William Walker Atkinson, Magus Incognito: The Secret Doctrine of the Rosicrucians
The student of the history of occultism and the esoteric teachings, and even the average reader of current books and magazines, finds many references to "The Rosicrucians," a supposed ancient secret society devoted to the study of occult doctrines and the manifestation of occult powers. But when such person seeks to obtain detailed information concerning this supposed ancient "order" he finds himself baffled and defeated. Before acknowledging the futility of the quest, however, he usually investigates one or more so-called "orders" having as a part of their title the word "Rosicrucian," only to find himself invited to join such "order" upon the payment of a fee or fees ranging from a small amount in some cases to quite large amounts in others, each "order" claiming to be the "only original order," and asserting that all the others are base imitators. This book will give you all the insights on this secret order.
