A dizzying romance, which grew into a fleeting acquaintance between Kay Lansing, a modest librarian from New York, and Peter Carrington, the heir of an old aristocratic family, culminated in a wedding. But before the couple had time to return from their honeymoon, the young husband was arrested on charges of murdering his longtime girlfriend, who had gone missing twenty-two years ago. All the evidence points to him, and only Kay believes that Peter is innocent. The heavier the weight of evidence that seems to expose her husband as a murderer, the more Kay becomes convinced that the key to solving this crime lies in one episode from her own past.
