In a masterly new thriller by the New York Times bestselling author of the Rizzoli & Isles series, a beautiful violinist is haunted by a very old piece of music she finds in a strange antique shop in Rome.

The first time Julia Ansdell picks up “The Incendio Waltz,” she knows it’s a strikingly unusual composition. But while playing the piece, Julia blacks out and awakens to find her young daughter implicated in acts of surprising violence. And when she travels to Venice to find the previous owner of the music, she uncovers a dark secret that involves dangerously powerful people—a family who would stop at nothing to keep Julia from bringing the truth to light.
