Spring has come to the abbey, and the community is busily preparing for the May Day weekend and the arrival of Boy Scouts who will hold their annual camp on the abbey grounds. When a Boy Scout named Antoine is sent home in disgrace, Fr Gabriel accompanies him to his house, which has become the scene of a violent crime. Antoine's father, Charles, has been found dead, apparently killed during a botched burglary. Suspecting there was more to the crime than what first meets the eye, Fr Gabriel joins forces with Inspector Applegate to learn about Charles Nicholson, a quiet family man with no obvious enemies. The victim, however, had been married to a fiery French resistance fighter, a union that had caused considerable excitement in the sleepy village. It doesn't take long for Gabriel to notice that Brigitte Nicholson's life - and courageous death in wartime France - has had a dramatic effect upon her surviving family. Gabriel's quest for the truth leads him into the brutal world of Nazi-occupied France, where resistance fighters like Brigitte were betrayed by their most trusted friends. Could Brigitte's betrayer and Charles' killer be one and the same person? And could the shadowy figure menacing Gabriel be the murderer he is trying to hunt down? This sixth installment of the Father Gabriel series explores the murky world of wartime treason, profiteering, and betrayal. The story also involves the return of some characters from earlier in the series.
