Forty-two-year-old Lady Augusta (Gus) Colebrook and her twin sister, Lady Julia, are far from the “useless old maids” Regency high society has deemed them to be. Under the guise of their own social invisibility, they set out to protect women and children ignored by society and the law. But their adventures alongside the disgraced Lord Evan Belford have become increasingly dangerous.
When the twins’ activities attract the interest of Mr. Whitmore, the head of the government’s new intelligence organization, he offers them a deal. Their mission: to retrieve a noblewoman from Napoleon’s France. The reward: a full royal pardon for Lord Evan, and with it, the possibility of a life together for him and Gus.
With trepidation, Gus, Julia, Lord Evan, and government agent Mr. Kent head to Paris, the enemy’s heartland, and step into the treacherous world of spies, assassins, and bitter police rivalries. As secrets abound and catastrophic tensions rise within the group, so too does the peril from the new Paris police unit, the Sûreté, and the deadly threat from an old enemy. Will they retrieve the noblewoman in time, or will prejudice and distrust tear the group apart and leave them all in the path of destruction?
The series
In an age when a lady’s worth is measured by her silence and obedience, two middle‑aged sisters choose to make noise instead. Set against the polished drawing rooms and shadowed backstreets of Regency England, this series follows Lady Augusta “Gus” Colebrook and her twin sister Julia as they transform their invisibility as unmarried women into their greatest weapon. Outwardly, they are genteel spinsters. Privately, they are relentless rescuers, unearthing scandals, freeing the oppressed, and confronting a society that prefers its women powerless.
Read full series description
Each installment reads like an intricate web of mysteries, with clandestine rescues, dark secrets hidden behind gilded doors, and moral dilemmas that blur the line between justice and revenge. Yet at the heart of these adventures is a deeply human story: two women navigating grief, faith, and aging in a world that dismisses them, discovering that reinvention can be an act of quiet rebellion. Their bond is as fierce as their cause, tempered by sharp wit, unflinching courage, and the occasional dangerous alliance, including one with a disgraced nobleman whose presence tests both their convictions and their hearts.
With its textured world‑building, biting social commentary, and unapologetically feminist undercurrent, this series blends the intrigue of a historical mystery with the pulse of a thriller. It captures the grit beneath Regency elegance, giving voice to women who refuse to stay in their place. The result is a story that lingers, rich with danger, daring, and the quiet satisfaction of watching the underestimated upend the rules of their time.
