It was a short review, but it said that it was probably the best authenticated case of reincarnation on record. So I hastened to buy the book, which was published by Spearman—a firm that seemed to have succeeded Rider as England's chief 'occult' publishers. The book arrived in mid-September. It had a sub-title: 'The record of a past life in 13th century France'. I settled down to read it; from the blurb, it sounded fascinating. My first impression was of disappointment. It began by stating that one of the writer's patients—he was a doctor—had written down all kinds of details about the Cathars, a heretical sect of the twelfth and thirteenth centuries, and that at the time she wrote, most of these details were unknown to scholars. Since that time—twenty-six years ago—many of these details have been verified, said Dr Guirdham. He certainly had my attention. In fact, it seemed fairly clear to me that he had the material of a best-seller.
