St. Joseph's Hospital, Father Jake Austin encounters the "Night Nurse," the ghost of a woman killed in a fiery car crash decades earlier. The evidence suggests she was murdered, and Jake tracks down her killer in the coldest of cold cases.

The Superior General of his Catholic order learns of his expertise in solving mysteries and sends him to New Orleans to investigate a priest suspected of being both a sexual predator and a thief. As he brings the investigation to a close, he's anxious to return to his parish to resume his normal duties.

It is, however, the calm before the proverbial storm. A car bomb explodes outside his father's house and another bomb severely injures his associate pastor, and suddenly he is embroiled in a vendetta that endangers those he loves and will entirely change his life and his future.
