For those following the Endeavour/Morse connections: Farnleigh Open Prison will be the setting of "Absolute Conviction," and Inspector McNutt will turn up in "Masonic Mysteries." (Yes, using future tense to describe TV episodes from the early '90s!).
Still, for all these clever allusions to the original Morse series, this last episode seemed to take place in a different (and much darker) universe. It's hard to believe this series of violent and traumatic events--including Endeavour's (we assume) brief incarceration--wouldn't still lurk in Thames Valley memory twenty years or so later. (Especially in the episode where a cunning mastermind tries to frame Morse for murder). From "Neverland" on, I'm going to have to view "Endeavour" Oxford as a world distinct from "Morse" Oxford. "Neverland" was interesting for giving us more of the seamy underbelly of poor and industrial Oxford (abandoned trailers, slums, etc.); at the same time, that choice gave the episode more the flavor of current British police series than the original "Morse." Or so it seems to me. It's certainly a far cry from the cloud-cuckoo land of "Inspector Lewis."
