Post-war London should have been safe. It wasn't.
It is May 1957. In London eight friends gather for a party. They are all displaced persons who have survived the worst World War II could throw at them. This gathering will be a time to share the fragile joy of liberty. But before the night is out, one of them will be dead. Who would commit such a crime? And why? Detective Andrew Perry, together with his naive sidekick, James Cook, is assigned the unenviable task of searching through the horrific memories of the survivors, looking for the beginning of the thread that will lead him to a solution.
