Contrary to the oft-uttered phrase, you can likely tell a lot about the book you’re picking up based on the cover. For one thing, you might be able to guess at the genre. You may also have some idea of when the book was published. Over the last fifty years or so, book cover art has changed a lot. This is true across a wide mix of genres. A few years ago, we published a retrospective on the evolution of romance cover art. With the recent news that mass market paperbacks are facing extinction, we've decided to look into the cover art evolution of a few more of our favorite genres.
One of the earliest examples of a modern mystery novel is Edgar Allan Poe’s 1841 novel, The Murders in the Rue Morgue (1841), which introduced the locked room concept, where the crime takes place in a remote or enclosed environment, as well as the first fictional detective, C. Auguste Dupin, a brilliant amateur sleuth.
A few decades later, Wilkie Collins further developed this formula with his classic English mysteries, The Woman in White (1859) and The Moonstone (1868). In 1887, Arthur Conan Doyle created the beloved Sherlock Holmes, bringing massive, widespread popularity to the growing genre.
Cover art has come a long way since the so-called Golden Age of crime fiction. Popular authors of this period included a group of British women writers dubbed the Queens of the Golden Age: Dorothy Sayers, Margery Allingham, Ngaio Marsh, and, of course, Agatha Christie, who has been named the bestselling novelist of all time. Learn more about Christie in this 2020 post.
Unfortunately, many of the early covers from this era have been lost to time, but they were characterized by art highlighting the whodunit formula, including clues, country houses, and tense scenes. Art deco was a particularly popular style of some of these covers. In lieu of the originals, here are a few Golden Age mysteries that have been given gorgeous reprints paying tribute to the style of that era.
In 1939, Robert DeGraff launched pocket books, small, cheaply produced paperbacks that were easy to take everywhere. This was a game changer for the evolution of book covers.
With the popularity of these lightweight, inexpensive volumes, a book's cover became a critical selling point. Publishing houses began investing heavily in art that would stand out on the crowded racks of paperbacks for sale at corner stores, magazine stands, and airports.
With the revolution that accompanied mass market paperback craze, the decades that followed saw some of the best mystery cover art. In fact, many of the classics from earlier eras got fresh reprints with flashy new covers. These often gorgeous artworks were designed to titillate and attract a largely male readership with provocative, gritty scenes involving shapely women, guns, and the suggestion of sex and violence. Here are some stellar examples from this era:

In the 1960s and '70s, in response to the grittier, more explicit tone of hardboiled mystery fiction, a new subgenre emerged: the cozy mystery. Seen by many as an attempt to recreate the Golden Age of detective fiction, these whodunnits generally maintain a closed-door approach to sex and violence. The stories often feature an amateur sleuth and take place in quaint bucolic settings.
The cover art of the cozy mystery seeks to achieve a balance between intrigue and comfort. They may feature the prescient pet of the protagonist—a staple of the genre. Other iconography of this genre of covers include steaming coffee mugs, books, and tasty treats. Here are some excellent examples we found on our shelves. We were unable to find an artist credit for several of these covers.
In recent years, the cozification formula has been embraced by a variety of fictional genres, including fantasy and romance.
In our digital age, book cover art across the industry has taken on simpler, stylistic cover designs and larger text so that titles and images pop in a digital format. This shift has led to some gorgeous minimalist designs utilizing vibrant colors. Below are some of the recent mystery cover designs that we love. As you can see, the types of artwork represented are varied and beautiful, from bold, modern imagery to atmospheric, impressionist landscapes.
We’ve had a blast unpacking the details of the mystery cover evolution. We hope you've enjoyed it too! Check out our fantasy cover evolution post and stay tuned for science-fiction up next.
