The author Charles Palliser named the fifth and final volume of his epic The Quincunx: The Maliphants.

I asked him why he chose ‘our’ name, and he told me ‘No special reason. I liked the name and thought it fitted’.
He can’t remember where he saw the name though ….

Loads of references to the book and its 4 predecessors and opportunities to purchase it if you Google it 🙂
