Julius Caesar turns to psychological warfare... Tortuous Convolvulus the Roman agent is guaranteed to sow jealousy and discord anywhere. Can he make the Gauls suspect each other of treachery? Has Asterix really sold Rome the secret of the magic potion? And can Asterix, Obelix and Getafix outwit the weedy but wily Convolvulus and get the village back to normal?
Out at sea fishing, Asterix and Obelix are blown off course in a storm. Luckily they land on the shores of a Roman colony - or is it? Teepees, totems, gobbling birds: it's not what they're used to. And what are the Viking explorers in their longship doing? But perhaps 50 BC is a little too early for a voyage of discovery to this strange New World...
One dark and stormy night, a sinister figure arrives in the little Gaulish village. Prolix, who claims to be a soothsayer, prophesies that when the storm is over the weather will improve. And it does! Now the credulous villagers believe every word he says, but Asterix has his suspicions of the smooth-talking Prolix. Who is really right about the soothsayer?
Julius Caesar sends Caius Preposterus, a bright young graduate of the Latin School of Economics, to corrupt the indomitable Gauls by introducing them to big business. Obelix's menhir trade is soon thriving, backed by a heavy advertising campaign - but does wealth bring happiness? And what will happen when the bottom falls out of the menhir market?
