How would you feel if you found a set of Rosary beads in a quiet corner of a Free Presbyterian church? Or some cricket pads in a GAA changing room? Then imagine the shock that came over the Margin's two agents on a recent visit to the FINEX trading floor in Dublin's IFSC.

Here was capitalism in the raw; well-fed young men and women in a pit, bellowing million-dollar orders at one another. Urged on by the supervisors thus: "C'mon, bid, offer it's not your money!"

But stuck underneath one of the desks overlooking the pit was a tiny corner of red paper. Our agents moved in to investigate, tugged at it surreptitiously. It was a thin book, well-thumbed, used regularly. Its title? The Communist Manifesto by Karl Marx and Friedrich Engels.
