Carolina Rediviva (1920)

'Pojken' has been a student in Uppsala for many, many years. Many years ago he found a baby girl outside the fraternity house during a party. Pojken made sure that the girl could grow up in the countryside and has ever since sent money to the foster mother. Now the girl, Carolina, has moved back to Uppsala and is living with her real mother, who married nutty professor Hambreus. Carolina knows nothing about Pojken or the money he has sent, but now he has decided to reveal the truth to her.
