In The Price of Murder, Sir John and Jeremy are drawn deep into the notorious Seven Dials section of London, where they must contend with the most sordid inclinations of both the working class and the aristocracy. When the body of a young girl is pulled from the Thames, Sir John and Jeremy begin to investigate; but the girl's mother is nowhere to be found, until Jeremy's search for clues leads him to the racetrack. There, he discovers just how dangerous the high-stakes battle is that he has gotten himself into-and, when an acquaintance of his own suddenly disappears, just how terribly steep the odds.
