The William Monk mystery series follows William Monk, a police detective in Victorian England, who faces the unique challenge of solving crimes while suffering from amnesia. This condition complicates his investigations and personal life as he pieces together memories of his past and seeks to uncover his forgotten identity.

Darker and more psychological than Anne Perry’s popular Charlotte and Thomas Pitt series, the Monk series delves into the grimmer aspects of Victorian society, including social injustices, political corruption, and moral dilemmas. Readers are captivated by Monk’s journey of self-discovery and the intricate plot twists and character development. Many mystery fans name William Monk as their favourite Anne Perry series.

As Monk’s investigation into his past unfolds throughout the series, reading the books in order is more essential to fully enjoy the ongoing narrative compared to Perry’s other series.
