The parish church seen in the episode is St Michael's at Bray, in Berkshire. The location for the imposing house where Ruth works is Dorney Court, near Windsor.
The detective novel on which this episode is based probably has the most complicated storyline of any of Colin Dexter's many books, with a string of murders, conspiracies, sub-plots, and other crimes as well.
