Thomas Hardy was born in Dorset in 1840. His first published novel was Desperate Remedies in 1871. Such was the success of these early works, which included A Pair of Blue Eyes (1873) and Far From the Madding Crowd (1874), that he gave up his work as an architect to concentrate on his writing.

However, he had difficulty publishing Tess of the D'Urbervilles (1889) and was forced to make changes in order for it to be judged suitable for family readers. This, coupled with the stormy reaction to the negative tone of Jude the Obscure (1895), prompted Hardy to abandon writing novels altogether and he concentrated on poetry for the rest of his life. He died in January 1928.

William Wilkie Collins was born in London in 1824, the son of a successful and popular painter. On leaving school, he worked in the office of a tea merchant in the Strand before reading law as a student at Lincoln's Inn. However his real passion was for writing and, in 1850, he published his first novel, Antonina.

In 1851, the same year that he was called to the bar, he met and established a lifelong friendship with Charles Dickens. While Collins' fame rests on his best known works, The Woman in White and The Moonstone, he wrote over thirty books, as well as numerous short stories, articles and plays. He was a hugely popular writer in his lifetime. An unconventional individual, he never married but established long-term liaisons with two separate partners. He died in 1889.

Sir Arthur Conan Doyle was born in Edinburgh in 1859 and died in 1930. Within those years was crowded a variety of activity and creative work that made him an international figure and inspired the French to give him the epithet 'the good giant'.

He was the nephew of 'Dickie Doyle' the artist, and was educated at Stonyhurst, and later studied medicine at Edinburgh University, where the methods of diagnosis of one of the professors provided the idea for the methods of deduction used by Sherlock Holmes. He set up as a doctor at Southsea and it was while waiting for patients that he began to write.

His growing success as an author enabled him to give up his practice and turn his attention to other subjects. His greatest achievement was, of course, his creation of Sherlock Holmes, who soon attained international status and constantly distracted him from his other work; at one time Conan Doyle killed him but was obliged by public protest to restore him to life.

And in his creation of Dr Watson, Holmes's companion in adventure and chronicler, Conan Doyle produced not only a perfect foil for Holmes but also one of the most famous narrators in fiction.

O. Henry (1862-1910) had a short but colourful life. Born William Porter in Greensboro, North Carolina, he initially worked as a pharmacist before moving into journalism. In 1896 he was arrested for embezzling funds while working as a bookkeeper for a bank.

In a moment of madness, he absconded on his way to the courthouse before his trial and fled to Honduras for six months. He returned to face trial after learning that his wife was dying of tuberculosis and served three years in jail. While in prison, he adopted the pen name O. Henry, and after his release he found great fame and popularity as a short story writer.
