Barbara Vine's new novel is about blood - blood in its metaphysical sense as the conductor of an inherited title and blood in its physical sense as the transmitter of disease.

The current Lord Nanther, experiencing the reform of the House of Lords, embarks on a biography of his great-grandfather, the first Lord Nanther, favoured physician to Queen Victoria, expert on blood diseases and particularly the royal disease of haemophilia. What he uncovers begins to horrify him as he realizes that Nanther died a guilty man - carrying a horrific secret to the grave.

The Blood Doctor weaves effortlessly between past and present, public life and private life. The result is a superbly satisfying novel about ambition, obsession and bad blood.
