Sworn to God: An exciting historical thriller based on real events

Yorkshire, AD 1329
A new religious group moves into an abandoned church just north of the village of Altofts, but when men start dying under strange and suspicious circumstances the local bailiff decides to investigate.
The Disciples of God and their charismatic leader, Lady Alice de Staynton, appear truly holy, but something sinister seems to be going on within the walls of the newly refurbished St Joseph's. Certainly the bailiff, John Little, has his suspicions about some of the warrior-like male acolytes, but are his fears justified? Infiltrating the group seems to be the best course of action, although the volatile Will Scaflock is none too happy about being nominated for the job by Friar Tuck...
