Who wrote the play black hearted villain?

There doesn't seem to be a play called "Black Hearted Villain". It's possible that:

* The title is slightly wrong: Perhaps there's a similar title, like "The Black-Hearted Villain", or a play with a similar theme.

* It's a lesser-known play: It might be a local or amateur production with limited online presence.

Could you provide more context, like:

* Where did you hear about this play?

* What is the play about?

* Do you know the year it was written or performed?

With more information, I might be able to help you find the playwright.
