A Harlem speakeasy, far from Wall Street. A melancholy song called “Lush Life.” The leader of a growing American Nazi movement. In the opening episode of The Graham Plan, my serialized historical thriller set in 1936 New York, Ben Graham’s evening takes an unexpected turn when a friend presents him with a choice that appears ordinary— but could undermine his newfound sense of security and change the course of his life.

Dear Readers, I’m taking a break from writing biographical pieces about my grandfather, Benjamin Graham, to begin The Graham Plan, a serialized historical thriller set in 1936 New York. A brilliant lone-wolf investor named Ben Graham—inspired by the real man—must unite an unlikely band of allies to stop dangerous pro-Hitler fanatics. I hope you’ll join me for the Author’s Note and, soon after, the first episode.
