It all began with Ismo, a Finnish horse doctor who stopped at a garage in mid-Sweden and nearly fell out of his car. He was completely out of control, swinging the wheel of his Merc station wagon into the traffic and the trees, fishing out fruit, pictures of racehorses and tapes of reincarnation philosophy from underneath the driving seat.
As night fell and his driving worsened to a careering lurch, he expounded the wisdom of tuning in to previous lives. His first, he told me, was 36,000 years ago, "and my last one was as a red Indian in Canada".
