John Law was by any standards a quite remarkable man. At the apogee of his power in 1720, he was the richest private citizen in Europe and controller-general of finance in France, responsible not merely for the country’s income and expenditure but for its commerce, navigation, agriculture and industry.
He created and presided over one of the earliest and greatest of all stock market boom-and-busts, that of the ‘Mississippi Company’, and inspired another, the South Sea Bubble. And he pioneered ideas about banking, monetary policy and financial markets that were revolutionary in his own time, and retain their importance three centuries later.
Yet Law was not French, not a noble, not an intellectual. On the contrary: he was a Scot, the largely self-educated son of an Edinburgh goldsmith, and a brilliant gambler. Oh yes, and a convicted murderer, who had escaped from jail days before his execution, fled Britain and gone on the run across Europe with his common-
law wife.
The story is no less remarkable than the man himself. But both have almost been lost to view. The evidence is scant and scattered, Law himself something of an enigma, his era caught in a turn-of-the-18th-century limbo between the more familiar territories of the so-called ‘Age of Revolutions’, Glorious, American and French. And he is no one’s hero.
Until now, that is. For into this gap steps the polymathic figure of James Buchan: writer of fiction, history and reportage, and author among much else of an excellent life of Adam Smith.
Buchan tells the story and portrays the man with enormous sweep and brio. He has clearly done a vast amount of research among the primary sources, yet somehow manages to combine the historian’s sense of the wider picture with the epigrammatic wit of the novelist, and the antiquarian’s delight in curios.
