The First Lord Nanther, expert in blood diseases, particularly the royal disease of Haemophilia, and favoured physician to Queen Victoria, clearly hoped to be the subject of an admiring posthumous biography. But when his great-grandson, Martin Nanther begins to research his life for a biography, the Martin comes to suspect that his great-grandfather’s old records conceal more than they reveal.

Henry had been obsessed with blood, to him, blood was a thing of beauty and he could not fathom how anyone could flinch or faint at the sight of it. As Martin’s research deepens, he begins to wonder whether the mysterious deaths of a number of friends and relatives of his great-grandfather really were mere coincidence or did Henry’s fascination with blood have a much darker side?
