Looking for a book title, old style historical romance

My mom is in her 70s and she was given a two-volume set of books by her mom. She’s trying to figure out what the books were.

What she knows:

“Do you remember a small two-volume book set I had that was from my mother? It was printed in the late 1800’s or early 1900’s and had a “dirty” gold hardcover. I remember the title as “Tarquisaris” or something similar. The story line was mystery/romance set in the late 1700"s maybe.”

Ring any bells for anyone?

Try this:

"Aphra Behn’s The Fair Jilt, Or, The Amours of Prince Tarquin and Miranda (1688) is the story of a charming, daring, and determined lady who contemplates even murder to attain her love. It is all in vain, however, and her love transforms later into aggressive hatred. "

There’s a few pages of the book online here :

see if that rings a bell

Sorry for the delay, but no. That doesn’t seem to be it.

Bump for anyone who might not have seen this.

HOw about this? Don Tarquinio. Written around the right time. No description given of the story line.

That looked like a great guess, but before she had a chance to figure out if that was it, she found out that it was Taquisara, by F. Marion Crawford.

Thanks to you both for your very good tries!
