The Recommended Reading Order
For the best reading experience, you should follow the publication order of the Irene Adler series. Because the series features a continuous narrative, the relationships between the characters—most notably the romance between Irene and Godfrey Norton, and the personal growth of her companion Penelope Huxleigh—develop sequentially from one book to the next. Reading them in order ensures you won't miss key character arcs or recurring plot threads.
The Complete Reading List
- Good Night, Mr. Holmes (1990) – The first novel in the series. It serves as both a prequel and a parallel narrative to Arthur Conan Doyle's classic short story "A Scandal in Bohemia," exploring Irene's early life, operatic career, and detective exploits before culminating in her famous clash of wits with Sherlock Holmes.
- Good Morning, Irene (1991) (Also published as The Adventuress) – Irene and her companion Nell Huxleigh travel to Paris, only to be drawn into a dark conspiracy involving a tattooed corpse, international politics, and a secret society.

What to Know Before You Start
The Narrator's Perspective
Unlike traditional Sherlock Holmes stories narrated by Dr. John Watson, Carole Nelson Douglas narrates these books through the eyes of Penelope "Nell" Huxleigh. A prim, proper, and deeply observant parson's daughter, Nell acts as Irene's companion, secretary, and biographer. The contrast between Irene's bold, theatrical lifestyle and Nell's conservative Victorian sensibilities provides the series with humor, warmth, and a unique female perspective on historical detective work.
Alternative Titles and Publishing History
If you are searching for physical copies or eBooks, you may encounter two different titles for books two, three, and four. The books were originally published as Good Morning, Irene, Irene at Large, and Irene's Last Waltz. They were later repackaged and published as The Adventuress, A Soul of Steel, and Another Scandal in Bohemia to emphasize their connections to Arthur Conan Doyle's universe. The content of the novels is identical, so you can read whichever edition you find first.
The Jack the Ripper Duology
While most books in the series function as standalone cases with ongoing character subplots, Chapel Noir and Castle Rouge form a single, continuous story. Chapel Noir concludes on a major cliffhanger, making it essential to have Castle Rouge ready to read immediately afterward. This duology adopts a darker, thriller-like tone compared to the lighter cozy style of the earlier books.
Historical Figures and Cameos
Douglas grounds Irene's adventures in the authentic cultural landscape of the late 19th century. Throughout her travels, Irene interacts with a variety of real historical figures. You will encounter playwright Oscar Wilde, actress Sarah Bernhardt, author Bram Stoker, and pioneering investigative journalist Nellie Bly (who plays a significant role in Castle Rouge and Spider Dance).
