Your ANFRACTUOSITY is confusing me!

What's the word I'm thinking of? Today, it's....

ANFRACTUOSITY (noun)

The quality of having many many twists and turns

"There are chance anfractuosities of ruin in the upper portions of the Coliseum which offer a very fair imitation of the rugged face of an Alpine cliff."
--Henry James, Italian Hours (1909)

Speaking of Henry James, he's a pretty anfractuous writer, in my reading experience. Even the title of perhaps his most famous work, The Turn of the Screw, is twisty. And here's a typically anfractuous Jamesian sentence: "He fairly caught himself shooting rueful glances, shy looks of pursuit, toward the embodied influence, the definite adversary, who had, by a stroke of her own, failed him, and on a fond theory of whose palpable presence he had, under Mrs. Newsome's inspiration, altogether proceeded." If you can parse that, you’re a better ex-English major than I am. (TWITO, page 14)
