In A Friend to Alexander, the story unfolds around Harry, an ordinary man whose life takes a dark turn when he begins experiencing vivid and unsettling dreams about Aaron Burr, the infamous historical figure known for his duel with Alexander Hamilton. Initially, Harry's dreams seem harmless, merely a curious quirk of his subconscious. He shares these dreams with his wife, Bess, who finds them amusing at first, but as the nights progress, the dreams become increasingly intense and disturbing. Harry describes encounters with Burr in various familiar settings, such as Washington Square and Broadway, where Burr appears to him with a sinister charm, recounting tales of his past and engaging in conversations that blur the lines between history and Harry's present reality.
