When I started the Security Hazard blog just over four years ago I had recently moved to the other side of the world, was living with my incredibly generous and incredibly new in-laws, and (due to the joys of the US immigration system) faced many months of unemployment. It was a time that was scary and exciting in equal measure. With time on my hands, I turned my attention to something which had been an absolute constant in my life since Day 1 – the work of Gerry and Sylvia Anderson.
