It is 9.07am on a grey July morning in London; a bewildered young man wanders the streets of the capital. Something has gone wrong. Again and again, he calls his friends for advice but they have already left without him. Around him, the city is descending into chaos. Ambulances are screaming down streets, train stations are being closed, and thousands of commuters are trapped. Scotland Yard and Downing Street are on alert as report after report of explosions fills all of the police radio channels.

But still this eighteen-year old soldier, this perfect killing machine, presses on with his mission. Checking and re-checking the electrical connections of his device, Leeds-born Hasib Hussain finally presses the detonator to reach paradise, and murders thirteen of his fellow passengers on the number 30 bus in Tavistock Square.

What has this act of terrorism got to do with religious broadcasting, traditionally seen as the preserve of stories about leaky church roofs, controversial gay Church of England vicars and the ‘crisis of faith’ in the inner city?
