A bomb rips through present-day London, tragically ending the crime-fighting partnership of Arthur Bryant and John May begun more than a half-century ago during another infamous bombing: the Blitz of World War II. Desperately searching for clues to the saboteur's identity, May finds the notes his old friend kept of their very first case and a past that may have returned...with murderous vengeance. 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.
