Sayers’s Lord Peter Wimsey detective novels are delightful and well-written. Her first novel is Whose Body?, so you can start there.

If you want to jump straight to a strong female character, go to Strong Poison, then Have His Carcase, and ONLY THEN, Gaudy Night.

Short story collections, such as Lord Peter Views the Body, are also a fun beginning.

Most Lord Peter materials are also available on audiobook.

Try Letters to a Diminished Church, published by W. Publishing Group. This collection includes some of her most famous essays, such as “Why Work?” and “The Dogma is the Drama.” Some of these essays can also be found online.

A powerful introduction to her poetry is Catholic Tales and Christian Songs, which is available online. As the title indicates, these are entirely inspired by her faith.

If you want a more diverse selection, including her World War II Poetry, try The Poetry of Dorothy L. Sayers, ed. by Ralph Hone.

Frankly, Wikipedia isn’t a bad place to start. You can also listen to some any of the eye-catching episodes of the Dorothy L. Sayers Podcast.

But if you want a book, Barbara Reynolds’ Dorothy L. Sayers: Her Life and Soul is a good place to start. It’s a little sappy in places, but good information.

If you want an intellectual-focused biography, try The Passionate Intellect: Dorothy L. Sayers’s Encounter with Dante, also by Reynolds.

Frankly, any biography will be good, except Janet Hitchman’s Such a Strange Lady. Avoid that until you become a Sayers scholar.

You can start with her “Lost Tools of Learning” essay, which is available in essay collections and online.

You may also want to consider The Poetry of Search and Statement: Volume Three on Dante and Other Writers, which includes essays on allegory, teaching Latin, poetry, and more.

For theology and art, you can’t do better than Mind of the Maker, which is a masterpiece.

Her letters are also incredible! They are a financial investment, but esp. Volumes 2-4 are entertaining and enlightening reading!
