"The novel is based on the well-known, unsolved murder by poisoning of Charles Bravo in Victorian-era London. The victim, re-christened Charles Cranbrook in the novel, died in his bed from poisoning a mere four months after marrying the beautiful and exceptionally wealthy Cecilia Henderson. During the course of the coroner’s inquest into the death it emerged that Cecilia had been involved in a scandalous affair with the much older, famous physician Dr. James Gully, whose patients numbered William Gladstone, Lord Tennyson and Charles Darwin. In Fell the Angels, Cranbrook’s mysterious murder is investigated by the brilliant crime detective Duncan Cameron"--Author's website.
