Beatrice Gribble is a Westminster Templar hunt against a would-be lady-in-waiting who, after repeated rejections, has told the Templars she plans to kill the Queen's consort. Kill her with a voltaic bomb for full sync.
Gribble is beating a woman when you arrive and ranting about the rich ladies chosen over her despite her claimed Spanish royal ancestry. Her grievance is that society never accepted her, and she wants revenge on the women who got the post instead.
Gribble is one of three Templar hunts in Lilla Graves' Westminster with Wallace Bone and Edgar Collicott. The borough's bounties are Harrison Harley, Ivan Bunbury and Wade Lynton, and the Blighters hold Devil's Acre and Blue Anchor Alley.
The voltaic bomb is Alexander Graham Bell's electric grenade. It is meant to stun, but its charge is strong enough to kill, and that is what the challenge needs here. Gribble is standing over the woman she is beating, so she makes an easy target for a thrown bomb from a rooftop or corner. Make sure the electrical blast is what kills her, not a follow-up blade.

Wallace Bone
