Mr. Hungerton, her father, really was the most tactless person upon earth,—a fluffy, feathery, untidy cockatoo of a man, perfectly good-natured, but absolutely centered upon his own silly self. If anything could have driven me from Gladys, it would have been the thought of such a father-in-law. I am convinced that he really believed in his heart that I came round to the Chestnuts three days a week for the pleasure of his company, and very especially to hear his views upon bimetallism, a subject upon which he was by way of being an authority. For an hour or more that evening I listened to his monotonous chirrup about bad money driving out good, the token value of silver, the depreciation of the rupee, and the true standards of exchange. "Suppose," he cried with feeble violence, "that all the debts in the world were called up simultaneously, and immediate payment insisted upon,—what under our present conditions would happen then?" I gave the self-evident answer that I should be a ruined man, upon which he jumped from his chair, reproved me for my habitual levity, which made it impossible for him to discuss any reasonable subject in my presence, and bounced off out of the room to dress for a Masonic meeting. At last I was alone with Gladys, and the moment of Fate had come! All that evening I had felt like the soldier who awaits the signal which will send him on a forlorn hope; hope of victory and fear of repulse alternating in his mind. She sat with that proud, delicate profile of hers outlined against the red curtain. How beautiful she was! And yet how aloof! We had been friends, quite good friends; but never could I get beyond the same comradeship which I might have established with one of my fellow-reporters upon the Gazette,—perfectly frank, perfectly kindly, and perfectly unsexual. My instincts are all against a woman being too frank and at her ease with me. It is no compliment to a man. Where the real sex feeling begins, timidity and distrust are its companions, heritage from old wicked days when love and violence went often hand in hand. The bent head, the averted eye, the faltering voice, the wincing figure—these, and not the unshrinking gaze and frank reply, are the true signals of passion. Even in my short life I had learned as much as that—or had inherited it in that race memory which we call instinct. Gladys was full of every womanly quality. Some judged her to be cold and hard; but such a thought was treason. That delicately bronzed skin, almost oriental in its coloring, that raven hair, the large liquid eyes, the full but exquisite lips,—all the stigmata of passion were there. But I was sadly conscious that up to now I had never found the secret of drawing it forth. However, come what might, I should have done with suspense and bring matters to a head to-night. She could but refuse me, and better be a repulsed lover than an accepted brother. So far my thoughts had carried me, and I was about to break the long and uneasy silence, when two critical, dark eyes looked round at me, and the proud head was shaken in smiling reproof. "I have a presentiment that you are going to propose, Ned. I do wish you wouldn't; for things are so much nicer as they are." I drew my chair a little nearer. "Now, how did you know that I was going to propose?" I asked in genuine wonder."Don't women always know? Do you suppose any woman in the world was ever taken unawares? But—oh, Ned, our friendship has been so good and so pleasant! What a pity to spoil it! Don't you feel how splendid it is that a young man and a young woman should be able to talk face to face as we have talked?" "I don't know, Gladys. You see, I can talk face to face with—with the station-master." I can't imagine how that official came into the matter; but in he trotted, and set us both laughing. "That does not satisfy me in the least. I want my arms round you, and your head on my breast, and—oh, Gladys, I want——"

Harriet Elisabeth Beecher Stowe was born in Litchfield, Connecticut, on June 14th 1811. Over the course of her Life Harriet wrote more than twenty books including travel memoirs and collections of letters and articles. Her stand out work is undoubtedly 'Uncle Tom's Cabin' about the life of African Americans under slavery. It reached millions as both a book and a play and was influential in setting both the tone and the agenda for anti slavery forces in the North and for unyielding anger in the South. When she was invited to the White House by Lincoln he is rumoured to have said "e;so you are the little woman who wrote the book that started this great war."e; In the 1870s, Stowe's brother, Henry Ward, also an abolitionist, was accused of adultery and a national scandal ensured. Harriet fled to Florida unable to bear the attacks on her brother, who she believed innocent. Harriet was among the founders of the Hartford Art School, which later became part of the University of Hartford. She was also influential in the call for women to have a better standing in society and considered the cause as just as necessary as the abolition of slavery. With the death of her husband Calvin Stowe in 1886, after a half century together, Harriet's own health started to decline rapidly. By 1888 it was reported in The Washington Post that due to dementia she had started "e;writing Uncle Tom's Cabin over again. She imagined that she was engaged in the original composition, and for several hours every day she industriously inscribed long passages of the book, almost word for word, unconsciously from memory, the authoress imagining that she composed the matter as she went along. To her diseased mind the story was brand new and she frequently exhausted herself with labor which she regarded as freshly created."e; Harriet Beecher Stowe died on July 1, 1896, at age eighty-five in Hartford, Connecticut. She is buried in the historic cemetery at Phillips Academy in Andover, Massachusetts.

