July 2013

I dedicate July 2013 to my dear friend Dave Joyce, who took his own life during this most beautiful of summer months. He had been suffering from anxiety and depression for some time and despite much help from friends, family and most of all his sister Alison, Dave must have felt that he could not carry on. The photograph above shows Dave walking along the pebbly beach at Branscombe, heading towards the dramatic Hooken Cliffs. I took this photograph in June 2013 whilst he spent a week with us here in Devon. It seems, that even in such a beautiful, peaceful place, Dave could not find happiness.

A predominantly warm and very sunny month though a little more unsettled in the final week.
