From New York Times bestselling author Susanna Kearsley comes a story of intrigue, espionage, and a murder concealed since WWII—a long-forgotten crime that someone will stop at nothing to keep buried.

When an elderly man strikes up a conversation with her on the steps of St. Paul's, offering to tell her about an old murder and making an oddly familiar comment about her grandmother, journalist Kate Murray is too busy to listen. But she soon wishes she had. Shocked by Andrew Deacon’s unexpected death, she wonders who he was, and what he knew, and how he is connected to her family.

Intrigued by the tale never told, Kate becomes drawn into an investigation, uncovering secrets about the grandmother she thought she knew and a man she never did. She’s soon caught up in a treacherous whirlwind of events that pulls her back into her grandmother's mysterious wartime past and across the Atlantic as Kate tries to retrace Deacon's footsteps. Finding out the truth is not so simple, however, as only a few people are still alive who know the story...and Kate soon realizes that her questions are putting their lives in danger.

Stalked by an unknown and sinister enemy, and facing death every step of the way, Kate must use her tough journalistic instincts to find the answers from the past in order to have a future.
