In her fifth Enola Holmes outing, Nancy Springer’s engaging detective finds herself investigating a mystery close to home when her landlady is kidnapped. Enola’s perceptive pursuit of clues leads her down a trail to the past as she learns that Mrs. Tupper crossed paths with Florence Nightingale during the Crimean War and that the disappearance is linked to that encounter. The famous nurse may now be an elderly recluse, but she is still sharp and still commands attention and respect. She is, Enola discovers, a kindred spirit. Not only may she have information that will help her find Mrs. Tupper; she also could be an ally in Enola’s quest for independence as she continues to evade her older brothers, Sherlock and Mycroft, and their intentions to send her to finishing school to be educated as a proper lady. Victorian London again springs to life in the pages of another satisfying entry in this series. (Ages 9–11)
