Dodo Collections brings you another classic from Max Brand, ‘The Untamed.’ The mysterious Whistlin' Dan Barry rides a black stallion named Satan, followed by a wolf dog named Black Bart. Dan has his own problems, but they multiply when he encounters Jim Silent and his outlaw gang. Frederick Schiller Faust (1892-1944) was an American fiction author known primarily for his thoughtful and literary Westerns. Faust wrote mostly under pen names, and today he is primarily known by one, Max Brand. Others include George Owen Baxter, Martin Dexter, Evin Evans, David Manning, Peter Dawson, John Frederick, and Pete Morland. Faust was born in Seattle. He grew up in central California and later worked as a cowhand on one of the many ranches of the San Joaquin Valley. Faust attended the University of California, Berkeley, where he began to write frequently. During the 1910s, Faust started to sell stories to the many emerging pulp magazines of the era. In the 1920s, Faust wrote furiously in many genres, achieving success and fame, first in the pulps and later in the upscale "slick" magazines. His love for mythology was, however, a constant source of inspiration for his fiction and his classical and literary inclinations. The classical influences are particularly noticeable in his first novel The Untamed (1919), which was also made into a motion picture starring Tom Mix in 1920.

Western novel, first published in 1902. According to Wikipedia: "Mary Hallock was born November 9, 1847, in Milton, New York, of English Quaker ancestry. A singular girl and youth, she attended the Female Collegiate Seminary in Poughkeepsie, New York, then studied art in New York City at the new Cooper Institute School of Design for Women. By her early twenties she had become established in New York City as an accomplished artist-illustrator for notable publishers there. In 1876 Hallock married a young mining engineer, Arthur De Wint Foote, then moved cross-continent to live with him at the New Almaden mine near San Jose, California. Subsequently, as Arthur pursued his engineering career, she followed him throughout the West; to Leadville, Colorado, to Deadwood, South Dakota, then to Boise, Idaho, where Arthur originated a major irrigation project on the Boise River; then to Morelia, Michoacán, Mexico, and finally to Grass Valley, California, where Arthur advanced to managing the North Star mine, and retired there...Wallace Stegner's novel Angle of Repose (Pulitzer Prize, 1971) is based directly upon Mary Hallock Foote's extensive personal correspondence.'

He wrote thirteen novel sequels, nine other fantasy novels, and a host of other works (55 novels in total, plus four "lost" novels, 83 short stories, over 200 poems, an unknown number of scripts, and many miscellaneous writings), and made numerous attempts to bring his works to the stage and screen. His works anticipated such century-later commonplaces as television, augmented reality, laptop computers (The Master Key), wireless telephones (Tik-Tok of Oz), women in high risk, action-heavy occupations (Mary Louise in the Country), and the ubiquity of advertising on clothing (Aunt Jane's Nieces at Work)."

Dodo Collections brings you another classic from Max Brand, ‘Black Jack’. ? “The moment he rose out of the chair and faced them, Gainor had stopped short. He was quite capable of fast thinking, and now his glance flickered from Terry to the sheriff and back again. It was plain that he had shrewd suspicions as to the purpose behind that call. The sheriff was merely confused. He flushed as much as his tanned-leather skin permitted. As for Terry, the moment his glance fell on the sheriff he felt his muscles jump into hard ridges, and an almost uncontrollable desire to go at the throat of the other seized him. He quelled that desire and fought it back with a chill of fear.” ? Frederick Schiller Faust (1892-1944) was an American fiction author known primarily for his thoughtful and literary Westerns.

According to Wikipedia: "Chrétien de Troyes (Old French Christian) was a French poet and trouvère who flourished in the late 12th century. Perhaps he named himself Christian of Troyes in contrast to the illustrious Rashi, also of Troyes. Little is known of his life, but he seems to have been from Troyes, or at least intimately connected with it, and between 1160 and 1172 he served at the court of his patroness Marie of France, Countess of Champagne, daughter of Eleanor of Aquitaine, perhaps as herald-at-arms (as Gaston Paris speculated). His work on Arthurian subjects represents some of the best regarded of medieval literature. His use of structure, particular in Yvain, the Knight of the Lion, has been seen as a step towards the modern novel."

Dodo Collections brings you another classic from H. Rider Haggard, ‘Colonel Quaritch, V.C.’ ? This is not a typical adventure book yet it is full of mystery and intrigue including a coerced marriage, bigotry, adultery, murder and a buried treasure! ?

Listen as the tale unfolds and guess where the treasure is hidden that can save them all!? ? Sir Henry Rider Haggard was an English writer of adventure novels set in exotic locations, predominantly Africa, and the creator of the Lost World literary genre. His stories, situated at the lighter end of the scale of Victorian literature, continue to be popular and influential. He was also involved in agricultural reform and improvement in the British Empire. ?

