Mildred Graves is a Lambeth bounty: the indebted sister of Westminster gang leader Lilla Graves, who works at a Lambeth cemetery and has been burying Lilla's victims without death certificates. Kidnap her and bring her to Abberline alive.
Mildred squandered an inheritance and took the cemetery job to cover her debts. She resents doing Lilla's dirty work, since it risks her job, but is too afraid of her sister to refuse.
She begs you to arrest the Blighters instead and warns that taking her in will not slow Lilla down. Abberline agrees, remarking that the sister is the real menace.
Lilla Graves, Mildred's sister, is the Blighter leader of Westminster and a former heavyweight champion. Lilla's own page notes that the two kept in touch after Mildred moved to Lambeth, and that Lilla used the link to get rid of bodies in the Lambeth cemetery. Capturing Mildred cuts that arrangement, though Mildred insists it will not stop Lilla.
Cletus Strain runs Lambeth for the Templars. Besides its bounties the borough has Templar hunts on Martin Church, the Lambeth Bullies and the Fletchers, and Blighter strongholds at Battersea Bellows and Echostreet Alley.
A Blighter crew is with her at the graveside and mentions the police are close behind, so the area is busy. Take her quietly while she argues with them. When she escapes she calls for help and promises to talk to her sister, which can draw the Blighters back in. Deliver her to Abberline alive to fully sync.
