Someone was sending the comfortable citizens of Edinburgh poison-pen letters, but the recipients thought it politic to say nothing about them. Dilly Gosset, the French-born wife of a judge, had received one of the letters & blurted out the details of her husband's not so blameless life to anyone who would listen. Spurred on by the appparently accidental, death of Lady Gosset, Diana Drummond began to investigate. Her discoveries led her to wonder if Lady Gosset's death had indeed been an accident.
