Sir Geoffrey Mappestone Books in Order

The Sir Geoffrey Mappestone books, written by Susanna Gregory and Beau Riffenburgh as Simon Beaufort, begin in the wake of the First Crusade. The opening novel, Murder in the Holy City, drops Geoffrey into Jerusalem in 1100, where victory has not brought peace so much as a new round of fear, grievance, and political scrambling. That mood follows the whole series.

Geoffrey is not the usual chest-thumping crusader. He is a knight and a capable fighter, but he is also reflective, weary of pointless brutality, and often more sensible than the men above him. As the fourth son of a landed family, he was never meant to inherit much, and that slightly off-center position makes him a useful observer. He moves through noble circles, royal errands, church disputes, and family quarrels, but he is never so secure that he can ignore the danger.

He does not investigate alone for long. Roger, his friend and frequent companion, becomes an important counterweight, especially as the books shift back to England and into the politics of Henry I’s reign. Their cases involve poisoned kin, escaped bishops, murder in baronial households, trouble at the royal mints, disputed inheritances, and suspicious missions into Wales. The mysteries are tied to the way power was actually held in the early twelfth century, through land, loyalty, blood, and church influence.

Safety is usually temporary.

The setting is one of the pleasures. The series begins with crusader states and the aftershocks of conquest, then opens into Herefordshire, Durham, Bristol, Bath, the south coast, and the Welsh borderlands. Everywhere Geoffrey goes, the Norman Conquest still feels recent. Old resentments between Normans and Saxons simmer. Barons test the king. Bishops act like princes. A marriage can be political strategy, and a private feud can quickly become a national problem.

These books have more open adventure than Gregory’s solo Cambridge novels. There are journeys, storms, military baggage, fortresses, and royal messages carried over rough country. But the appeal is not just movement. Like her other work, this series pays attention to institutions and to the people trapped inside them. Geoffrey has to navigate courts, households, abbeys, and castles where everyone has a grievance and several people have a knife.

Because the series grows out of a real place, Goodrich Castle, it also has a nice sense of rootedness. Geoffrey’s family history, his uneasy connection to home, and the question of what kind of life he actually wants give the books a through-line beyond the individual murders.

If you like historical mysteries that mix knightly adventure with grounded politics, Sir Geoffrey Mappestone is a strong choice. It offers battles and barons, yes, but also a clear-eyed sense that the hardest problems are usually human ones, greed, inheritance, ambition, and fear.
