The Aristocrat Is Always Right: Superb.
Judith has perfected the manner of a patriarchal pillar of the British aristocracy, and employs it to full advantage. This enables her to commit social outrages such as atheism, shagging anything with a pulse and even pacifism, without incurring the wrath of polite society. If caught by constables in the act of stabbing the Crown Jewels, she could not only avoid arrest, but leave them feeling as if they had committed a terrible faux pas. Fencer: Good.
Judith used to fence a bit at her old school and as an undergraduate; she still occasionally keeps her hand in, if only to maintain a reputation for eccentricity (although she's not as quick as she was). She's not given to actually carrying a sabre around, but can fence single-stick if necessary; predictably, she's a rather better judge of other fencers than she is a fencer herself.

Textual Analysis: Superb.
Judith's academic career has largely been based on working out the *motives* behind arguments and using that to identify their flaws - although naturally she would never be so crass as to resort to ad hominem attacks. This skill can be generally applied to any writing.

Ancient Languages: Superb.
Fluent in Latin and Greek, and can read Hebrew, Aramaic, Coptic, and Sanskrit without much trouble; can struggle through a half-dozen other languages, with the help of a decent library.

Seduction: Great.
Well, one has to enliven dinner-parties somehow.

Raconteur: Great.
Or this way. One doesn't last long in the collegiate system without developing a knack for making gossip more juicy, or deflecting a well-placed barb.

Machines and Suchlike Monstrosities: Terrible.
Much as X would like to shrug off her constricting feminine sensibilities, there's a limit to how many barriers one can stomp over in one lifetime. She's not only incapable of dealing with anything more complex than an eggbeater, she gets incredibly frustrated and cross (at herself and the world in general) when attempting to do so.

Posh Sports: Fair.
Y'know, all the stuff that one has to do if spending the week at a friend's estate. Horse-riding, gamebird shooting, tennis, parlour games. Lack of interest has prevented the development of anything more than basic competence.

Influential Connections: Great.
Judith has known (in various senses) any number of lords, judges, bishops and cabinet ministers, and has danced around the edges of the Bloomsbury set; nor is she scrupulous about calling in favours, if the situation demands.

Suffering Fools: Terrible.
No matter how vital it is to stay on the right side of an idiot, she just can't help herself. At best she can couch her mockery in terms too subtle for the victim to notice; at worst she unleashes blistering disdain.

Respiratory Health: Poor.
Judith smokes a great many cigarillos, and is well on the road to lung cancer. She's good at concealing the effects when around people, but too much strenuous effort just isn't feasible.

During the Great War, remained in Cambridge and loudly decried the War, the Government and all of Society, getting a dig in at the Church and the Press whenever she had any spare vitriol. (She also took copious advantage of the absence of most of the staff to advance her career). Her (first) husband, Major William Hertford, dutifully marched off to be killed in action at Ypres.
