Lolita

Twas a brillig begin with the slithy tothes but alas!, lost me halfway, at the boarding school...

I picked up bits and pieces from a plethora of aristocratic French & black humor:
Little Lo is languished, limp with sickness.
Old Man Haze leaves for a little,
finds her pregnant,
murders her molester.

Correct?, sed
Quis "Gaston" est?
