In 1852, Sarah Maria Louisa Kirwan was found dead at the Long Hole on Ireland’s Eye as the tide receded. Her husband, William, had been painting a sunset scene of the Dublin Mountains and told the boatmen who returned to get them from the craggy island in Dublin Bay that he had no idea what had happened to her. An inquest found that the poor woman had drowned.
But in Victorian Dublin, rumours spread quickly, and it was discovered William Burke Kirwan was living a double life – one that provided a motive for murder.
