Includes an excerpt from Kill the angel by the author.

When a woman is beheaded in a park outside Rome and her six-year-old son goes missing, the police unit assigned to the case arrests the woman's husband and awaits his confession. But the city's Chief of Major Crimes has his doubts and assigns two of Italy's top analytical minds to the case: Deputy Captain Colomba Caselli, a fierce, warrior-like detective still reeling from a horrific mass killing she survived, and Dante Torre, a man who spent his childhood trapped inside a concrete silo. Fed through the gloved hand of a masked kidnapper who called himself "the Father," Dante emerged from his ordeal with crippling claustrophobia but, also, with an unquenchable thirst for knowledge.
