Memory Man finished

I will definitely read another by Baldacci.  This one was great for 75%, but endings matter, and I didn't find this one satisfying.  Our murderer--and intrasexual raped in her small Utah town as a teenager--has been talked into symbolically killing her victimizers by shooting up another school in another town.  That's a stretch. She hates Decker because, at a counseling session, he said he wanted to be a cop and help people. Another stretch. Her accomplice is really a murderer/thief with a phony website supposedly for victims to find ways to revenge themselves. Decker blames himself for the murders because he mentioned wanted to be a cop and thereby set off all these terrible events . . .  a stretch. Decker understands why Billy killed his family and sort of forgives him/her. Another huge stretch. 

The writing is great; the plot . . . not so much
