On The Fifth Day

ISBN: 978-0425216286

When a Catholic priest dies in mysterious circumstances on a remote tropical island, his estranged brother, Thomas, sets out to learn what arcane research the priest was pursuing which might have gotten him killed. Refusing to believe the rumors of terrorism which are gathering around his dead brother, Thomas begins an archaeological quest through southern Italy, trying to make sense of the curious images he finds, and their link to a dreadful place long shut away from the public eye. But if he is bent on uncovering the secret of his brother’s death, there are others, as strange as they are sinister, who will do everything in their considerable power to make sure that does not happen.


"A.J. Hartley is a rare discovery: a writer capable of challenging a reader as much as he thrills . His latest novel, ON THE FIFTH DAY, careens at a breathless pace from dark crypts to exotic sunlit shores. Full of historical mystery, rife with intrigue and suspense, here is a tour-de-force sure to keep pages turning deep into the night."

- James Rollins, New York Times bestselling author of Black Order
