CAGED IN HIS NAME
Marc travelled to Madagascar in 2018 to report on the women being jailed for crimes their male relatives are accused of.
Reporting for the BBC World Service, Marc spoke to women who have been detained for months – and sometimes years – told they were "accomplices" or should have known what their husbands, brothers or sons were doing. Many have been held for years in detention for years without trial for crimes including the rape of a nun.
Here are a selection of photographs from the project.
