“An intelligent and engrossing historical novel with an wonderfully independent heroine (of the right social class!) and her enterprising maid. But it is by no means a cozy story, delving into the grim realities of war.”
—Rhys Bowen, New York Times bestselling author of the Molly Murphy and Royal Spyness mysteries

—Victoria Thompson, bestselling author of Murder in Morningside Heights

—Ashley Weaver, author of the Amory Ames mysteries
