I'm re-reading the Repairman Jack series currently, the Adversary cycle, and a few of the novels and short stories from the "Secret History." I'm on By the Sword right now. But I got to thinking, since the Ally, up to Harbingers was trying to prune Jack's spear, I thought that the Ally might have be somewhat behind the events in The Haunted Air. The stones in Menelaus Manor were revealed to have been taken from the Keep, which I believe have some sort of spiritual holding power, as the complete configuration held Rasalom for (going from memory, I hope it's accurate) 500 some odd years, the murdered children stayed on in the house as well as one of the Kenton brothers (I think it was Lyle but I'm not sure) from the effect of the stones, and (I haven't gotten to the point of re-reading Reprisal yet) I believe that Rasalom (as "Sara Lom") murdered the kid whose voice torments Father Ryan on the telephone using the power of the stones. It is my belief that the Ally used the murdered girl's spirit in an attempt to take Gia's baby.
Or, it was a "tainting" of the Keep stones by "Sara Lom," who is also a necromancer, which means that the Ally and the Otherness were working together (at least had complimentary goals) to a) prune Jack's spear and b) cause pain and discontent through sheer mayhem.
BTW:
I noticed a couple of discrepencies in Infernal. I marked the pages but my coworker is reading the series for the first time (he's on Infernal now) and I only remember one of them off the top of my head. Abe makes a comment about not hearing of Johnson, NJ, when, as we know from Jack: Secret Histories, he met young Jack there at the antique shop. This is probably because FPW wrote this book prior to the young adult series so I take inconsistencies like that in stride. Hey, it's a great series regardless. And, I was and still am stoked that FPW tied in Black Wind to RPJ. That was one of my favorite stand alone books.
Anyone have any speculations on my The Haunted Air theory?
