Though hooded and cloaked, Nicolette trembled. The chill of the January afternoon pierced her through, but it was fear, more than the cold, that made her limbs shake. Having just crossed over to the Left Bank, she glanced back over her shoulder and saw the towers and spires of the royal palace across the Seine. She felt as if hidden eyes there were watching her. Could anyone on the palace wall have seen her walk over the Petit-Pont?
Not Amalric. He was still in the south, the King having just appointed him seneschal for Beziers and the surrounding country. But he had so many agents in Paris and allies at court. Except for Agnes, all the servants in the Gobignon town house were loyal to him. His aunt, Queen Blanche, was forever praising him to all who would listen. If Nicolette were involved in scandal, the White Queen would be furious, and would see to it that word reached Amalric. And if indeed he found out about her meeting the troubadour? Just a message, a song, let alone a meeting like this one, could mean death for her and Orlando.
I should turn around right now, cross this bridge, and run back to the palace. The streets of the Latin Quarter were crawling with ruffians and criminals - it was insane for her to be walking here alone after sunset. The sight of the small knife she carried under her cloak might deter an attacker, but then she would be discovered.
If I screamed for help, the whole palace would find out. Blanche would demand to know why I was here. No, she thought, her blood turning to ice, she would know why.
But those eyes of his? to look into them again, was that not worth any risk?
She stood, vacillating, in the shadows by a wooden house that overhung the Rue Saint-Jacques. I must see Orlando, she thought. Over a year now, and I have not been able to forget him. She longed just to be alone with him and have him take her in his arms.
