When we finished series 5, Davy [David Kane, the writer/executive producer of Shetland] and I thought we've probably got about two more in us, then let's wrap it up. I still don't think it's really hit me properly. I remember the very last day of filming, we were in some car park and it was very anticlimactic! But I think once this series, this version of the show, is finished, it will probably hit me then.
