Begone Satan!, is a soul-stirring account of diabolical possession in Earling, Iowa in 1928, in which a woman cursed by her own father was possessed from her 14th year until her 40th year, the year of the exorcism.

Mary Crushes the Serpent, is the author's account of his 30 years' experience as an exorcist. He writes: "I will first state what the demons said about the present state of the Church, and then I will relate the diabolical plans which they, according to their own admission, are keeping under cover... The object of this document is to show the maternal solicitude of the Blessed Virgin for the Church of her Divine Son, as also to publish the plan Mary seems to have adopted to come to the aid of the Church in her present plight."
