Sea Change by Robert Goddard

Description

It is January 1721. London is reeling from the effects of the greatest financial scandal of the age, the collapse of the South Sea Bubble. William Spandrel, a penniless mapmaker, is offered a discharge of his debts by his principal creditor, Sir Theodore Janssen, a director of the South Sea Company, on one condition: he must secretly convey an important package to a friend of Janssen’s, Ysbrand de Vries, in Amsterdam.
Afterwards, Spandrel realizes that he has become a pawn in several people’s games. British Government agents are on his trail, believing that the mysterious package contained secret details of the great South Sea scandal – secrets so explosive that their publication could spark a revolution in England.
Spandrel’s only chance of survival is to recover the package and place its contents in the right hands.
