James shaded his eyes and looked up at the red brick building, trying to guess which of the fourth-floor windows was Isobel's. The curtains were still drawn on all of them, even though it was almost 10:00 a.m., but at this point he didn't care about waking her. He just wanted to tell her what he had learned from Professor Lin and make sure she was safe - not necessarily in that order. It troubled him that Isobel, who he knew was addicted to her iPhone, hadn't picked up his calls last night or returned the message he'd finally left. His first thought was that she was with Hugh, and he'd had to work hard to master the strange mix of emotions that overtook him. But as the evening wore on, he felt certain that even if she were with that twerp, she'd have checked her phone at some point. On the other hand, he reasoned, if she was with Hugh, it might have been difficult for her to steal a moment to call him back.