The life of William Shakespeare, arguably the most significant figure in the Western literary canon, is relatively unknown. Shakespeare was born in Stratford-upon-Avon in 1565, possibly on the 23rd April, St. George's Day, and baptised there on 26th April. Little is known of his education and the first firm facts to his life relate to his marriage, aged 18, to Anne Hathaway, who was 26 and from the nearby village of Shottery. Anne gave birth to their first son six months later. Shakespeare's first play, The Comedy of Errors began a procession of real heavyweights that were to emanate from his pen in a career of just over twenty years in which 37 plays were written and his reputation forever established. This early skill was recognised by many and by 1594 the Lord Chamberlain's Men were performing his works. With the advantage of Shakespeare's progressive writing they rapidly became London's leading company of players, affording him more exposure and, following the death of Queen Elizabeth in 1603, a royal patent by the new king, James I, at which point they changed their name to the King's Men. By 1598, and despite efforts to pirate his work, Shakespeare's name was well known and had become a selling point in its own right on title pages. No plays are attributed to Shakespeare after 1613, and the last few plays he wrote before this time were in collaboration with other writers, one of whom is likely to be John Fletcher who succeeded him as the house playwright for the King's Men. William Shakespeare died two months later on April 23rd, 1616, survived by his wife, two daughters and a legacy of writing that none have since yet eclipsed.

If ever a writer needed an introduction Arthur Conan Doyle would not be considered that man. After all, Sherlock Holmes is perhaps the foremost literary detective of any age. Add to this canon his stories of science fiction and his poems, his historical novels, his plays, his political campaigning, his efforts in establishing a Court of Appeal and there is little room for anything else. Except he was also an exceptional writer of short stories of the horrific and macabre. Something very different from what you might expect. Born in Arthur Conan Doyle was born on 22 May 1859 at 11 Picardy Place, Edinburgh, Scotland. From 1876 - 1881 he studied medicine at the University of Edinburgh following which he was employed as a doctor on the Greenland whaler Hope of Peterhead in 1880 and, after his graduation, as a ship's surgeon on the SS Mayumba during a voyage to the West African coast in 1881. Arriving in Portsmouth in June of that year with less than GBP10 (GBP700 today) to his name, he set up a medical practice at 1 Bush Villas in Elm Grove, Southsea. The practice was initially not very successful. While waiting for patients, Conan Doyle again began writing stories and composed his first novel The Mystery of Cloomber. Although he continued to study and practice medicine his career was now firmly set as a writer. And thereafter great works continued to pour out of him.

Francis Beaumont was born in 1584 near the small Leicestershire village of Thringstone. Unfortunately precise records of much of his short life do not exist.The first date we can give for his education is at age 13 when he begins at Broadgates Hall (now Pembroke College, Oxford). Sadly, his father died the following year, 1598. Beaumont left university without a degree and entered the Inner Temple in London in 1600. A career choice of Law taken previously by his father.The information to hand is confident that Beaumont's career in law was short-lived. He was quickly attracted to the theatre and soon became first an admirer and then a student of poet and playwright Ben Jonson. Jonson at this time was a cultural behemoth; very talented and a life full of volatility that included frequent brushes with the authorities.Beaumont's first work was Salmacis and Hermaphroditus, it debuted in 1602.By 1605, Beaumont had written commendatory verses to Volpone one of Ben Jonson's masterpieces.His solo playwriting career was limited. Apart from his poetry there were only two; The Knight of the Burning Pestle was first performed by the Children of the Blackfriars company in 1607. The audience however was distinctly unimpressed.The Masque of the Gentlemen of Grays-Inne and the Inner-Temple was written for part of the wedding festivities for the Princess Elizabeth, daughter of King James I and Frederick V, Elector Palatine. It was performed on 20 February 1613 in the Banqueting House at Whitehall Palace.By that point his collaboration with John Fletcher, which was to cover approximately 15 plays together with further works later revised by Philip Massinger, was about to end after his stroke and death later that year.That collaboration is seen as one of the most significant and fruitful of the English theatre.

