Serial Killer Sudoku: A Katie McDonald Mystery
Mathematician Katie McDonald is the owner and curator of the Avondale Puzzle Museum in Granville, New Hampshire. When the new owner of the local newspaper begins to cause a panic by suggesting that a Boston serial killer is headed to Granville, Katie and police chief Brandon Mitchell try to quash the rumors. However, when an unpopular resident is found murdered, and Katie begins to receive messages from the killer in the form of Sudoku puzzles, she becomes immersed in the investigation. Her involvement deepens when Brandon is injured and can no longer lead the hunt for the killer. Assisted by Brandon’s 14-year-old ward, Harry, Katie solves the crime, with Brandon’s help in the final hour. In this third in a series, Katie begins to acknowledge her growing romantic feelings for Brandon, and the town’s residents begin to accept this outsider as a member of their community. Sudoku fans and readers of Parnell Hall’s Puzzle Lady mysteries will enjoy this series. --Sue O'Brien
