Olivia Denis is a content young wife with a carefree life in late 1930s London. Then her world is shattered with the violent death of her husband, Reggie. The police want to call it a suicide and close the case, but Olivia knows Reggie couldn't possibly have fired the fatal shot. Further mysteries surface surrounding her husband's death. Did the trustworthy Foreign Office employee betray government secrets? Was his murder linked to the death of a German embassy clerk the same night? And who searched their flat?

Olivia Denis is hesitant to help an old family friend get ready for her wedding outside London. The so-called friend is a master at using people. As a young widow trying to find her way through a new romantic relationship, Olivia would rather avoid the large party. She definitely didn't plan to find the bride's grandfather stabbed to death. The cruel, enormously rich aristocrat had changed his will only the day before, angering all his children.

But on her first visit to Mimi's new Mayfair house of haute couture, Olivia finds something else - the body of an unknown man. Mimi and her three French assistants say they don't know the man, but is that true? As Olivia spends time around the salon, she learns at least one of the women knew the dead man and all four women are lying.

Olivia Denis discovers her father kneeling over the body of a man...a man who supposedly drowned in the Channel years before. Olivia wants to ring for help, her father wants to hide the body, but a mysterious phone call brings Scotland Yard to the murder scene. Olivia can't stand by and let her maddening, disapproving father hang. To prove his innocence - and learn his secrets - she must work with a master spy.
