Riley Sager released his thriller novel Assassinio sul Phoenix Express through Italian publisher Fanucci Editore under their Timecrime imprint, bringing a high-stakes, closed-room mystery to readers. According to promotional materials and publisher announcements, the novel follows a protagonist named Anna Matheson who boards a non-stop, overnight train to confront six individuals she holds responsible for destroying her family twelve years prior.
Plot Mechanics and the Closed-Room Mystery
Set entirely aboard a high-speed train cutting through a freezing night, the narrative unfolds over a strict thirteen-hour timeline. Under a false identity, Anna orchestrates the journey to trap her targets with the stated intention of seeking justice rather than vengeance. According to Fanucci Editore’s synopsis, the plot thickens before dawn when one of the passengers is murdered. This discovery forces Anna to shift tactics and protect the very people she intended to condemn, as an unknown entity on board actively works to ensure no one leaves the train alive.

Reviewers and literary commentators, including bookstagrammer Federica of 3shadesofbooks, have drawn structural comparisons to classic Agatha Christie mysteries. The novel utilizes a strict chronological pacing—hour by hour—to drive the investigation forward. According to reader reactions shared via literary networks, the restricted setting forces characters into tight proximity, amplifying psychological tension and generating continuous plot twists.
