Among Anne Perry's other novels featuring investigator William Monk are The Silent Cry, Cain His Brother, Defend and Betray, Weighed in the Balance, A Breach of Promise, and, most recently, Slaves of Obsession. She also writes the popular novels featuring Thomas and Charlotte Pitt, including Bedford Square, Pentecost Alley, Traitors Gate, The Hyde Park Headsman, Highgate Rise, and Ashworth Hall.
