If anything (e.g. Devin Chaloux - he should be back here under this name, not "radioplug" - said in one of his last posts having the intention to write a fugue) I would recommend Bach's Sonata for Violin Solo nr. 3, 2nd mvt.; it says "Fuga".
I listened to it for the first time, i.e it caught me, mygod, what a piece, what a fugue!

Devin, listen to it, try to catch it and study the score.

 

Never heard a fugue like this one! - on a single violin!!
