dead in the cheap gabardine suit. Ruth Seabright, governess to Lester's son Nicky, found his murdered body, & was as baffled by its incongruous attire as by the murder itself. But that is only the first of many puzzles: where is Nicky, who has been searching Ruth's bedroom, & how can a corpse be in two places at once?
