These were the closest I could come up with at the moment:

The Long Road has angst and some darkness, but a happy ending.

Another Time, Another World is short and *beautiful* and angsty in the best possible way.

And if I'm permitted to shill my own fic, Jeeves and the Principle of Cause and Effect has serious consequences to their getting caught, although the serious consequences are treated in a not-too serious way. (The premise was basically, "I'm going to make medical institutional torture funny!")

And like others I'd *love* more period music!
