The voice was a loud whisper, he should have expected something since it might as well have been said by someone right next to him. Still, he stopped dead in his tracks and looked up. He'd been by this house a thousand times - he must have, but this was the first time he'd ever actually seen it, per se. One of the windows was open a crack, and he swore he saw a face in it. It was a girl he'd known when he'd first come to London.
"Er..." he wasn't sure of her name, but something about the way she'd called him filled in with utter dread; he was sure she was in some kind of terrible danger.
"Come quickly, come quickly, 'fore he comes back!" She seemed more desperate this time. Izzy headed her words and ran towards the door, very surprised to find that he wasn't just being a fool and that it was open.
As soon as he got inside, the door slammed shut behind him, though by this time he wasn't paying attention. He ran through the house to the room where he thought the window might have been, and then the one next to it when he didn't find her there, and then practically the entire floor when he didn't find her there either.
That had always been the problem with Izzy. He could be terribly gullible when he thought he was needed.
