Why couldn't he perform? Rumors abounded that Frances was slipping him herbs that prevented it. Others stated that he was "bewitched." During the divorce proceedings, it was seriously debated whether he should be sent to Poland to be "unwitched!" Regardless, Carr had the ear of the King. James intervened and the divorce went through.
Curiously, Overbury died in the Tower. The divorce was finalized soon after.
Rumors abounded that Frances had had Overbury poisoned. Despite this, Carr and Frances married in Dec. of 1613. The two were soon arrested on suspicion of murder. Carr proclaimed his innocence. Frances, however, admitted a small part in the crime. She was convicted of murder, but spared execution. Why was the King so lenient? Some think he had a part in the murder, too. He apparently resented Overbury, with one witness saying that James "hath long had a desire to remove him from about [Carr], as thinking it a dishonour to him that the world should have an opinion that [Carr] ruled him and Overbury ruled [Carr]." Both Carr and She were pardoned and finally released from the Tower in 1622. They lived happily together.
With the evidence in, what think ye? Was Frances an innocent woman, whose only crime was to be stuck in a loveless marriage, easily becoming a scapegoat for a jealous King's will? Or was she a loose woman, who would stop at nothing, including murder, to get what she wanted?
