Some years after Christine and Léa started working for the family, Madame Léonie developed depression. She deteriorated, not handling her struggles well; targeting of the Papins developed as her unhealthy coping mechanism.[citation needed] She began to scrutinize the cleaning, becoming critical of the quality of the job being done.[citation needed] There were various occasions of Madame Lancelin reportedly physically assaulting the sisters.[citation needed] The abuse worsened: at its peak she would slam the sisters' heads against the wall.[citation needed]
