In line with Tintin in the Congo and this somewhat dismissive aside for indigenous (Hergé replaced by African Indian) this 3 rd adventure is really childish !!! One must read it when you are tintin but it is hardly exciting and really dates from another era! just back of Congo, our hero and his dog are forwarded to Chicago where he is responsible to stop the notorious Al Capone and his gang. Some funny scenes however but this story is not very exciting.
