Fredrick & Grace Mystery Books in Order

This series follows Lord Frederick Percy and Gracelynn Ferguson Astley, a newly married couple who keep stumbling into danger, theft, murder, and secrets they cannot resist untangling. Pepper D Basham mixes country-house mystery, historical romance, and light adventure here, so the books feel both cozy and lively at the same time.

The story begins with The Mistletoe Countess, where a marriage of convenience at Havensbrook Hall turns into something much more complicated once Grace finds herself trying to win Frederick's trust while also making sense of a murder. That setup matters because it gives the whole series its foundation. These books are not just about cases. They are also about a marriage growing stronger under pressure.

Grace loves fiction, and that shapes everything.

She reads people through the lens of stories, which gives the series much of its charm. Frederick is steadier, more practical, and often trying to keep up with where Grace's imagination has already gone. Together they make a fun team. Their differences create banter, but they also make them useful partners when the stakes rise. Grace notices odd details and emotional currents. Frederick brings patience, rank, and a willingness to protect the people he loves.

After the first book, the series opens outward. The Cairo Curse takes them to Egypt for a tomb, an antiquities heist, and fresh danger. The Juliet Code moves to Italy and a missing-art puzzle among masks and shifting identities. The Highland Heist sends them toward Scotland, family questions, and a castle full of buried trouble. The Bachelor Spy pushes the world toward wartime suspense, with Havensbrooke Hall turned into a convalescent hospital and espionage creeping close to home.

The tone stays readable and inviting even when the plots turn darker. Think suspicious guests, hidden passages, family secrets, stolen objects, and travel that always seems one clue away from disaster. Basham keeps the emotional thread clear, so readers who come mainly for the romance still have plenty to hold on to.

Read these in order if you can. Each mystery has its own shape, but the real pleasure is watching Frederick and Grace become more confident, more tender, and more dangerous to criminals with every book.
