i then remembered that the INTERLAKEN 'budget hotel' was called THE HIRSCHEN...and i looked it up in 'images' upon a NORTON safe search...and realised:

Have I just come across the MOONS?

look at those BLACK images of silhouetted people. Yes one can see that they were all 'tricked' into sitting for portraits...and I 'know' that this was an 'intelligence' number in order to identify them later on...but I cannot remember which 'intelligence agency' set it up...probably the whole lot of them, involved at that time...

The EURO site contains the image of the HIRSCHEN.
