Soon another suspect becomes the prime candidate when one of Robicheaux's friends says he saw a man jump off a train and run away. He regrets not reporting it sooner, and it becomes clear that he witnessed the escape of an inmate named Hugo Tillinger who was in prison for murder and arson. He had claimed he was innocent and an organization known for helping prisoners overturn their convictions was looking into his case. The woman who met with Tillinger is Robicheaux's murder victim. It seems like an open-and-shut case, but evidence and motive are never that transparent.
This time the story is not about the mystery itself, but more about the lyrical journey into Robicheaux's past and present that will keep the readers in awe.
