Talking of which, I do not remember the heyday of Inspector Morse - I suspect it fell in that happy period when I did not own a television.
Watching it today, I just don't believe in Morse as a character. By contrast, Whatley's Lewis - a working-class copper who gets promotion late in his career and finds he is brighter than he realised - seems to me entirely credible.
Yet neither of them are among the two most memorable characters from the whole Morse/Lewis/Endeavour shebang.
The first is Fred Thursday from Endeavour, played by the might Roger Allam. The second, at least before we got rather tired of Lewis as a series, is the mysterious James Hathaway, played by Laurence Fox.
My hope is that the next series in this franchise will see Hathaway steal a time machine and meet Thursday. The two of them could then travel through time and space solving crimes.
That is unlikely, but there is good news: Endeavour will return next year. Which is just as well, as we have left Thursday fighting for his life and the young Morse in the hoosegow since that last, gruelling episode.
The ITV press release does not mention Roger Allam - I suspect they are playing with us.
But what it does say is intriguing:
Our next quartet of mysteries will take the audience on a psychedelic Summer of Love fairground ride, filled with twists and turns, shrieks and scares. In particular, one encounter at a certain stately home will echo down the years, and have consequences that not even Endeavour Morse could have foreseen.My guess is that means the young Morse introduces Hathaway's parents.
