This work, first published around 1680, resembles the work of Malthus on the implications of population growth, which was written more than a hundred years later. According to Wikipedia: "Sir William Petty (26 May 1623 – 16 December 1687) was an English economist, scientist and philosopher. He first became prominent serving Oliver Cromwell and Commonwealth in Ireland. He developed efficient methods to survey the land that was to be confiscated and given to Cromwell's soldiers. He also managed to remain prominent under King Charles II and King James II, as did many others who had served Cromwell. He was Member of the Parliament of England briefly and was also a scientist, inventor, and entrepreneur, and was a charter member of the Royal Society. It is for his theories on economics and his methods of political arithmetic that he is best remembered, however, and to him is attributed the philosophy of 'laissez-faire' in relation to government activity. He was knighted in 1661."

First published in 1916. According to the Preface: " Having been connected for many years with two of the largest and most successful private detective agencies in this country, both as an operator and as an official, and having been requested to outline briefly and concisely the most modern and up-to-date methods employed by leading detectives and private detective agencies of today, I shall confine myself in these pages to facts and a few personal experiences. I will endeavor to show that any person possessed of average intelligence, and who will use good common sense, can become a successful detective, regardless of his present or previous occupation."

Sequel to Caught in the Net. According to Wikipedia: "?mile Gaboriau (November 9, 1832 – September 28, 1873) was a French writer, novelist, journalist, and a pioneer of detective fiction... after publishing some novels and miscellaneous writings, found his real gift in L'Affaire Lerouge (1866). The book, which was Gaboriau's first detective novel, introduced an amateur detective. It also introduced a young police officer named Monsieur Lecoq, who was the hero in three of Gaboriau's later detective novels. The character of Lecoq was based on a real-life thief turned police officer, Eugène Fran?ois Vidocq (1775–1857)."

According to Wikipedia: "Mary Roberts Rinehart (August 12, 1876-September 22, 1958) was a prolific author often called the American Agatha Christie.[1] She is considered the source of the phrase "The butler did it", although she did not actually use the phrase herself, and also considered to have invented the "Had-I-But-Known" school of mystery writing.... Rinehart wrote hundreds of short stories, poems, travelogues and special articles. Many of her books and plays, such as The Bat (1920) were adapted for movies, such as The Bat (1926), The Bat Whispers (1930), and The Bat (1959). While many of her books were best-sellers, critics were most appreciative of her murder mysteries. Rinehart, in The Circular Staircase (1908), is credited with inventing the "Had-I-But-Known" school of mystery writing. The Circular Staircase is a novel in which "a middle-aged spinster is persuaded by her niece and nephew to rent a country house for the summer. The house they choose belonged to a bank defaulter who had hidden stolen securities in the walls. The gentle, peace-loving trio is plunged into a series of crimes solved with the help of the aunt. This novel is credited with being the first in the "Had-I-But-Known" school."[3] The Had-I-But-Known mystery novel is one where the principal character (frequently female) does less than sensible things in connection with a crime which have the effect of prolonging the action of the novel. Ogden Nash parodied the school in his poem Don't Guess Let Me Tell You: "Sometimes the Had I But Known then what I know now I could have saved at least three lives by revealing to the Inspector the conversation I heard through that fortuitous hole in the floor." The phrase "The butler did it", which has become a cliché, came from Rinehart's novel The Door, in which the butler actually did do it, although that exact phrase does not actually appear in the work."

Elizabeth von Arnim's novel tells the story of four dissimilar women in 1920s England who leave their damp and rainy environments to go on a holiday to a secluded coastal castle in Italy. Mrs Arbuthnot and Mrs Wilkins, who belong to the same ladies' club, but have never spoken, become acquainted after reading a newspaper advertisement for a small medieval Italian castle on the shores of the Mediterranean to be let furnished for the month of April. They find some common ground in that both are struggling to make the best of unhappy marriages. Having decided to seek other ladies to help share expenses, they reluctantly take on the waspish, elderly Mrs Fisher and the stunning, but aloof, Lady Caroline Dester. The four women come together at the castle and find rejuvenation in the tranquil beauty of their surroundings, rediscovering hope and love.

Mansfield's Bliss, and Other Stories, published in 1920, secured the author's literary reputation. While readers and critics at the time generally lauded the short fiction collection, a few reviewers objected to its controversial subject matter - infidelities, discussions of sexuality, cruel and superficial characters. Today "Bliss" is one of Mansfield's most frequently anthologized stories and still resonates with modern readers.

In "Marriage as a Trade" Hamilton asserts that "woman, as we know her to-day, is largely a manufactured product; that the particular qualities which are supposed to be inherent in her and characteristic of her sex are often enough nothing more than the characteristics of a repressed class and the entirely artificial result of her surroundings and training."

