One secret. Two nations. Three people who uncover the blackmail that pulled America into war—and now the world’s most powerful men want them silenced.

It is late summer in 1929 America. President Herbert Hoover sits in the White House once occupied by his idol Woodrow Wilson—the man who promised in the 1916 election to keep America out of war, then turned on a dime two weeks after his inauguration in 1917 and led it straight into the bloodiest conflict in history.

Pulitzer Prize–winning photojournalist Mattie McGary, accompanying her godfather, Winston Churchill, on his three-month speaking tour of North America, learns of a shocking secret behind Wilson’s abrupt reversal on the war—a secret of blackmail, betrayal, and international espionage. Mattie and Churchill join forces with the man who brought her the secret—the legendary Marine Corps Medal of Honor hero General Smedley Butler—to bring the truth to light.

But powerful men in America and Britain will stop at nothing to keep that truth buried. President Hoover himself and the shadowy head of Britain’s Secret Intelligence Service jointly move to silence them, unleashing both American operatives and British agents to crush the story and protect a legacy built on lies.

From Washington to London, Chicago to Cleveland, Philadelphia to New York and leading to a final deadly confrontation on Long Island’s famed Gold Coast, Mattie, Churchill, and Butler race against time and the world’s most ruthless spies—risking everything to expose the duplicity that changed history and cost eight million lives.

A tale of intrigue, courage, and conspiracy that blurs the line between fact and fiction, The Wilson Duplicity is an authentic, action-packed historical adventure inspired by actual events.
