Brother Eadulf has become Saxmundham's most famous international fictional character, through the best-selling
Sister Fidelma mysteries by
Peter Tremayne (a pseudonym of the Celtic scholar and author Peter Berresford Ellis). Brother Eadulf, as companion and assistant to Sister Fidelma, often plays a crucial part in resolving the mystery. He is introduced as originally the hereditary gerefa (magistrate) of "Seaxmund's Ham in the land of the South Folk." He attends the famous
Synod of Whitby in AD 664 and joins Sister Fidelma in solving a murder of one of the delegates (
Absolution by Murder, 1994). He has since appeared in most of the novels and some of the short stories, although the Saxmundham area has been used as a setting in only two of the novels:
The Haunted Abbot (2002) and “The Grave of the Lawgiver” (2025). Tremayne chose Saxmundham as Eadulf's place of origin because of local connections, the nearness of the town to an ancient royal burial site of the East Angles, and the historic
East Anglian connections with Irish Christian missionaries. He appears in all but two of the Sister Fidelma series of mystery novels, set in 7th century
Ireland. The series has now reached 31 published titles, appearing in a score of languages. An International Sister Fidelma Society, devoted to the author and his work, has existed for 20 years and publishes a 20-page colour magazine three times a year. ==Listed buildings==
