Ashley Gardner Books in Order

Where to Begin: The Recommended Reading Path

If you are new to Ashley Gardner’s historical mysteries, the absolute best place to start is with the Captain Lacey Regency Mysteries, beginning with The Hanover Square Affair. This series represents her most expansive, award-winning work and showcases her ability to blend gritty historical realities with deep, character-driven mysteries. For those who prefer a classical setting, the Leonidas the Gladiator Mysteries offer a parallel entry point set in Ancient Rome, starting with the novel Blood of a Gladiator.

While the Captain Lacey books are mysteries at their core, they follow a continuous emotional and social arc. Gabriel Lacey's personal struggles, his changing financial situations, and his evolving relationships with characters like the underworld kingpin James Denis or his companion Marianne develop significantly from book to book. Reading them in order of publication ensures you do not spoil the dramatic shifts in Lacey's life.

The Captain Lacey Regency Mysteries: Publication & Chronological Order

Leonidas the Gladiator Mysteries: Chronological Twist

Set in Ancient Rome during the transition of power, this series features Leonidas, a freed gladiator, and Cassia, a clever scribe. Unlike the Captain Lacey series, the publication order for the Leonidas books does not perfectly align with the internal chronology. The first novella, Blood Debts, was published in 2017. However, the events of the full-length novel Blood of a Gladiator (2020) actually occur first, serving as the true origin story of how Leonidas and Cassia met.

For the best experience, read the Leonidas series in chronological order:

1. Blood of a Gladiator (Book 1) - Introduces Leonidas as he tries to build a quiet life in Rome, only to be dragged into a murder investigation.
2. Blood Debts (Book 1.5 Novella) - A shorter adventure following the events of the first novel, focusing on debts and family honor.
3. A Gladiator's Tale (Book 2) - Leonidas and Cassia investigate a deadly conspiracy involving Rome's elite and the games.
4. The Ring that Caesar Wore (Book 3) - The duo searches for a legendary ring, navigating ancient relics and modern betrayals.

Robert Archer Paranormal Mysteries & Standalones

Writing under her primary pseudonym Ashley Gardner, the author also created the Robert Archer Paranormal Mysteries. This series introduces a supernatural twist to her signature Regency settings. Set in an alternate 19th-century England where shapeshifters and vampires live alongside humans, the series stars Robert Archer, a Waterloo veteran who solves crimes with paranormal undercurrents.

• A Matter of Honor (2023) - The first story introduces Robert Archer as he is pulled into a world of night-slayers and ancient debts.
• A Matter at New Year's (2024) - Archer assists a pack of were-beasts to clear their names of a local murder.

Additionally, Gardner has published standalone novels and short story collections like Murder Most Historical (2015) and Past Crimes (2017), which compile shorter mysteries and offer excellent quick reads for fans of her historical detail.

What to Know Before You Start

Ashley Gardner is the pen name of Jennifer Ashley, a highly prolific and bestselling author who also writes historical romance (including the popular Shifters Unbound and Mackenzies series) under her real name. She adopted the Gardner pseudonym specifically for her historical mysteries to distinguish them from her romance novels.

A key aspect of Gardner's work is the historical accuracy. Whether detailing the class divides of Regency London or the daily struggles of a freed gladiator in Rome's Subura, she relies on deep research to bring the settings to life. Her characters are often deeply flawed and carry physical or emotional trauma—such as Gabriel Lacey's battle wounds and depression—making their journeys feel incredibly realistic and emotionally satisfying.
