The day after, she was given permission by the king to be placed in safe custody at Vaxholm Castle. She demanded a court to investigate her involvement in the death of the crown prince. She remained at Vaxholm until November, when she was cleared from all charges. During the investigation, she received several proposals of marriage, one from Georg Carl von Döbeln: she did not accept, but it led to a correspondence between them. Sophie was described as a charming beauty but was also feared for her ambition and sharp tongue.
