Behind Palace Doors by Nigel Dempster
Tells of the marriage of Prince Charles and Princess Diana and other events which led the Queen to observe that the royal family had undergone an "annus horribilis". Recent royal events hold a terrible fascination. Through the monarchial merry-go-round of loves and liaisons, marriage and separations, divorces and remarriages, this book reveals the bewildering tangle of alliances, hostilities and traumas that are part of the Windsor knot that Princess Diana claimed choked the life out of her marraige.
