Book Synopsis: After a harrowing stay with Catherine's in-laws in Scotland, Catherine and her husband, Edgar, have returned home with their two small children to live a life of peace at last -- or so they hope. But soon the safety of those they love is questioned as anti-Jewish sentiment begins to grow in Paris. Raised Catholic by her father, Hubert, who poses as a Christian while practicing Judaism in secret, Catherine fears that the violence of the most recent crusade will repeat itself, victimizing members of her family. but before she can put too much thought into that, fate interrupts.Catherine's estranged younger sister, Agnes, has returned to Paris with the news that she has been promised in marriage to a German lord. Bitter about their religious differences Agnes wants no part of Catherine or Hubert -- except for the sizable dowry that Hubert can provide. When Catherine and Hubert arrange for Agnes to be escorted to Germany with her dowry, they assume that they have seen the last of her.
But then one of Agnes's escorts returns to Paris with terrible news: Agnes's new husband appears to have been murdered by poisoning, and Agnes is the prime suspect. In spite of their differences, Catherine believes in her innocence, and knows that she must do everything she can to save her sister's life. And when Catherine and her brood travel to Germany to begin sleuthing in a dangerously anti-Semetic climate, it becomes clear that Catherine and Edgar's long-dreamt of life of peace remains in the distant future -- if they live to see it at all.
