The Devil's Mark (The Scorpion Book 1)

 Rome the beautiful is dying, the symbol of civilization falling, the
empire burning. Hidden from massacres and looting, a strange meeting
is held by nine families who share the Roman Empire. To retain their
power, they decide to support a new
religion—Christianity—as well as its representative, the
pope. But who are these 9 mysterious families? Later, much later,
it's the Renaissance. Christianity prospers. A brigand called
"the Scorpion” makes a living by unearthing relics in the
depths of the Roman catacombs, which he sells at high prices to
princes and bishops. Trebaldi, a powerful cardinal, takes an interest
in this Scorpion, who is either a creature of the devil... or a
witness to a cursed era who must disappear...This two-volume book
includes "The Pope's Secret".

The Scorpion - Volume 3 - The Holly Valley

 Betrayed by the beautiful Ansea Latal, the Scorpion has been captured by the Turks. But he cannot afford to tarry: Rochnan and his monks are close on his tail, Ansea is on her way to Cappadocia to find the true cross of Saint Peter, and, back in Rome, Trebaldi is preparing his reign of terror. As a prisoner or a fugitive, alone or in the reluctant company of people who have sworn his death, the Scorpion will have to reach Karabas before the agents of the Nine Families and discover the truth hidden deep inside the Holy Valley.

 

The Treasure of the Templars (The Scorpion Book 2)

The lights of Rome have dimmed. When the Scorpion and his friends get
back to the Holy See, it is a place of fear and death they find, a
city cowering under Trebaldi’s boot. Their only chance to destroy the
Pope’s power is to heed Rochnan’s last words and look into the past
of the Scorpion’s mother. Dodging warrior-monks and Inquisitors, they
begin to unravel a story that could yield some answers too horrible
to contemplate…

 

In the Name of the Father (The Scorpion Book 5)

an army is expensive. To pay his men before their loyalty begins to
slip, the Pope must rely on the financial assistance of European
monarchs—and a large sum in gold is coming to Rome. But such a convoy
is tempting to many! Trebaldi, the Nine Families, thieves and
conspirators... And all figure they can use the Scorpion against each
other to obtain what they want.
