In an era of deepening distrust and proliferating conspiracies, A Dangerous Man tells the true story of how conviction can harden into obsession—and push an ordinary life toward the edge.

Set against the monuments and rituals of American authority, A Dangerous Man follows Dr. John David Sabow, a respected neurologist in South Dakota whose life is irrevocably altered after his brother, a decorated Marine colonel, is found dead under circumstances officially ruled a suicide. What begins as grief turns into a decades-long pursuit of truth—one that places David in direct conflict with the military, law enforcement, and the federal government.

As doors close, David’s conviction hardens as his isolation grows and the line between moral certainty and dangerous obsession begins to blur.
