Charlotte Warburton first encounters Jack Finney at his Leonardo da Vinci lecture at the Art Institute of Chicago. This is where Jack makes a wild claim—that he is a time traveler and the long-time apprentice of Leonardo da Vinci, better known as Andrea Salaì. After claims of Jack making drunken bets with da Vinci and knowing secrets about the Mona Lisa, Charlotte is intrigued. She decides that Jack will be the subject of her next podcast series. As she reveals the oddities of Jack’s lecture, she warns that this story will turn into far more than a tale of time travel.
