Dr. Jonathan Lyons, a seventy-year-old biblical scholar, believes he has found the rarest of parchments - a letter that may have been written by Jesus Christ. Stolen from the Vatican library in the fifteenth century, it was assumed to be lost forever.Under the promise of secrecy, Jonathan attempts to confirm his findings with several other biblical experts. But on the eve before his own murder, he confides to Father Aiden O'Brien, a family friend, that one of those whom he trusted most is determined to keep it from being returned to the Vatican.The next evening Jonathan Lyons is found shot to death in his New Jersey home. His daughter, twenty-seven year old Mariah, finds her fathers body sprawled over his desk in his study, a fatal bullet wound in the back of his neck, and her mother, Kathleen, an Alzheimers victim, hiding in the study closet, incoherent and clutching the murder weapon. The police suspect that Kathleen, who in her lucid moments knows that Jonathan was involved with a much younger woman Lily Stewart, has committed the murder.But Mariah believes that the key to her fathers death is tied to another question: Where is the missing parchment? Whom, among his close circle of friends, might he have consulted? And did one of them kill to keep possession of the letter? What Mariah doesnt know is that there was an eyewitness to the murder, someone whose unwise attempt to blackmail the killer begins a new circle of death, with Mariah as the ultimate target of one persons obsession with a priceless historical treasure.
