The Admirable Secret of the Rosary is a book about the Holy Rosary written by Saint Louis de Montfort a French priest and Catholic saint who died in 1716. The English translation of the book bears the Imprimatur of Archbishop Thomas E. Molloy of the Roman Catholic Diocese of Brooklyn. The book revolves around the views of the rosary and the power of the rosary and consists of a number of short sections called Roses each being about one or two pages long. Each Rose discusses a separate viewpoint about the Rosary and may be addressed to a different cross section of the audience, e.g. priests versus lay people.
