The Jeweler's Polish is a Catholic historical fiction novel set primarily in the small Mediterranean island of Malta at the time of the Knights Hospitaller of Saint John. Containing a near-gothic narrative that includes knightly orders, Masons, Illuminati, conspiracies, curses, mysterious jewels, apparitions of spirits, poisoners, gender dysphoria, the evil eye, and incest, The Jeweler's Polish presents to readers the 21st century young Englishwoman, Emerald Rohan Grady, and her ancestral namesake, the Lady Emerald Esther Maria de Rohan, niece of the kindly but corrupt Grandmaster Emmanuel de Rohan-Polduc of the Order of Saint John. But who, in reality, was Lady Emerald? Who was Lucas de Pinto? What made Captain Azzopardi meet his men in secret, at nighttime, in the historical city of Valletta? Who betrayed the kingdom of God and worked for the kingdom of Man? Why did Lady Emerald have to meet Pope Pius VI in Rome? How were the Jesuits and the Masons involved? Above all, who was the Repentant?
