Karen Haden

Karen Haden is a British historical crime novelist whose work focuses on the religious, political and intelligence struggles of late Tudor and early Stuart England. Born and raised in Portsmouth, she studied engineering before moving into technical and consultancy work, including around fifteen years working with intelligence and cyber-security agencies. That background strongly influences her fiction, which is concerned with surveillance, misinformation, espionage and the ways new technologies can destabilise political authority. Haden has compared the impact of the early modern printing press with that of the modern internet and social media. Her novels also deliberately look beyond courts and ministers to the lives of ordinary people affected by religious persecution, crime and political change.

Her Alexander Baxby Mysteries follow a fictional physician drawn into murder investigations and espionage during the early seventeenth century. Paying in Blood (2024) begins around the Battle of Nieuwpoort in 1600 and later moves through Lincolnshire and London during the transition from Elizabeth I to James I; it was longlisted for the Aspects of History Spymasters Award. Naming the Dead (2025) continues the story in Amsterdam in 1608, where Baxby becomes involved in investigating the deaths of English exiles against the background of religious migration, Anglo-Dutch rivalry and the approaching Twelve Years’ Truce. A third novel is planned to return Baxby to England and bring the series forward to 1613, around the marriage of Princess Elizabeth, daughter of James I, to Frederick V of the Palatinate. Across the series Haden combines historical crime with political and religious intrigue, early intelligence networks and real figures connected with the Separatist and early Baptist movements.
