The streets of London can be dangerous—but so can this secret society of crime-solvers . . .

Monica is barely a month into her role as leader of The Twelve—a clandestine group of retired experts tasked with eliminating London's most dangerous criminals—when a new case presents a major challenge. Ex-plumber David Latham brings them a personal mission: hunting down a suspect who walked free after the racially-motivated murder of his best friend's son.

But as Monica and her team dig deeper, they uncover a web of corruption that reaches back decades. Old photos, hidden bribes, and buried secrets reveal the true killers—and a sinister legacy of violence.

As alliances are tested and enemies emerge from the shadows, Monica must lead The Twelve on a lethal pursuit to plot their own form of justice in this exciting new novel by the author of Lunch with the Deadly Dozen.
