What I Mean by a Clean Conspiracy Thriller

By S.F. Baumgartner

I describe Black Gold Secret as a clean action-adventure conspiracy thriller. The word clean tells readers something important about the content, but it does not mean the story is quiet or free of danger.

The thriller stakes remain

The Mercer brothers face physical danger, powerful opponents, and a conspiracy that crosses borders. Investigations lead into damaged structures, isolated locations, and evidence someone has worked hard to erase. Characters make decisions under pressure, and those decisions have consequences.

I don’t remove danger from the story. I choose where the narration places its attention.

Violence is written for tension and consequence rather than graphic spectacle. The books contain no profanity or substitute profanity and no explicit sexual content. Romance remains a restrained undercurrent, expressed through trust, loyalty, and choices made when the characters are under pressure.

Faith is part of the moral landscape

Faith may appear through prayer, private grounding, or the way a character understands responsibility. It is part of the characters’ lives without stopping the investigation for a sermon.

That balance matters to me. Readers can enter a dangerous conspiracy, follow the evidence, and experience the suspense without being surprised by explicit material.

Where Black Gold Secret begins

Black Gold Secret begins when investigative reporter Gemma Klein receives an anonymous package connected to Blackwater Rig Three. The offshore disaster was ruled an accident more than twenty-five years ago. Luke Mercer has personal reasons to distrust that conclusion and equally strong reasons to distrust the reporter asking about his father.

The novel delivers a complete central investigation while opening the larger Mercer Files conspiracy. It releases September 8 and is available for preorder on Amazon.
