Feardorcha Phelan. Feardorcha is an Irish name: from the Gaelic words fear (meaning man) and dorcha (meaning dark or dark-haired) . Phelan is an Irish surname: from the Gaelic for "wolf."
This episode reveals that Inspector Robbie Lewis may actually be much more open-minded than previously assumed by the audience, and Hathaway.
David Ryall, whom Lewis meets on the allotment, starred as the driving instructor in the Morse episode 'Driven to Distraction'.
A scene near the end is set in Jericho, the same setting as The Dead of Jericho (1987), the pilot episode of that series.
Nova Rose tells Lewis that hanging was abolished in 1964. The last people to be executed in England were hanged in 1964. Hanging was suspended in 1965 and was eventually abolished in 1969.
