Welcome to the secret life of the Colebrook twins: unnoticed old maids to most, but unseen champions to those in need - society be damned.

Lady Augusta Colebrook, 'Gus', is determinedly unmarried, bored by society life, and tired of being dismissed at the age of forty-two. She and her twin sister, Julia, who is grieving her dead betrothed, need a distraction. One soon presents itself: to rescue their friend's goddaughter, Caroline, from her violent husband.

The sisters set out to Caroline's country estate with a plan, but their carriage is accosted by a highwayman. In the scuffle, Gus accidentally shoots the ruffian, only to discover he is Lord Evan Belford, an acquaintance from their past who was charged with murder and exiled to Australia twenty years ago. With Lord Evan injured and unconscious, the sisters have no choice but to bring him on their mission to save Caroline. What follows is a high adventure full of danger, clever improvisation, heart-racing near misses, and a little help from a revived and rather charming Lord Evan.

And so begin the beguiling adventures of the Colebrook twins ...

'Goodman's ladies are the undercover Regency heroes we've been waiting for! This is sparkling, thrilling, romantic fun.' Toni Jordan

'Heroines can appear out of nowhere and soon become indispensable, and such is the case with Lady Augusta Colebrook, who, with her twin sister Lady Julia, is at the heart of this compelling, enthralling, unforgettable novel. You will be very glad you've let Gus into your life then wonder how you ever did without her.' Sophie Green

'Such an unexpected book. A Regency romp, like a 21st-century Georgette Heyer, with gay characters, people of colour and a feisty and independent heroine in her 40s. Just wonderful and delicious.' Maggie Alderson

'Fresh and fearless, Alison Goodman's exquisitely written, impeccably researched genre-blending novel shines a light in the darkest corners of Regency England. The Benevolent Society of Ill-Mannered Ladies is part heart-racing adventure, part gothic mystery, part tantalizing romance, and wholly wonderful. I can't wait for the next instalment!' Joanna Lowell, author of Artfully Yours

'A truly delightful feminist adventure story that will have you cheering on the unconventional Colebrook sisters in all their exploits.' Stephanie Marie Thornton, USA Today bestselling author of Her Lost Words
