I think I got a fake gendarme once. Or it might have been a real gendarme overstepping the mark.
There was the insistant, loud, banging knock on the door, "Open up, police " This was at about ten in the morning and I live in a block of flats with buzz in entry. A doorbell was available to the eejit.
He was in what looked to be legitimate uniform but as far as I know, no matter where you are, at least in Europe, they go around in twos, so I thought it was a bit strange that he was on his own.
"We are looking for a certain Dimitri."
"I don't know any Dimitris."
More strange questions with me holding the door open just enough for one of my eyes to show for a couple of minutes, mostly about how much I paid in rent.
Then he went off. I should have maybe phoned the gendarmerie to see what was going on but I couldn't be doing with it at the time.
Nothing ever came of it. A mystery.
