Tintin and the Picaros

Many years ago when my love of Tintin books began, I always found this book made me a little sad. I had always figured this emotional reaction was due to the fact that Tintin and the Picaros is the last of the wonderful series. However, after reading the excellent book Tintin and the World of Herge by Benoit Peeters, I understood that the great Herge himself was reaching the end of his rope.
