Full Dark House
By Christopher Fowler
"It was an investigation that began with the grisly murder of a pretty young dancer. In a city shaken by war, a faceless killer stalked London’s theater row, creating his own sinister drama. And it would take Bryant’s unorthodox techniques and May’s dogged police work to catch a fiend whose ability to escape detection seemed almost supernatural—a murderer who decades later may have returned to kill one of them--and won’t stop until he kills the other."
