Princess Diana's Revenge is a novel written by the English writer Michael de Larrabeiti and published in 2006 by Tallis House. In the context of de Larrabeiti's other work it is perhaps closest in tone to his thrillers The Bunce and The Hollywood Takes, dealing with conspiracy theories and partly featuring the documentary film business in which de Larrabeiti's earlier novels were set.
Despite de Larrabeiti being an established author of thirty years standing, Princess Diana's Revenge was turned down by his literary agents, Curtis Brown. The novel was then turned down by over thirty publishers in the United Kingdom. In response to this de Larrabeiti decided to self-publish under his own imprint, "Tallis House". He is one of the first established authors to self-publish, along with the Canadian writer Jim Munroe.
Princess Diana's Revenge tells the story of Joe Rapps, a director and cameraman who slips into the surreal world of Milton Magna, an Oxfordshire village which is based on the real village of Great Milton where de Larrabeiti has lived for over thirty years. Rapps is drawn into various conspiracies revolving around the Friends of Diana, a cult which has grown up around the memory of Princess Diana and is determined to avenge her death.
Although Princess Diana's Revenge is not as explicitly anti-authoritarian as de Larrabeiti's most famous work, The Borrible Trilogy, its satire of members of the Royal Family ensure that the book is run-through with the anti-authoritarianism that is present in all of de Larrabeiti's work.
The novel's central character is Joe Rapps, a director-cameraman. At the start of the novel Rapps is released from Wandsworth prison, where he was imprisoned for accidentally killing two children while driving drunk.
