When the vision came, he was in the bathtub. So begins the madness of Louis Daguerre. In 1847, after a decade of using poisonous mercury vapors to cure his daguerreotype images, his mind is plagued by delusions. Believing that the world will end within one year, Daguerre creates his “Doomsday List”—ten items he must photograph before the final day. The list includes a portrait of Isobel Le Fournier, a woman he has always loved but not spoken to in half a century.

In this luminous debut novel, Dominic Smith reinvents the life of one of photography's founding fathers. Louis Daguerre’s story is set against the backdrop of a Paris prone to bohemian excess and social unrest. Poets and dandies debate art and style in the cafés while students and rebels fill the garrets with revolutionary talk and gun smoke. It is here, amid this strange and beguiling setting, that Louis Daguerre sets off to capture his doomsday subjects.
