Loyalty and betrayal, hope and despair, One Moonlit Night tells the captivating story of a husband and wife separated by secrets as well as by war.

Forced to leave their family home in London after it is bombed in the Blitz, Maddie and her two young daughters take refuge at Knyghton, the beautiful country house in Norfolk where Maddie's husband Philip spent the summers of his childhood.

But Philip is gone, believed to have been killed in action in northern France. Despite overwhelming evidence to the contrary, Maddie refuses to give up hope that she and Philip will some day be reunited.

Arriving at Knyghton, Maddie feels closer to her missing husband, but she soon realises that there's a reason Philip has never spoken to her about his past. Something happened at Knyghton one summer years before. Something that involved Philip, his cousin Lyle and a mysterious young woman named Flora.

Maddie's curiosity turns to desperation as she tries to discover the truth, but no one will speak about what happened all those years ago, and no one will reassure her that Philip will ever return to Knyghton.
