But exactly who?

Arwen's brows furrowed in a deep frown at Gianna's words. Sensing her skepticism, Gianna quickly explained what she was trying to say. 

"Wenna, I know this doesn't seem to make much sense, but there is a real possibility that she was behind it," she said, not waiting for even a second before continuing. "I mean, those men were seriously following you with the intention of harming you. And who else would want to harm you, except Delyth? You were an obstacle in her way. Your engagement with Ryan was the only thing stopping her from having him all to herself. Without you, she would have had him easily. She had every reason to want you out of the picture." 

"Causing trouble for me is one thing, Anna. But hiring people to hunt me down and kill me? That's something sinister. Delyth couldn't stoop that low … could she?" Arwen hesitated, struggling to accept such a cruel possibility.
