Assistant DA Alexandra Cooper returns in the new breakneck thriller by the New York Times bestselling author of Death Angel who once again captures the essence of New York City—its glamour, its history, its possibilities, and its endless capacity for darkness. Grand Central Station is hiding more than just an underground train system. When the body of a young woman is found in the tower suite of the Waldorf Astoria, Assistant DA Alex Cooper and Detective Mike Chapman find themselves hunting for a killer whose only signature is a carefully drawn symbol carved into his victims’ bodies, a symbol that bears a striking resemblance to train tracks.After a second body is discovered in a terminal alleyway, attention shifts to the iconic transportation hub and the potential for a bigger attack. With the President of the United States set to arrive for a United Nations meeting, Alex and Mike must contend with Grand Central’s expansive underground tunnels and century-old dark secrets—as well as their own changing relationship—to find a killer who’s cutting a deadly path straight to the heart of the city.
