The blood doctor - Barbara Vine

Sometimes it's best to leave the past alone. For when biographer Martin Nanther looks into the life of his famous great-grandfather Henry, Queen Victoria's favorite physician, he discovers some rather unsettling coincidences, like the fact that the doctor married the sister of his recently murdered fiance. The more Martin researches his distant relative, the more fascinated-and horrified-he becomes. Why did people have a habit of dying around his great grandfather? And what did his late daughter mean when she wrote that he's done "monstrous, quite appalling things"?

Barbara Vine (a.k.a. Ruth Rendell) deftly weaves this story of an eminent Victorian with a modern yarn about the embattled biographer, who is watching the House of Lords prepare to annul membership for hereditary peers and thus strip him of his position.
Themes of fate and family snake throughout this teasing psychological suspense, a typically chilling tale from a master of the genre.
