In 1543, while Tudor England is abuzz with King Henry VIII's wooing of Lady Catherine Parr, Matthew Shardlake is working to defend a teenage boy, a religious fanatic being held in the infamous Bedlam hospital for the insane. Then, when an old friend is murdered, Shardlake's search for the killer leads him back not only to Bedlam but also to Catherine Parr-and the dark prophecies of the Book of Revelation.
