Using the multiple-viewpoint technique that worked well in The Boleyn Inheritance (2006), Gregory fictionalizes a little-explored episode in the life of Mary, Queen of Scots. In 1568, after fleeing rebellious Scottish lords, Mary is placed into the custody of George Talbot, Earl of Shrewsbury, and his wife, Bess of Hardwick. This turns their Derbyshire estate into a hotbed of intrigue and possible treason. George, normally loyal to a fault, falls in love with Mary; Bess secretly reports to William Cecil, Queen Elizabeth’s spymaster, while fretting about her foolish husband and the continual draining of their funds; Mary plays them against one another while plotting to escape, with Cecil noting her every move. Gregory skillfully evokes the suspenseful atmosphere—it was never certain that the 1569 Rising of the North in favor of Catholic Mary would fail—but the protagonists’ inner thoughts, as presented in short alternating chapters, are unnecessarily repetitive. Although this isn’t her best work, Gregory’s writing is sharpest toward the end, as the unavoidable consequences of Mary’s long imprisonment are finally felt by all.
