Dr. Jonathan Lyons, a well-respected academic, has a stroke of luck when a previously missing ancient artefact - a highly valuable parchment - falls into his hands.
Stolen from the Vatican in the fifteenth century, it was assumed to be lost forever - until now.
Unsure of his next move, Dr. Lyons shares his discovery with a select few but, with so much money at stake, can he trust the people he's told?
Things take a turn for the worse when Jonathan is found brutally murdered in his own home.
Then, as secrets in his personal life come to light, his wife, who suffers from Alzheimer's, is soon implicated.
It now falls to the couple's 27-year-old daughter, Mariah, to uncover the true motive behind her father's death.
But the tangled web of secrets has spread much further than she knows.
With someone still hell-bent on getting hold of the priceless document, will Mariah succeed in finding justice for both her father and her mother without putting her own life in terrible danger?
