Erik watched in amusement from behind the mirror as the little Vicomte searched for the Voice behind curtains and closet doors, like a child playing a game.

His Christine would not say that she loved him, but she must! For she had sent this would-be suitor away without hesitation, and told Erik that she had given him her soul. It was such a beautiful thing, her soul, but Erik was greedy. He wanted much more than that.

His mirth turned to suspicion when the young man would not leave. Though his voice trembled as he challenged his unseen rival, the boy stood firm.

Oh, this would not do at all.
