On a Thursday evening in September 1922, a phone call placed to Reverend Edward Hall—a respected Episcopal minister—would lead to one of the most sensational "Jazz Age" scandals in American history.

Two days later, the Reverend's body was found alongside his lover, choir singer Eleanor Mills, posed beneath a crab apple tree. Their passionate love letters were torn and scattered around them like confetti, a clear message from a killer driven by jealousy.

We are diving into one of the great unsolved mysteries of the Jazz Age, a case so baffling it feels like the plot of a spy novel. This is the story of Captain Alfred Lowenstein, the third-richest man in the world in 1928, a man who owned estates across Europe and brokered deals with kings.
