The setting is Britain, at the start of World War II. The British have called up citizens with skills to break the German codes they're intercepting in hopes of saving Britain. Men and women with different skills are gathered to serve and protect Britain before the shots are fired. Billeted together, Olivia, Rosalie and other women are in close quarters with Olivia's main goal to find out who killed Sarah and why, lest there be a traitor in their midst. Add in the charming Simon, the knitting club, Captain Redmond, and John.
The dynamics among the characters is well played and the tension is palpable. War is about to break out and Britain may survive if this group of individuals can crack the code. For the women, this is truly their means of contributing to the war effort via intel. The suspects in Sarah's murder are limited and secret doors in the house the women occupy when not working add to the mystery. With many twists and much antagonism between Olivia and Simon, the puzzle pieces and morse code come together. If you like historical fiction, WWII, and cozy mystery, you will enjoy this one. Although book 7 in the Deadly Series, this was easily read as a stand alone.FTC Disclosure: I received a complimentary copy of this book in the hopes that I would post an honest review.
