Can’t find name of pre-19th century novel described as the ‘greatest tragedy in literature. Please help.

Hi! I was watching the series The Count of Monte Cristo (2024), starring Sam Claflin. In one episode, Edmund talks with Father Faria about a book, but they never mention the title—only this exchange:

Faria: “At the sight of him, the soldiers started shooting. That’s how one of the greatest tragedies in the history of literature ends.”
Edmund: “Probably the best I’ve ever known.”

I know that Edmund and Father Faria met in 1818, so this novel would have to exist before that year. I’m not sure whether this book is real or was made up for the show.

I’d really like to find it because if it does exist, I want to read it.
Does anyone recognize this book or have any idea where this quote might come from? Thanks in advance for help.
