October, 1812: Britain and France are still at war. France is engaged on two battle fronts - Spain and Russia - and her civilians are growing weary of the fight. Rebellion is brewing. Since Napoleon Bonaparte appointed himself as First Consul, there have been several attempts to either kill or overthrow him. All have failed, so far.… Meanwhile in London, Bow Street Runner Matthew Hawkwood has been seconded to the foreign arm of the Secret Service. There, he meets the urbane Henry Brooke, who tells him he’s to join a colleague in Paris on a special mission.
1812: Matthew Hawkwood, soldier turned spy, is stranded behind enemy lines, in America, a country at war with Britain. Heading for the safety of the Canadian border, Hawkwood's route takes him to Albany where the chance sighting of a former comrade-in-arms - Major Douglas Lawrence - within a consignment of British prisoners puts paid to his plans. For as the two men make their escape they uncover an American plot to invade Canada. If it is successful, the entire continent will be lost. The British authorities must be warned.
