AgProv's made it sound like a Noir plot.

'
The world-weary laughter of that two-bit dame Mary...'
Now there's an idea.
Somebody like Jo Nesbo or Leif G.W. Persson re-writing the Gospels and setting the action in Stockholm or Oslo. I'm now imagining Harry Hole as a cynical but competent maverick centurion, maybe with too much of a reliance on the issue wine ration, who is conflicted by finding this immigrant from the Middle East, Joshua something, to be a sympathetic guy and personally likable, but surrounded by shady characters, including those fanatical types Security want me to keep an eye on. This Judas guy has a profile that lights all the red bulbs.
Centurion Hole then notes a junior copper who is paralysed in hospital suddenly makes a miraculous remission. He is also impressed that booze appears in his bar where previously there was only water.
At the end, Hole plays the Longinus role at the death of the immigrant; afterwards, he maybe glimpses him around Oslo a few times when the guy is at least three days dead, and puts it down to the akavit.
As for the Persson version set in Stockholm... this involves the loathsome copper Evert Bäckström, a man who isn't so much racist as utterly misanthropic and certainly xenophobic towards immigrants. Given the brief by Security to organise surveillance of this group of religiously-motivated fanatics who are preaching in Stockholm and gathering support, Bäckström takes the route of pulling in a close comrade known to have terrorist leanings (or more so, by the standards of those bloody immigrants Sweden's letting in from the Middle East, everybody knows they're
all terrorists and fanatics) , and beating up this Judas guy until he agrees to act as the mole in the organisation; thirty krone a time becomes the agreed informant fee for regular reports....
After a junior copper gets his ear sliced off in a confrontation by night in a public park, Bäckström then goes mediaeval on this other associate, who repeatedly denies he knows the Person of Interest.
The Danish version might have Mary Magdalene in a big shapeless woolly jumper, a woman with personality issues...
The Bible as Scandi Noir. This has potential!
