A wall can be judged more dangerous than a sword. England, 1486. The wars are over, but the Crown is not at ease. Henry VII rules a kingdom exhausted by private armies and fortified houses-men and stone that once defied kings. Now, loyalty is no longer proved in battle, but measured quietly, recorded in ink, and enforced by law. When Sir Edmund Harrington authorizes repairs to his ancestral castle in the north, he believes he is acting prudently, even innocently. The walls have stood for generations. The work is necessary. Permission was once granted-under another king. But Henry Tudor's England is not governed by memory. Without accusation or spectacle, royal commissioners arrive. Measurements are taken. Questions are noted. What begins as inspection becomes attention, and attention hardens into suspicion. Harrington's eldest son is summoned to Westminster-not as a prisoner, but as assurance, even as his youngest is assigned to local service in the Crown's interest. Attainder is a tense, meticulously researched historical novel about the rise of administrative power under Henry VII-where obedience is enforced without bloodshed, and the greatest danger lies not in rebellion, but in being noticed.
