Ocean's Breath Plateau i.xii : who was found dead on the phone

When RedHawks came for her... Who had come? Did they know where she was? And what was worse... did they know and not tell him?  

Why not let her go home?  He asked, his voice tight with the implications this brought.  If they helped her to escape, then she should be safely on her way back to the plateau, not way out here near the coastline.  Something was wrong here, and as soon as he found her, he was going to get to the bottom of it.
