Geoff Nicholson is a highly prolific writer, yet this is my first exposure to his work. As such, it was something of a revelation, although I don't believe that's quite the proper term. A quick glance over Nicholson's body of work reveals something of a preoccupation with sex, an impression well-backed-up by this book.
The Food Chain is primarily a book about a well-aged old boys' hangout known as "The Everlasting Club". Britain's past is full of such clubs, and in fact perhaps the best known and most infamous, the Hellfire Club, is mentioned in this book as a contemporary of this fictional organization, each with their own array of dark secrets.
