He's done jailbird, and he's done author. Now, it appears that the ever-sinister David Irving is attempting life as a tour guide. The discredited historian, who once denied that Auschwitz existed to murder Jews, is offering punters the chance to take a guided tour of "Hitler's Headquarters and other historical sites". For $2,900 (£1,900), says a brochure for the trip, tourists will be given a tour of wartime headquarters, including the notorious "Wolf's Lair" in what is now Poland, and a visit to Treblinka death camp. Whether anyone will take the tour remains to be seen; Irving declined to tell Pandora of any interest. Even more curious is Irving's decision to use a quote from Mr Justice Gray's ruling at the Irving vs Lipstadt trial in order to sell the idea. Mr Justice Gray ruled that Irving had "manipulated historical evidence"; Irving, though, cites a rather more positive version of the ruling, quoting Mr Justice Gray on his website as claiming that his "knowledge of World War Two is unparalleled".
