More info: I think it's from a Requiem - the first part is the end of an 'Agnus Dei', and after a brief pause, the words sung by the soloist are 'In paradisum deducant...'

 

This choral music in Midsummer Murders Made to Measure is also used in Endeavour! It's wonderful and uplifting.

 

It tells me "You have not provided a valid SoundCloud URL."
Can you upload it here as an mp3 or use youtube?

And just now I realize this is a nine years old request.

 

I live in the fictional county of Midsomer. It’s all filmed around here. Never go to the village fête; never go to the woods on your own; never join any hobby group; never phone someone and say you know something but you can only tell them in person. We’ve survived being here for nearly two years so far.

Someone down the road did get murdered last year, though.

 

There are at least a dozen films and TV series and several dozen books about fictional serial killers in Iceland.
Iceland’s last real serial killer Axlar Bjorn is believed to have murdered between 9 and 18 people with an axe and dumped their bodies in the pond on his farm.

He was executed in 1596.

 

This used to be a regular occurrence on TC - someone would open a new account, ask one question (usually about a piece of music which they wanted identifying) and then they'd disappear almost immediately afterwards whether the question was answered or not. I used to privately refer to them as mayflies.
