Grantchester’s producers planned to kill off Robson Green’s character in a tear-jerking series finale of the TV drama. But in the end they got cold feet and decided viewers would prefer a happier ending.

The final series of the ITV smash – starring Robson and Rishi Nair as crime fighting duo Det Geordie Keating and The Rev Alphy Kottaram – will air in the UK next year.

But viewers in the US have already the eleventh and last-ever series and got a shock when Keating was shot and left fighting for his life. Now screenwriter Daisy Coulam has revealed how she wrestled with the idea of killing him off altogether.

Robson played a great joke as filming came to a close.

She confessed: “I mean the amount of times we tried to be like, ‘He should die. He should definitely die’. I mean he died probably about four times in the story meeting and we just couldn’t do it. It would just be too big.

“You’re like ‘No, because you need that moment at the end’. You need hope and you need joy because it’s a (platonic) love story and you need your two lovers alive at the end, I think.”

Instead fans will see Keating survive the shooting and decide to retire from the force. But he hands ‘the baton’ over to fellow officer Larry Peters (played by Bradley Hall) to carry on sleuthing with the help of The Rev for future cases.

And in a touching moment, Keating leaves his protégé his hat – which he has kept with him since the start.

Daisy added: “The hat moment … it was randomly filmed the day James Norton came to set for a little visit. We were sitting and we said to Robson ‘What kind of thing would you like to do? You know, what scene do you want?’

“And he said ‘I think you should give Larry the hat’. We were like ‘Yes’ because Emma and I are obsessed with Indiana Jones and it’s basically Indiana Jones, isn’t it? It’s ‘the putting the hat on’. So we were very happy and I just think Bradley acted his socks off and he doesn’t say anything but you really, really feel his pride. It’s so sweet.”

During filming of his final scenes on a hospital trolley Robson, 61, decided to lighten the mood. He sneaked in a sign which read ‘Available for panto’ – as the cast knew they needed to start looking for new projects now Grantchester is ending.

When the hospital porters wheeled him in and the cameras started rolling he held up the sign and made everyone burst out laughing.

Afterwards he told The Masterpiece Studio podcast: “I’m going to miss that feeling of when you look at a schedule, you’re going to a certain location. And in this case, it was Grantchester. I’d always look at the schedule and go, ‘When are we going to Grantchester?’ Because it’s like going on holiday with lots and lots of friends. That’s what I’ll miss.”

Plotlines for the final series will see The Rev Alphy question his faith in God and new fashion boutique owners Cathy Keating and Mrs C (Kacey Ainsworth and Tess Peake-Jones) get caught up in a murder.
