The author, checking through the paper entrails from his own declared stand-point (The People's Padre and Crime and Immorality in the Catholic Church) presents his thesis ""that the Roman Catholic Church was deliberately and culpably involved in the assassination of President Lincoln"". The author interrupts himself frequently to hymn the Freemasonry he has embraced and to condemn Vatican methods in the past, present-- and future. (Strange but true-- a certain type of Roman Catholic will go to extremes in proving that all the world's villainies can be traced to Freemasonry-- one coin, two sides.) McLoughlin surveys the religious affiliation of the known Booth conspirators (60% Roman Catholic); proposes the Vatican enmity with Lincoln as based on lawyer Lincoln's successful defense of an Illinois ex-priest; and declares conspirator Surrat's escape, position in the Pope's Zouave Army and the sympathetic protection of priests as the best evidence of Vatican involvement. The trappings of scholarship are here-- footnotes, bibliography and index. Also present is the heat (rather than persuasion) of an articulate ex-priest. The publishers announce an advance printing of 20,000 copies. Never underestimate the size of this market- but don't overestimate the value of this book.
