oooh thank you! lots of food for thought there!
I was going for an engineer because of the genuine case of Margaret Anne Bulkley aka Dr James Barrie as a doctor....

As to Jane and Caleb, well that's the work in progress, in which I am weaving 3 different mysteries together after the fashion of a Chinese detective novel [I am a devotee of Robert Van Gulik's Judge Dee stories] and it's tough, but fun. Jane has received a royal command to turn up for the season and show off that demi-parure, Caleb is showing a lot of interest in owning a Draisine aka Pedestrian Curricle aka hobby-horse, Simmy has an old friend whom Jane runs into, and meanwhile there is a lady whose accent occasionally shows hints of the Parish of Bow, an an unwholesomely high number of people inheriting from suddenly dead relatives.
I was thinking of doing Simmy at University as a sort of Georgian Sherlock Holmes when I ran out of Jane and Caleb ideas
Meantime I've been writing some humourous noir cyberpunk short stories to amuse myself but I haven't posted any because I'm not too sure if they'd be suitable here.
