Aside from her two popular series of historical mysteries, featuring Matthew Bartholomew and Thomas Chaloner, she is also a member of the Medieval Murderers, a group of writers who give talks and presentations at literary festivals, as well as writing books together, and has written a number of non-fiction books. She and her husband live in a village near Cambridge.
