First published in 1966 and 1967, Tintin, Snowy, Captain Haddock and Professor Calculus head to Australia on the private jet of Laszlo Carreidas. This story has plenty of action...a hijacking, a truth serum, treachery, explosions, fights...even outer space aliens. The adventure leads to a mysterious Pacific island where their old enemy Rastapopoulos awaits. Using a truth drug on Carreidas, he hopes to steal the number of the millionaire's secret Swiss bank account, but, thanks to Tintin, his plans go strangely awry.
