The Cold War is over, but The Wolf is still at the door.

When Violet Lundy isn't cleaning rooms at Happy Hills Assisted Living Facility, she loves spending her free time with resident Rainer Kopecek. Hearing his stories of the dangerous life he led behind the Iron Curtain in East Berlin makes her own life seem more tolerable. But when Rainer is found dead and his room in disarray, Violet suspects foul play.

Dr. Henry Silverton lives among his books, teaching and writing about the Cold War. A letter about an East German traitor known only as "The Wolf" propels Henry out of academia and into Violet's life. Together, they embark on a perilous quest to uncover the truth about Rainer's death and the traitor's identity.

Can Violet and Henry uncover the secrets of the past before one of them ends up as The Wolf's next victim?
