1919 – England
The storm is coming.
When the Great War ends, former cryptographer Lady Jill Morgan has only two things remaining: to host a house party for her brother and to decide her future. That changes when she receives a warning from her one-time employer that her guests may not be as they seem.
Captain Richard Darnaway comes to Huntingtower with his own plans – plans that don’t involve tracking traitors like he did during the war. But he finds he needs all his old skills when a perhaps-not-so-retired fellow agent is murdered.
Now Richard and Jill have to navigate a guest list of war heroes and supposedly retired spies to find out which one is a murderer . . . and a traitor.
