This is the adaptation of the eponymous novel by Erik Larson published in 2003, which takes place in Chicago in 1893 during the World's Fair, while the paths of Daniel H. Burnham, a brilliant architect seeking to leave a trace in history, and a serial killer cross paths.
False doctor, the serial killer wants to open a hotel during the event with the aim of making it a "murder palace" in which he will torture and murder dozens, even hundreds of women. Sam Shaw (Castle Rock) will be the screenwriter and showrunner of the future series. A priori, Leonardo DiCaprio should not play in the series. No info yet for France, we'll keep you posted.
