What has the author Helm Bruce written?

It seems like you're asking about an author named Helm Bruce, but there doesn't appear to be an author by that name with any published works readily found online.

It's possible that:

* The name is misspelled: Could you double-check the name?

* The author is relatively unknown: Perhaps they have only published in niche genres or haven't gained widespread recognition yet.

* They write under a different name: Some authors use pen names, so it's possible this author goes by a different name when publishing.

To help me find the author, could you provide any additional information you have, such as:

* Genres they write in: (e.g., fantasy, romance, mystery)

* Specific titles or books they've written: (even if you only remember part of the title)

* Any other details about them: (e.g., nationality, time period they wrote in)
