"I do," Ivy said quietly, and heard Gregory draw in his breath. "Go on," she said.

"When we got to the bottom, we still had to get over another fence. I asked what was going on, but Tristan wouldn't tell me. He just said we had to help you. So I started climbing, then I kind of messed up. I thought because Tristan was an angel we could fly"-Gregory got up and started pacing around the bedroom-"but we couldn't, and we fell off the top of this high fence."

Ivy glanced down at her brother's wrapped ankle. His knees were cut and bruised.

"Then we heard the train whistle. And we had to keep going. When we got closer we saw you on the platform. We shouted to you, Ivy, but you didn't hear us. We ran up the steps and over the bridge. That's when we saw the other Tristan. The one in the cap and jacket, just like in your picture," he said, pointing to it. Ivy shivered.

"So," Gregory said, "angel Tristan is in two places now-with you, and on the other side of the tracks as well. He's playing a trick on Ivy, calling her over to him. It wasn't a very nice trick."

"Tristan was with me," Philip said.

"Then who was across the tracks?" Gregory asked.

"A bad angel," Philip replied with complete certainty. "Someone who wanted Ivy to die."

Gregory blinked.

Ivy sank back against her headboard. As bizarre as Philip's story sounded, it seemed more real to her than the idea that she had taken drugs and thrown herself in front of a train. And the fact remained that somehow her brother had gotten there and he had pulled her back at the last moment. The engineer had seen the blur in front of his train and radioed in that he could not stop in time.

"I thought you saw Tristan," Philip said.

"What?" Ivy asked.

"You turned around. I thought you saw his light." Philip gazed at her hopefully.
