After the death of their beloved dog Whym Chow, Katharine Bradley and Edith Cooper, who write collectively as Michael Field, underwent a radical spiritual and poetic shift by converting to the Roman Catholic Church. Each partner viewed this shift differently. Bradley focused on the ways in which Whym Chow’s death represented a rupture in their domestic Trinity, while Cooper focused on the sacrificial aspects of euthanising the dog as an act of their own will. Converting to the Roman Catholic Church impacted both Bradley and Cooper’s relationship with one another and their poetic creativity and dominated the final years of their shared life.
