A compelling story of power, passion and intrigue based on real events, The Prime Minister's Affair is a terrific read - Nick Robinson, Presenter, BBC Today programme

London 1929. Very much not a land fit for heroes. Frenchie knows his occasional work for MI5 serves only the ruling classes. But he needs to feed his children. Scruples died in the trenches.

When Ramsay MacDonald, Britain's first Labour Prime Minister, is blackmailed by a former lover, Frenchie must go to Paris to buy her silence.

It is clear there are many people who would see MacDonald fall - the Conservatives, their friends in the press, even some of his own colleagues. But his own secret service? When Frenchie hears the other side of the story, everything changes.

The Prime Minister's Affair is another brilliant historical thriller from the author of Witchfinder, based on a real blackmail plot, hidden in the shadows.
