Mistaken identity makes the murder of an author’s doppelganger at Castleton Manor seem all the more malicious. Upscale literary retreat Castleton Manor prepares to host a retirement celebration for Red Maxton, the author of the best-selling Trey Connor spy series. Librarian Faith Newberry plans for the arrival of Red's die-hard fans, who will converge on the manor to celebrate Red's career. Before the event begins, a dead man is discovered in the hedge maze. He looks just like Red, and he was carrying the three of diamonds, Red's fictional spy’s calling card. With the guest of honor dead, the event is canceled … then Red shows up, alive and well. Red's sudden appearance sends shock waves throughout the manor. While the event continues to be disrupted by mysterious incidents, Faith endeavors to identify the man in the maze and unmask his murderer. Will Faith—along with her devoted cat, Watson—play her cards right? Or is there another ace up the villain’s sleeve? This clever whodunit from Annie’s Secrets of the Castleton Manor Library series is a must-read for fans of cozy mysteries, reading, pets, and female friendships.
