I don't know what makes a legend but the writer of this book, who's prose may have matched the skill of Wodehouse and wrote the funniest book of the 3rd quarter of the 20th century should be a qualifier and he would be if more people had heard of him. Put simply, this book of wind up letters to political movers and shakers of the day, academics, police chiefs and tv celebrities (Mr Root's snarky eye ranged wide) is always funny and more than occasionally hilarious. Most innocently replied, adding to the fun.
It's perhaps too late for legend status as in 2011 the book has the feel of a historical document, with many of the recipients of Mr Root's letters forgotten or unknown to a younger generation. As well as letters to Mrs Thatcher, Angela Rippon and Patrick Moore, recipients included James Anderton (then the notorious Manchester Police Chief) and The Lucy Clayton Model Agency. Where are they now? However, the still living targets won't have forgotten Mr Root, especially the majority who replied to his outrageous assaults.
Willie Donaldson, the creator of Henry Root, wet fish millionaire and man of letters, lived a more than interesting life (a crack addicted prostitute's pimp and would be theatre impresario) and I would recommend Terence Blacker's biography "You Cannot Live As I have lived and Not End Up Like This". Yes, it's a strange corner of literature, but always great fun.
