What readers say
Readers like this World War I spy-and-medical mystery for its grown-up Becky and Flynn, who have a warm partnership, good banter and a slow-building romance. They praise the vivid field-hospital setting, convincing medical and historical detail, fast pacing, a few surprising twists and Sherlock Holmes cameos. The main criticisms are that the books run short, some feel more like novellas, and endings often stop on a cliffhanger, so reading in order matters. Some say newcomers can follow along but long-time fans of the earlier Sherlock and Lucy books get more out of it.
Best for: Readers who want a fast-paced historical mystery with a slow-burn romance and don't mind short books and cliffhangers.
