Asterix : Asterix and the Cauldron 13 by Rene Goscinny,Albert Uderzo

Financial skulduggery in ancient Gaul! When local Chielf Whosemoralsarelastix wants a cauldron full of money kept out of Roman hands, the cash disappears while Asterix is guarding it. He and Obelix must earn enough to repay it through fairground gladiatorial contests, trendy theatrical performances, even bank robbery - they'll try anything. But whose morals are really eleastic? And how do the pirates, just for once, get an unexpected bonus.
