Thanks Elsa, John and Anirban. The shot would have been a case for the D800. Since it is highly cropped, there is not Michael detail to be found on the man's face, so better leave it in the dark. His wristwatch is quite conspicuous and becomes the main subject (and the title could become "ultima necat"). The buildings on that bank are quite old and especially survived the 1st WW, which destroyed half of the city.
I've read several books by Simenon, most of them at a hospital (maybe the only proper literature available there). Loners were among his favorite subjects indeed, but I tend to associate him with Paris. If that had been shot at Île saint Louis, maybe...
