Martin writes from Barrandov, Prague. Martin complains that he can no longer remain silent about the impertinent letter he received from his son Klaus, who is in Hilterfingen, Switzerland. Martin complains that Klaus had in the past harbored negative feelings about Martin and his work, but has since made them open. Martin vows to deal with this problem while acting in the interest of the whole family. He writes that Klaus spends his money recklessly and cavorts with young women in their rooms. Martin avers that if Klaus continues to act this way, he should be made to fend for himself. Martin ends by exhorting his wife to use a strong hand to bring the boy back in line.
