October Challenge - Edge of Darkness - Dark

Day 2 of the October daily challenge - Edge of Darkness

This was a TV series in the 1980's which has since been remade and also made into a film. It was a dark political thriller.

I've taken a different slant - taking a can with an emblem on it, as it disappears around the side out of view. The contents of the can are obvious if you know the emblem, and they are of course very dark.

In case you haven't recognised it, it is in fact a can of Guinness, or the edge of (a can) of dark(ness).
