Carthage Conspiracy deals with the general problem of Mormon/non-Mormon conflict, as well as with the dramatic story of Mormon prophet Joseph Smith, his brother Hyrum, and their alleged assassins. It places the infamous event at the Carthage jail (1846) and the subsequent murder-conspiracy trial in the context of Mormon and American legal history, and deals with the question of achieving justice when crimes are politically motivated and popularly supported.

Joseph Smith's father, Joseph Smith Sr., first occupied the hereditary office of Presiding Patriarch of the Church of Jesus Christ of Latter-day Saints. Thereafter, it became a focal point for struggle between those appointed and those born to leadership positions. This new edition of Lost Legacy updates the award-winning history of the office. Irene M. Bates and E. Gary Smith chronicle the ongoing tensions around the existence of a Presiding Patriarch as a source of conflict between the Smith family and the rest of the leadership. Their narrative continues through the dawning realization that familial authority was incompatible with the LDS's structured leadership and the decision to abolish the office of Patriarch in 1979. This second edition, revised and supplemented by author E. Gary Smith, includes a new chapter on Eldred G. Smith, the General Authority Emeritus who was the final Presiding Patriarch. It also corrects the text and provides a new preface by E. Gary Smith.
