 Charles VI died in October 1422 . As Henry V had died earlier the same year , his infant son by Catherine , Henry VI , was proclaimed King of France , according to the terms of the Treaty of Troyes , with the Duke of Bedford acting as regent . Rumors circulated about Isabeau again ; some chronicles describe her living in a " degraded state " . According to Tuchman , Isabeau had a farmhouse built in St. Ouen where she looked after livestock , and in her later years , during a lucid episode , Charles arrested one of her lovers whom he tortured , then drowned in the Seine . Desmond Seward writes it was the disinherited Dauphin who had the man killed . Described as a former lover of Isabeau as well as a " poisoner and wife @-@ murderer " , Charles kept him as a favorite at his court until ordering his drowning .
