Mary Jeffries — London Housekeeper and Fixer

Mary Jeffries knows what happens when wealthy clients think a closed door makes a private act disappear from the world.
Mary Jeffries runs a discreet adult entertainment house and private meeting network in London. The campaign keeps all adult material non-explicit and focuses on what makes her useful: controlled access, staff loyalty, private rooms, client secrets and the ability to move a frightened witness without advertising that anyone has moved at all.

Read the Room. Jeffries has advantage on Wisdom (Insight) checks to detect intimidation, pressure or imminent violence in a household.

What Is Mary Jeffries Doing Right Now?
Mary is sheltering a household servant who heard a noble client discuss forged confiscation orders. The witness is more frightened of the noble’s retainers than of official law.
A rival has begun selling rumours that Mary is responsible for the leak, putting workers and clients at risk even though she has not yet told anyone what the witness heard.
Encounters
- A private client confession overlaps the party’s investigation.
- Mary needs outsiders because involving officials would expose the wrong people.
- A safe room has been compromised without the door being forced.
- She refuses to identify a client but gives enough detail for the party to recognise him.
Personality, Appearance and Manner
Practical, discreet and acutely aware of power shifts inside a room. She protects workers because frightened staff are both vulnerable people and dangerous loose ends.
She dresses as a prosperous business owner, keeps keys close and never leaves sensitive records in the room where negotiations occur.
Relationships and Influence
- Workers and doorkeepers: the people she trusts first.
- Theresa Berkley and Damaris Page: peers and competitors in London’s discreet-house economy.
- Mary Frith: useful when an object must move outside respectable channels.
- Affluent clients: sources of information and risk.
Equipment and Possessions
- Keys and coded ledgers
- Private correspondence
- Emergency cash
- Safe-house instructions
- Trusted doorkeepers and messengers
Using This NPC at the Table
Mary should be a social node rather than an exposition machine. Information comes with duties: protect a worker, avoid exposing innocent clients, move a witness or repay a favour.
Adventure Hooks
- The Hidden Witness: one servant knows which noble ordered the forgery.
- The Compromised Room: someone found a safe house without following anyone there.
- The False Rumour: a rival deliberately turns clients against Mary.
- The Sealed Confession: a document is safer unread until the right patron receives it.
- The Three Keepers: Jeffries, Berkley and Page must cooperate against a common threat.

Mythical and Historical Context
Mary Frances Jeffries was a Victorian London businesswoman involved in serious exploitation; her documented prosecution belongs to 1885, not 1454. This is a fictional medieval namesake used to explore the influence and danger of information held by household networks; nothing in this game should excuse the abuses associated with the historical figure. See the Royal Historical Society’s historical account for the real nineteenth-century scandal. The 1454 safe rooms, alliances and encounters are invented and non-explicit.
Sources and Adaptation
Adapted from the historical Mary Jeffries as a fifteenth-century London fixer. Explicit adult content is excluded; the useful campaign core is discretion, workers, clients, safe rooms and information.
