'They have sent me here because of what happened on the pylon' When Clodagh Brown writes these words at the age of 19, she believes that she is leaving behind the traumatic events of her youth. But Clodagh soon learns that you can never entirely escape your past. In the aftermath of the incident on the pylon – a gargantuan electrified grasshopper – Clodagh goes off to university, moves into a basement flat arranged by her unsympathetic family and finds freedom trekking across London's rooftops with a gang of neighbourhood misfits. As she begins a thrilling relationship with a fellow climber, however, both Clodagh and the listener are haunted by the memory of the pylon and of the terrible thing that happened there – and by the eerie sense that another tragedy is just a footfall away.