Nicholas Rowe was born in Little Barford, Bedfordshire, England, on June 20th, 1674. He was educated at Highgate School, and then at Westminster School under the tutelage of Dr. Busby.In 1688, Rowe became a King's Scholar, and then in 1691 gained entrance into Middle Temple. This was his father's decision (he was a barrister) who felt that his son had made sufficient progress to study law. While at Middle Temple, he decided that studying law was easier if seen as a system of rational government and impartial justice and not as a series of precedents, or collection of positive precepts.On his father's death, when he was nineteen, he became the master of a large estate and an independent fortune. His future path now was to ignore law and write poetry with a view to eventually writing plays.The Ambitious Stepmother, Rowe's first play, produced in 1700 at Lincoln's Inn Fields by Thomas Betterton and set in Persepolis, was well received. This was followed in 1701 by Tamerlane. In this play the conqueror Timur represented William III, and Louis XIV is denounced as Bajazet. It was for many years regularly acted on the anniversary of William's landing at Torbay. In 1704, he tried his hand at comedy, with The Biter at Lincoln's Inn Fields. The play is said to have amused no one except the author, and Rowe returned to tragedy in Ulysses (1706). For Johnson, this play was to share the fate of many such plays based on mythological heroes, as, "e;We have been too early acquainted with the poetical heroes to expect any pleasure from their revival"e;The Royal Convert (1707) dealt with the persecutions endured by Aribert, son of Hengist and the Christian maiden Ethelinda. The story was set in England in an obscure and barbarous age. Rodogune was a tragic character, of high spirit and violent passions, yet with a wicked with a soul that would have been heroic if it had been virtuous.Rowe is however well known for his work on Shakespeare's plays. He published the first 18th century edition of Shakespeare in six volumes in 1709. His practical knowledge of the stage helped him divide the plays into scenes and acts, with entrances and exits of the players noted. The spelling of names was normalized and each play prefixed with a dramatis personae. This 1709 edition was also the first to be illustrated, a frontispiece engraving being provided for each play. Unfortunately, Rowe based his text on the discredited Fourth Folio, a failing which many succeeding him also followed.Rowe also wrote a short biography of William Shakespeare, entitled, Some Account of the Life of Mr. William Shakespeare.In Dublin in 1712 a revival of his earlier play, Tamerlane, at a time when political passions were running high, the performance provoked a serious riot.The Tragedy of Jane Shore, played at Drury Lane with Mrs Oldfield in the title role in 1714. It ran for nineteen nights, and kept the stage longer than any other of Rowe's works. In the play, which consists chiefly of domestic scenes and private distress, the wife is forgiven because she repents, and the husband is honoured because he forgives.Whilst his plays met with little success at the time his poems were received extremely well. Although he was not prolific nor his output large the quality was high. With the accession to the throne of George I he was made a surveyor of customs, and then, in 1715, he succeeded Nahum Tate as poet laureate. It was the high point of his artistic life.He was also appointed clerk of the council to the Prince of Wales, and in 1718 was nominated by Lord Chancellor Parker as clerk of the presentations in Chancery. Nicholas Rowe died on December 6th, 1718, and was buried in Westminster Abbey.Rowe married first a daughter of a Mr Parsons and left a son John. By his second wife Anne, nee Devenish, he had a daughter Charlotte.
