" Niccolo Machiavelli folded his arms across his chest and looked at the alchemyst. “I always knew we would meet again,” he said in French. “Though I never imagined it would be in these circumstances,” he added with a smile. “I was certain I’d get you in Paris last Saturday.” He bowed, an old-fashioned courtly gesture as Perenelle joined her husband. “Mistress Perenelle, it seems we are forever destined to meet on islands.”
“The last time we met you had poisoned my husband and attempted to kill me,” Perenelle reminded him, speaking in Italian.
Over three thousand years previously, the Sorceress and the Italian had fought at the foot of Mount Etna in Sicily. Although Perenelle had defeated Machiavelli, the energies they unleashed caused the ancient volcano to erupt. Lava flowed for five weeks after the battle and destroyed ten villages.
“Forgive me. I was younger then, and foolish. And you emerged the victor of the encounter. I carry the scars to this day.”
“Let us try and not blow up this island,” she said with a smile. Then she stretched out her hand. “I saw you try to save me earlier. There is no longer any enmity between us.”
Machiavelli took her fingers in his and bent over them. “Thank you. That pleases me. "
