An investigation examines the case of a violent neighbour who terrorised a couple in rural Wales, exploring the background and circumstances that shaped his behaviour before his death. The case drew attention partly because of a striking family connection: the man was reportedly the son of one of the SAS soldiers who took part in the storming of the Iranian Embassy in London in 1980, one of the regiment's most celebrated operations.
