Knots and Crosses

sex cursing
there's a killer in the loose
turns out to be the army buddy of the policeman

This mystery, set in Edinburgh, is all about child abductions and PTSD. Major trigger warnings. The first in the Inspector Rebus series, John Rebus is a flawed human, suffering privately from PTSD and serving as a Detective Sergeant. Rankin gets the characterizations spot on, even to the near teen daughter. There were some loose ends in the personal life, that I trust will play out in upcoming stories. Very British/Scottish, to the point that some references went over my head.
