On a visit to Bath, Major Sir Robert Kurland and Lady Lucy Kurland discover that the English spa town is not beneficial to everyone's health . . .
After Sir Robert's injury from the battle of Waterloo begins troubling him again, his wife Lucy insists they relocate from the village of Kurland St. Mary to Bath, along with her sister Anna, so that Robert can take the waters and recover.
At the Roman baths, Robert befriends an elderly and pugnacious businessman, Sir William Benson, ennobled by the Crown for his service to industry. Their acquaintance is short-lived, however, when the man is found drowned in the baths. Robert vows to find his killer, with Lucy's aid.
The members of Sir William's family seem the most obvious suspects to benefit from the wealthy man's death, but his will has gone missing. To deduce who sent Sir William to a watery grave, Robert and Lucy must investigate with the utmost discretion—before they too find themselves in over their heads . . .
Set in 1822, Lloyd's well-crafted sixth Kurland St. Mary mystery (after 2017's Death Comes to the School) takes Sir Robert Kurland and his wife, Lucy, to Bath, where he can take the waters for an old war injury suffered at Waterloo. There they grow friendly with Sir William Benson, an elderly Yorkshireman whose businesses have earned him wealth and a peerage. Benson controls his squabbling family, whose failings he publicly derides, with threats of disinheritance; when he's found stabbed in the Roman baths, all have motives. His beautiful second wife is greedy and deceptive, his three sons all have money troubles, and his two stepsons make no secret of their contempt for the victim. As the Kurlands investigate Benson's murder, they contend with his missing will, a second death, and coded letters that may help illuminate the family's many secrets. Lucy's desire to bear children despite a string of miscarriages adds appealing personal drama. The couple's complementary investigative skills shine in a plot that balances colorful characters and lively action.
