Mary Kills People

T03:C06 - S03:E06 - A Goddamned Saint

Following a murder at the hospice, Mary and Ben have 24 hours before police have the autopsy results and an iron-clad case to put Mary behind bars for good. Mary thinks Francess father might have the information they need to turn the investigation onto Frances, and uses him to their advantage. But things are complicated when Mary learns Naomi wants to take her own life, and together with Jess they have to convince her that life is worth fighting for. With Mary sidelined, an emotional Des makes a rash play to bring Frances to justice on his own. Mary, however, comes to realize that turning herself in may be the only way to truly bring Frances down consequences be damned.
