It isn't until fellow group member Sean Conner approaches him after a meeting that Doug realizes the trouble is just beginning. Sean has discovered in his attic what can only be called a scrapbook of a murder victim, but he has no recollection of the girl's identity or why he might have gathered this information.

When he discovers that he had a personal connection to this case, suddenly he's questioning everything he thought he knew about the case, about Sean, and about his own past.
