The Adventures and Experience of Joseph H Jackson is a gripping narrative that sheds light on the author's firsthand encounters in the city of Nauvoo. With a goal to expose the dark underbelly of religious deceit, Jackson recounts his efforts to gain the trust of the enigmatic figure known as the Prophet. Employing deceptive tactics and practicing dissimulation, he uncovers the true intentions and operations of the Prophet, which he believes are fraught with iniquity.

Jackson acknowledges the incredulity that may arise from his revelations, recognizing the difficulty in convincing others of the depravity that permeates Nauvoo. Nevertheless, he justifies his own actions, emphasizing that the end justifies the means. Drawing parallels to instances of organized crime or counterfeiting, he argues that sometimes one must become an apparent accomplice to expose the secret machinations of those in power.

Throughout the book, Jackson assures listeners that he presents only what he personally witnessed and heard in Nauvoo, refraining from embellishment or malice. He asserts that many of his claims can be corroborated by substantial evidence and is prepared to provide such proof if challenged.

The author contemplates the puzzling question of how a morally corrupt individual like Joe Smith could wield such absolute control over the minds of his devout followers. He highlights the overpowering influence of blind fanaticism, describing how it engenders unwavering loyalty to the point where followers would readily commit acts of violence, believing them to be divinely sanctioned.

One notable aspect that permeates Smith's commands, whether delivered in public or private, is their invocation "in the name of the Lord." Publicly, Smith speaks as the mouthpiece of the divine, while privately, he uses the Lord's name to orchestrate the vilest of plans, including assassination, robbery, and seduction. The book portrays Smith as a blasphemous figure who exploits his followers' faith for his own nefarious ends.

It is important to note that the writing of this narrative predates the recent disturbances in Hancock County that led to the deaths of Joe Smith and his brother. The author expresses regret that the publication did not occur while they were alive, but nevertheless hopes that his account will convince the world of their deserved fate. Despite his relatively brief encounter with the Mormons, Jackson's experiences expose a level of corruption and depravity that he previously believed unimaginable.
