Are the nude spies lolling in the ancient Roman communal baths of Elizabethan England plotting the return of Mary Queen of Scots? She is said to be clamoring to return to these healing waters. Once again Susanna, Lady Appleton, encounters murder and treason, and only she can unravel the crimes in the intriguing year of 1575. Rosamund, Susanna's twelve-year-old foster daughter, is certain her French tutor has been murdered. Rosamund and her friends are quite modern: they cut school, rebel against authority, and giggle over secrets. But can teenage mischief be construed as spying and treason? These are most significant matters to the Elizabethans, as the wrong religion, the wrong marriage, the wrong friends...may all be seditious.
