Re: The Gathering Darkness (the Connor series) - Dirk B.
Impressions: It's trying too hard to conceal the identity. Is it worth the effort? There is no one in the story it could be that would carry any shock value-- not even the detectives or the pope (though the latter would be humourous given the level of physical activity). The reason for this lack-of-shock factor is the story hasn't "sold" us that it isn't any given person. If this was a movie, I'd suggest the dark figure was Connor from the future, but yes, it could be anyone even one of the victims.
Maybe take another swing at it?
