In "Diamantbägaren från Indien," the Phantom is drawn into a jungle mystery when a feverish hunter claims to have seen him perform a ritual with a cup carved from solid diamond. The hunt for the legendary artifact leads to treachery among a desperate expedition, with betrayal unfolding like a trap set in the wild. As the Phantom tracks the thief across jungles and skies, he must untangle greed from loyalty—before the cup's fate is sealed.
