"A novel" - cover.

When the body of a young woman is found in the tower suite of the Waldorf Astoria, Assistant DA Alex Cooper and Detectives Mike Chapman and Mercer Wallace find themselves hunting for a killer whose only signature is a symbol that bears a striking resemblance to train tracks carved into his victims' bodies. When a second body bearing the same bloody symbol is discovered right next to Grand Central Terminal, all attention shifts to the iconic transportation hub. With the president of the United States set to arrive for a United Nations meeting at the weeks end, Alex and Mike must contend with Grand Centrals expansive underground tunnels and century-old secrets.
