The Smiler With the Knife

Detective Nigel Strangeways, and his explorer wife Georgina, have taken a cottage in the countryside. They are slowly beginning to adjust to a more relaxed way of life when Georgina finds a mysterious locket in their garden and unwittingly sets the couple on a collision course with a power-hungry movement aimed at overthrowing the government. It will take all of Nigel's brilliance and Georgina's bravery if they are to infiltrate the order and unmask the conspirators.
