In the city of Lichfield for crowds are drawn irresistibly by Jonjo, the busker, and his strange, haunting, hypnotic music, a weird melody that lingers with the listeners long afterwards, a nuisance by day but terrifying in the nocturnal hours, calling them, commanding them. Jonjo's warning of impending doom is coming true as tiny corn people are glimpsed flitting through the autumnal mists. Then the crop circles appear as if to herald Armageddon. And throughout, Jonjo's melody is a symphony of madness and death. What is happening? Why? Only the Busker knows the answers.
