C. J. Sansom's "Sovereign" is the third mystery in this critically acclaimed series featuring Matthew Shardlake, a thirty-nine year old lawyer, and his assistant, Jack Barak. The author demonstrates his prodigious historical knowledge as he traces Henry VIII's Great Progress to the North in 1541. Along with Catherine Howard, his fifth wife, a large number of soldiers, and members of the nobility, Henry and his retinue made their way from London to York with the goal of bringing the king's discontented northern subjects under control. Archbishop Cranmer sends Matthew Shardlake on the trip to process petitions for the king and to safeguard an important prisoner who is to be interrogated in the Tower of London. Matthew travels with a heavy heart, having recently buried his father, whom he had neglected. With the money that he will earn from this mission, Matthew hopes to pay off his father's remaining debts.
After the Progress finally reaches York, a glazier falls off his ladder and is impaled on fragments of glass. Shardlake quickly realizes that this was no accident. There may be a conspiracy afoot against Henry; papers hidden in the glazier's house would wreak havoc if they were to fall into the wrong hands. Since Matthew caught a glimpse of these papers, he becomes a target and narrowly escapes repeated attempts on his life. Meanwhile, Jack Barak has found love; he is smitten with a pretty young woman, Tamasin Reedbourne, who works in Queen Catherine's household. Matthew and Jack join forces to discover the identity of the killer and to uncover a secret so explosive that it could bring down a mighty monarch.
The strength of "Sovereign" lies in the author's exhaustive attention to historical detail; Sansom immerses the reader in the political, religious, and cultural events of Henry VIII's reign. Tudor England was filled with ruthless individuals who committed immoral acts because of their lust for power, a desire for wealth, and religious fanaticism. Scenes of cold-blooded murder, torture, and suicide reflect the violence and desperation of those volatile times. There is a contemporary flavor to the novel's themes; the more things change, the more they stay the same.
Matthew Shardlake is as admirable and likeable as ever. He has an abnormally curved back which makes him the butt of cruel jokes, but his deformity has not robbed him of his self-respect. His keen intellect and determination propel him to disregard his personal safety in order to bring a murderer to justice. Shardlake and Jack make a solid team: Matthew has experience, a thorough knowledge of the law, and patience; what Barak lacks in seasoning and judgment he makes up for in loyalty, courage, and strength. Jack looks up to Matthew, who has taught the younger man to venerate learning and behave with integrity.
Ironically, the initial strength of the novel ultimately becomes its undoing. The author gets carried away with his verbiage, and the novel soon becomes repetitious and tedious. At nearly six-hundred pages, "Sovereign" would have profited from careful pruning. The large cast of characters is too unwieldy to allow for much shading, and the impact of the mystery is diluted because of the many subplots that compete for the readers' attention. Although "Sovereign" is packed with fascinating information and colorful atmosphere, it would have been far more satisfying had it been more streamlined and better focused.
