Elmo McElroy is a streetwise American master chemist who heads to England to sell his special new formula - a powerful, blue concoction guaranteed to take you to the 51st state. McElroy s new product delivers a feeling 51 times more powerful than any thrill, any pleasure, any high in history. But his plans for a quick, profitable score go comically awry when he gets stuck in Liverpool with an unlikely escort and his ex-girlfriend and becomes entangled in a bizarre web of double-dealing and double-crosses.

This is the extraordinary story of a beautiful mathematical formula that changed the world, the financial markets, and indeed capitalism itself. It could do the unthinkable - it took the risk out of playing the money-markets. To its inventors it brought the Nobel Prize for economics. To those who used it, it brought great wealth. But this glittering tale would end in tragedy.