Dodo Classics brings you another classic from Henry James, ‘The Sacred Fount.’ ? The narrator speculates upon the relationships between house guests at a weekend party. The Sacred Fount is a curiously intimate revelation of Henry James’ interests and methods. Henry James, OM, son of theologian Henry James Sr., brother of the philosopher and psychologist William James and diarist Alice James, was an American-born author, one of the founders and leaders of a school of realism in fiction. He spent much of his life in England and became a British subject shortly before his death. He is primarily known for a series of major novels in which he portrayed the encounter of America with Europe. His plots centered on personal relationships, the proper exercise of power in such relationships, and other moral questions. His method of writing from the point of view of a character within a tale allowed him to explore the phenomena of consciousness and perception, and his style in later works has been compared to impressionist painting. ? James insisted that writers in Great Britain and America should be allowed the greatest freedom possible in presenting their view of the world, as French authors were. His imaginative use of point of view, interior monologue and unreliable narrators in his own novels and tales brought a new depth and interest to realistic fiction, and foreshadowed the modernist work of the twentieth century. An extraordinarily productive writer, in addition to his voluminous works of fiction he published articles and books of travel writing, biography, autobiography, and criticism,and wrote plays, some of which were performed during his lifetime with moderate success. His theatrical work is thought to have profoundly influenced his later novels and tales.

First published during World War I. The book begins: "It is a curious circumstance that an invention, which is hailed as being one of the greatest achievements ever recorded in the march of civilisation, should be devoted essentially to the maiming of humanity and the destruction of property. In no other trend of human endeavour is this factor so potently demonstrated as in connection with Man's Conquest of the Air."

First published in 1915, from Every Boy's Mechanical Library. "This work is not intended to set forth the exploits of aviators nor to give a history of the Art. It is a book of instructions intended to point out the theories of flying, as given by the pioneers, the practical application of power to the various flying structures; how they are built, the different methods of controlling them; the advantages and disadvantages of the types now in use; and suggestions as to the directions in which improvements are required."

The Fu Manchu stories, together with his more conventional detective series characters: Paul Harley, Gaston Max, Red Kerry, Morris Klaw, and The Crime Magnet made Rohmer one of the most successful and well-paid authors of the 1920s and 1930s.Rohmer also wrote several novels of supernatural horror, including Brood of the Witch-Queen. Sadly, Rohmer was very poor at managing his wealth and made several disastrous business decisions that hampered him througout his career. His final success came with a series of novels featuring a female variation on Fu Manchu, Sumuru."

Dodo Collections brings you another classic from Sherwood Anderson, ‘"Triumph of the Egg and Other Stories".’ ? This collection of short stories solidified the author's reputation as a major American writer. Despite their narrative simplicity (similar in style to the work of Hemingway, who was highly influenced by Anderson's technique), these stories explore intriguing psychological depths, redolent with personal epiphanies, erotic undercurrents, and sudden eruptions of passion among seemingly repressed, inarticulate Midwesterners. ? Anderson was born on Sept. 13, 1876, in Camden, Ohio. He never finished high school because he had to work to support his family. By 1912, he was the successful manager of a paint factory in Elyria, Ohio, and the father of three children by the first of his four wives. In 1912, Anderson deserted his family and job. In early 1913, he moved to Chicago, where he devoted more time to his imaginative writing. He became a heroic model for younger writers because he broke with what they considered to be American materialism and convention to commit himself to art.

Sequel to the well-known classic. The story begins: "THAT homely proverb, used on so many occasions in England, viz. "That what is bred in the bone will not go out of the flesh," was never more verified than in the story of my Life. Any one would think that after thirty-five years' affliction, and a variety of unhappy circumstances, which few men, if any, ever went through before, and after near seven years of peace and enjoyment in the fulness of all things; grown old, and when, if ever, it might be allowed me to have had experience of every state of middle life, and to know which was most adapted to make a man completely happy; I say, after all this, any one would have thought that the native propensity to rambling which I gave an account of in my first setting out in the world to have been so predominant in my thoughts, should be worn out, and I might, at sixty one years of age, have been a little inclined to stay at home, and have done venturing life and fortune any more." According to Wikipedia: Daniel Defoe (1659/1661 [?] — 1731), born Daniel Foe, was an English writer, journalist, and pamphleteer, who gained enduring fame for his novel Robinson Crusoe. Defoe is notable for being one of the earliest practitioners of the novel, as he helped to popularise the form in Britain, and is even referred to by some as one of the founders of the English novel. A prolific and versatile writer, he wrote more than five hundred books, pamphlets, and journals on various topics (including politics, crime, religion, marriage, psychology and the supernatural). He was also a pioneer of economic journalism."
