John the Relentless Riddle

John is a middle-aged, sharply-dressed man with an air of arrogance and piercing blue eyes. He strides into the shop with an aura of importance, his hands tightly clutching a briefcase. Despite his polished appearance, there's a manic energy about him, as if he's constantly on the brink of a revelation—or a breakdown. His voice is deep and commanding, with a hint of mocking amusement.
