Input needed: Fun things for a courtesan to find out.
That lady who's just got the status to get away with refusing to tell her noble family whose baby bump that is? Everyone thinks it's that notoriously rakish guy she hangs out with, but actually it's someone incredibly important plot/politics wise, to whom said rake owes a favour. Only the lady's maid (courtesan's buddy) knows this.
Courtesan has enough contacts to put together and realise that the up-and-coming young noble from off East who's trying to marry an eligible and wealthy political keystone is, in fact, using loans for credit on other loans and pulling off an elaborate Great Gatsby scam.
That supposed three-way feud among certain feisty younger members of rival houses, which has involved mild injuries, public humiliation, one kidnapping and terrible insults to family and dignity, is not, in fact, something plotters can leverage like they think they can. It's a perfectly consensual kink game carried on under the elders' noses, and all participants are loving it.
The nice little old lady who's a holdover at court from a powerful husband who died a few years back still has a nice stash of poison if you need it, dearie, and can get you some very interesting substances in return for a favour or so.
That couple married for political advantage who live in a villa beside the batchelor pad of two gentlemen reknowned for wealth and taste are both carrying on affairs with said gentlemen, to everyone's satisfaction. This arrangement was founded before the marriage, and there's a secret tunnel under the villa wall that comes out in the orangery/middle of the single guys' dining room under a fancy grille.
Contact #5's horribly inbred pedigree animal is going to have its babies ready for adoption soon - if Courtesan wants one, she can have one. It will be worth a lot to collectors but might also die of genetic defects if not watched like a hawk and pampered like a soufflé.
The relative of someone important has been sneaking out at night to catch and eat various bugs. Whether they're cursed or going senile or insane, the contact is very worried about them, especially with their place in city politics. Aside from the nightly jaunts, the relative seems fine. They get a terrible blank look and immediately forget all mention of the subject if questioned, however.
Rebellious Scion Flirting With Revoloutionary Politics might have actually met someone who knows what they're talking about, though it's not clear whom and they're not telling. The upper-class rebel is too earnest and daft to be a danger to the establishment in themselves, but how long have they been leaking information, and in which direction...?