This tale of scientific rejuvenation was the number one best seller of 1923. The story centers on the relationship between thirty-four year old columnist Lee Clavering, and Mary Zattiany, a 58 year old woman who, through modern science, has regained her youth. The story takes place within New York’s high society and there is much criticism of both the older and younger generations in the 1920s. The older generation is argued to be unreasonably caught up in convention while the younger generation is shown as being too eager to flout their straying from those same conventions.

In the vaulted Gothic towers of Notre-Dame lives Quasimodo, the hunchbacked bellringer. Mocked and shunned for his appearance, he is pitied only by Esmerelda, a beautiful gypsy dancer to whom he becomes completely devoted. Esmerelda, however, has also attracted the attention of the sinister archdeacon Claude Frollo, and when she rejects his lecherous approaches, Frollo hatches a plot to destroy her that only Quasimodo can prevent. Victor Hugo's sensational, evocative novel brings life to the medieval Paris he loved, and mourns its passing in one of the greatest historical romances of the nineteenth century.

Dodo Collections brings you another classic from Max Brand, ‘Bull Hunter.’ Hunter was a man who could rip a tree trunk from the ground with his bare hands or tame the wildest stallion with his kind manner. Nobody west of the Pecos would have dared run afoul of the mighty frontiersman. But Pete Reeve didn't have the reputation of a dead shot because he relied on his common sense. Then Bull and Pete crossed paths, and townsfolk from Cheyenne to San Antonio braced for the battle. 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.

Dodo Collections brings you another classic from H. Rider Haggard, ‘The Ghost Kings.’ "The Zulus have a strange story of a white girl who in Dingaan's day was supposed to 'hold the spirit' of some legendary goddess of theirs who is also white. This girl, they say, was very beautiful and brave, and had great power in the land before the battle of the Blood River, which they fought with the emigrant Boers. Her title was Lady of the Zulus, or more shortly, Zoola, which means Heaven." This is her story. 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. His breakout novel was King Solomon's Mines (1885), which was to be the first in a series telling of the multitudinous adventures of its protagonist, Allan Quatermain. Haggard was made a Knight Bachelor in 1912 and a Knight Commander of the Order of the British Empire in 1919. He stood unsuccessfully for Parliament as a Conservative candidate for the Eastern division of Norfolk in 1895. The locality of Rider, British Columbia, was named in his memory.

Classic Western. According to Wikipedia: "Zane Grey (1872 – 1939) was an American author best known for his popular adventure novels and stories that presented an idealized image of the rugged Old West. As of June 2007, the Internet Movie Database credits Grey with 110 films, one TV episode, and a series, Dick Powell's Zane Grey Theater based loosely on his novels and short stories."

Short story. According to Wikipedia: "Harriet Elisabeth Beecher Stowe (June 14, 1811 – July 1, 1896) was an American abolitionist and author. She came from a famous religious family and is best known for her novel Uncle Tom's Cabin (1852). It depicts the harsh life for African Americans under slavery. It reached millions as a novel and play, and became influential in the United States and Great Britain. It energized anti-slavery forces in the American North, while provoking widespread anger in the South. She wrote 30 books, including novels, three travel memoirs, and collections of articles and letters. She was influential for both her writings and her public stands on social issues of the day."

Three classic Christas stories: The Birds' Christmas Carol, The Romance of a Christmas Card, and The Old Peabody Pew. According to Wikiipedia: "Kate Douglas Wiggin (September 28, 1856–August 24, 1923) was an American children's author and educator. Kate Douglas Smith Wiggin was born in Philadelphia, and was of Welsh descent. A graduate of Abbot Academy, Class of 1873, she started the first free kindergarten in San Francisco in 1878 (the Silver Street Free Kindergarten). With her sister in the 1880s she also established a training school for kindergarten teachers... Still devoted to her school, she began to raise money for it through writing, first The Story of Patsy (1883), then The Birds' Christmas Carol (1887). Both privately printed books were issued commercially by Houghton Mifflin in 1889, with enormous success. Ironically, considering her intense love of children, Kate Wiggin had none. Her husband died suddenly in 1889, and Kate took her grief home to Maine. For the rest of her life she struggled with depression, and in order to combat it she traveled as frequently as she could, dividing her time between writing, trips to Europe, and giving public reading for the benefit of various children's charities. Her literary output included popular books for adults, scholarly work on the educational principles of Friedrich Froebel, and of course the classic children's novel Rebecca of Sunnybrook Farm (1903) Wiggin's home in the Salmon Falls section of Hollis, Maine."

John Buchan (1875-1940) was a Scottish novelist, historian, and politician, who served as governor general of Canada. His best-known fiction is The Thirty-Nine Steps, featuring the action hero Richard Hannay.
