Is Percy tårar coming back?

Percy Nilegård has gone to see a psychologist; Dr J. Tull, which may not be his real name, and reveals how he took over another person's life to make money. Percy feels lonely and wants Dr. Tull to help him write his memoir. Their conversation then shifts to a series of flashbacks in which Percy relates the story of how he exploited the new boss of an old family-run brewery.
