Agatha Christie is undoubtedly the most famous author of the ‘Golden Age of Crime Fiction’ (or indeed the most famous crime author of all time). She did not stand alone, however, but rather was part of a closely connected network of crime writers who worked in Britain and the rest of the Empire between the two wars. Some of the more illustrious authors organised themselves in the Detection Club, a group which was founded in the 1930s and still exists today. One of the founding members of the Detection Club was Dorothy L. Sayers, another female crime fiction writer who obtained widespread recognition during the 1920s and 1930s.
Sayers was born in 1893 in Oxford to a well-to-do couple; her father was a reverend and chaplain to Christ Church Cathedral in the city. Sayers herself studied at Somerville, the all-female College of the University of Oxford. She was there from 1912 to 1915, leaving before the arrival of Vera Brittain and, later, Winifred Holtby. At Sommerville Sayers would also meet Muriel Jaeger, who eventually established her own literary career. Sayers would later draw heavily on her experiences at Somerville for the crime novel Gaudy Night, which appeared in 1935.
After completing her degree, Sayers moved to London and briefly took up a teaching post: teaching was one of the career paths young women were strongly encouraged to enter into, with its associations of helping, caring and other supposedly typical feminine traits. After the teaching stint, she briefly returned to Oxford and then travelled to France, only to eventually return again to London and take up a job as a copywriter. She never lost sight of her literary ambitions and some time in 1920 she started to come up with the amateur detective who would become her most famous character: Lord Peter Wimsey.
Eventually, Sayers published eleven Wimsey novels as well as a series of short stories in which he featured. It can be argued that in Wimsey, Sayers created an ideal man, and part of the fun of the Wimsey stories lies in the interplay between their plots and Sayers’ private life. Wimsey is an aristocrat, the second son of the Dowager Duchess of Denver. He has a private income, a very steady butler named Bunter, an MA from Oxford and an interest in collecting rare books. He also appears to work for the British government on occasion, as he is sent across Europe to undertake diplomatic missions to try and avoid war. He is close friends with detective Charles Parker of the Metropolitan Police, who later in the series marries Wimsey’s sister. Wimsey’s intellect, financial independence, links with the police and elevated status in society make him the ideal amateur sleuth, as he has the means and ability to enter almost any situation.
In Strong Poison, the fifth Wimsey novel, Sayers started to really draw on her own life for the book’s plot. Although all the Wimsey novels contain intricately plotted crime puzzles which adhere to the rules of ‘fair play’, its in the interpersonal relationships of the characters where the clues are to Sayers’ private life. In the early 1920s, Sayers had a relationship with fellow writer John Cournos, which came to an end when Cournos wanted to sleep together outside of the marriage, which Sayers did not want. In Strong Poison, Sayers introduces Harriet Vane, a clear alter-ego for herself. Vane is a crime fiction author who is on trial for the murder of her partner; in this fictional relationship the question of sex outside of marriage was also paramount. The victim in Strong Poison is clearly meant to be a stand-in for Cournos, and Sayers no doubt got great satisfaction from giving the character an extremely painful death from arsenic poisoning.
Wimsey falls in love with Harriet Vane in Strong Poison, and throughout the remainder of the Wimsey series their relationship takes on increased importance until, in the aforementioned Gaudy Night, Harriet feels that Peter is ready to enter into marriage on equal terms. In Sayers’ real life, no such happy ending was forthcoming. Shortly after the end of her relationship with Cournos, she met Bill White, a man who later turned out to be already married. By the time Sayers found that out, however, she had already agreed to a sexual relationship with him and she found herself pregnant in 1923. Sayers never even told her parents about her pregnancy, so convinced was she that they would not be able to accept it. Amazingly, though, Bill White’s wife came to her aid. Sayers gave birth to her son, John Anthony, in complete secret during a brief leave of absence from her copywriting job. Bill White’s wife, Beatrice, made arrangements for the birth. John Anthony grew up in a foster home run by Sayers’ cousin; during her lifetime Sayers only revealed his existence to five people and never told her parents they had a grandchild.
Aside from the Wimsey novels and stories, Sayers was a prolific reviewer of crime fiction and also contributed to several volumes written by a group of Detection Club members. The last full Wimsey novel, Busman’s Honeymoon, appeared in 1937. After this, Sayers mostly turned her attention to religious work, such as a translation of Dante’s Divine Comedy.  She remained a key member of the Detection Club until her death in 1957. Her books remain in print and have been adapted for the screen several times.
