"sponge") who shared a stage career with Haywood, and they collaborated on an adaptation of The Tragedy of Tragedies by Henry Fielding (with whom she also collaborated) and an opera, The Opera of Operas; or, Tom Thumb the Great (1733). They also may have collaborated on a translation of Claude Prosper Jolyot de Crébillon's Le Sopha in 1742. Hatchett has even been seen as the father of Haywood's second child (based on Pope's reference to "a Bookseller" as a father of one of her children, though Hatchett was not a bookseller.) No clear evidence supporting this or a domestic partnership is extant. Haywood's long writing career began in 1719 with the first instalment of Love in Excess, a novel, and ended in the year she died with the conduct books The Wife and The Husband and contributions to the biweekly periodical The Young Lady. She wrote in almost every genre, often anonymously. Haywood is now considered "the foremost female 'author by profession' and businesswoman of the first half of the eighteenth century", tireless and prolific in her endeavours as an author, poet, playwright, periodical writer and editor, and publisher. During the early 1720s, "Mrs Haywood" dominated the novel market in London, so much so that contemporary Henry Fielding created a comic character, "Mrs. Novel", in The Author's Farce, modelled after her. Haywood fell ill in October 1755 and died on 25 February 1756, actively publishing up to her death. She was buried in Saint Margaret's Church near Westminster Abbey in an unmarked grave in the churchyard. For unknown reasons, her burial was delayed by about a week and her death duties remain unpaid. Acting and drama Haywood began her acting career in 1715 at the Smock Alley Theatre in Dublin. Public records for this year list her as "Mrs. Haywood," appearing in Thomas Shadwell's Shakespeare adaptation, Timon of Athens; or, The Man-Hater. By 1717, she had moved to Lincoln's Inn Fields, where she worked for John Rich. Rich had her rewrite a play called The Fair Captive. The play only ran for three nights (to the author's benefit), but Rich added a fourth night as a benefit for the second author, Haywood. In 1723, her first play, A Wife to be Let, was staged. In the later 1720s, Haywood continued acting, moving over to the Haymarket Theatre to join Henry Fielding in the opposition plays of the 1730s. In 1729,
