One angle on this story comes into A.L. Rowse's brilliant, family portrait of the Churchills, for the Duke of Marlborough and his ebullient wife, Sarah, were figures on the scene at the time. Another angle- concentrating on the French debacle, is treated is biographical fiction, by Thomas Costain, in The Moneyman, his name for John Law, who sparked the whole period of speculation and financial intrigue.
