The significance of the title is PI Patrick Kenzie’s love for his partner, Angie. This stands in stark contrast to the unholy relationship between some other characters in this tale. Billionaire Trevor Stone wants the PI pair to track down his daughter. Time is of the essence as the old guy is on death’s door. Adding flavor is that Patrick’s mentor had been hired to find her already and has now gone missing himself. Lehane gives us a nifty look at a Grief Counseling organization that abuses its clients trust then makes them pawns of its criminal desires. It also hooks up with a cult-like religion that features aggressive proselytizers that seem more like gang-bangers. The dynamic duo suffers the usual physical damage, but remain alive. There were a fair number of twists and turns here. It seemed more than in the earlier two books. Although I enjoyed the book and would recommend it, I was not as taken as I was with the prior one. Perhaps I am growing a little weary. Child abuse figured in this one as well, but not, ultimately, as a significant factor.
