Dorothy L. Sayers (1893-1957) was a playwright, scholar, and acclaimed author of mysteries, best known for her books starring the gentleman sleuth Lord Peter Wimsey.

Born in Oxford, England, Sayers, whose father was a reverend, grew up in the Bluntisham rectory and won a scholarship to Oxford University where she studied modern languages and worked at the publishing house Blackwell's, which published her first book of poetry in 1916.

Years later, working as an advertising copywriter, Sayers began work on Whose Body?, a mystery novel featuring dapper detective Lord Peter Wimsey. Over the next two decades, Sayers published ten more Wimsey novels and several short stories, crafting a character whose complexity was unusual for the mystery novels of the time.

In 1936, Sayers brought Lord Peter Wimsey to the stage in a production of Busman's Honeymoon, a story which she would publish as a novel the following year. The play was so successful that she gave up mystery writing to focus on the stage, producing a series of religious works culminating in The Man Born to Be King (1941) a radio drama about the life of Jesus.

She also wrote theological essays and criticism during and after World War II, and in 1949 published the first volume of a translation of Dante's Divine Comedy (which she considered to be her best work).

Dorothy Sayers died of a heart attack in 1957.
