Scullery Maid
They always forget about the scullery maid, these professional types.
Oh sure, they remember us if there’s a locket missing, or a brooch, or a bit of cash. But they usually head for the housemaids and lady’s attendants first: they even check with the butlers and valets before us. We’re a sort of last resort. It’s the same story when a young gentleman goes missing, his bed unslept in: even if we’re pretty, they still talk to chambermaids first. The same goes for serious crime. Nobody ever seriously talks to the scullery maids or truly suspects them of having the brains to pull off a haul. They think there's no way they could gain access to a firearm: a knowledge of poison is laughably beyond a mere servant girl's comprehension.
It makes my life easier in more ways than one. Too bad police are so thick skulled: it'd be good cover to have one for a partner.
