Any other closet readers?

I have a number of Victoria Holt novels but don't enjoy reading them because, to me, they are not Gothics, but historical novels with a bit of suspense.

You might try Bride of Pendorric, which I think would qualify as a bona fide Gothic. Although the first few chapters are set on the isle of Capri in the Bay of Naples, the story soon moves to an old castle on the coast of Cornwall, and from that point the tone becomes very "Gothic" indeed.
