He goes directly to the ballroom, making his way to the center of the dance floor. He takes Celia’s arm, spinning her away from Herr Thiessen.Marco pulls her to him in an emerald embrace, so close that no one distinction remains between where his suite ends and her gown begins. To Celia there is suddenly no one else in the room as he holds her in his arms. But before she can vocalize her surprise, his lips close over hers and she is lost in wordless bliss. Marco kisses her as though they are the only two people in the world. The air swirls in a tempest around them, blowing open the glass doors to the garden with a tangle of billowing curtains. Every eye in the ballroom turns in their direction. And then he releases her and walks away. By the time Marco leaves the room, almost everyone has forgotten the incident entirely. It is replaced by a momentary confusion that is blamed on the heat or the excessive amounts of champagne. Herr Thiessen cannot recall why Celia has suddenly stopped dancing, or when her gown has shifted to its current deep green. “Is something wrong?” he asks, when he realizes that she is trembling.
