Something had spoken in him. There was a voice, subtle and exultant, that reared itself phantom-like amid his thoughts. It was urging him to enter the locked door, to fall at the feet of the woman inside the room.

“Ah,” he mused, “she lures me. I believe her guilty ... a murderess, a Messalina. And the fact lures me. De Medicis hail her. De Medici ghosts inside me prostrate themselves devoutly before a kinswoman—a woman whose hands are red with murder.... An impulse toward obeisance stirs in me.”
