If you loved how Ada’s logic and Mary’s curiosity led them through interviews, red herrings, and a final reveal in The Case of the Missing Moonstone, you’ll click with Candice and Brandon as they decode a mysterious letter found in an attic, trace a decades-old injustice, and follow a breadcrumb trail of ciphers across their town. The stakes rise with every clue, and like Ada and Mary’s casework, the solution hinges on sharp observation and piecing together history as evidence.

Enjoyed how Ada and Mary form their own agency despite the rules of Regency society? Enola Holmes does the same in The Case of the Missing Marquess, slipping past her famous brother Sherlock’s plans and launching her own investigation. Like the Wollstonecraft girls, Enola leans on disguise, keen observation, and quick thinking to track a runaway lord through London’s streets—and proves, as Ada and Mary do, that a determined girl can crack a case others overlook.

If the sparkling banter and cheeky asides in The Case of the Missing Moonstone made you grin, Penelope Lumley’s escapades at Ashton Place will hit the same sweet spot. With prim yet playful narration, delightful turns of phrase, and farcical set pieces, Penelope wrangles three feral children while uncovering house secrets—much like Ada and Mary’s humorous scrapes as they sneak about London, test wild hypotheses, and keep their propriety (mostly) intact.

If you were charmed by the way Ada’s cool logic balances Mary’s imaginative leaps, you’ll love Daisy Wells and Hazel Wong at Deepdean School. In Murder Most Unladylike, the pair clash, compromise, and ultimately click as they investigate a teacher’s disappearance, forming rules for their society and learning to trust each other—echoing the Wollstonecraft team’s evolving bond as their strengths mesh into a formidable partnership.

If you liked how The Case of the Missing Moonstone reimagines real figures in a slightly askew past, you’ll enjoy exploring an alternate New York built by the ingenious Morningstarr twins. Tess and Theo Biedermann and Jaime Cruz chase mechanical marvels, secret clues, and urban legends to solve a grand puzzle—offering the same blend of history-remixed worldbuilding and brainy sleuthing that powers Ada and Mary’s London adventures.
