Query: A good book but a despicable author

I read this book some time ago and I did enjoy it, but upon learning now that Richard Took used his time in Russia while researching this book to abuse young children, including extremely young children/toddlers, I don't feel we should promote or buy a book that lines his pockets. Amazon should ashamed that they are still selling this book.He has been jailed in the UK (search on the Roger Took article in The Spectator newspaper), and as the crimes were so severe he may never get parole, but reading the passages in the book where he lived amongst the people to get his story while abusing their children, sickens me.Roger Took's abuse went much wider than just these Russian children, and involved serious abuse of children worldwide including his grandchildren, step grandchildren and a disabled child.Before you purchase this book, I strongly recommend you google him for the Spectator and BBC articles, and then decide if you really want to buy it.
