The Blood Road by Stuart MacBride
My rating: 4 of 5 stars
Logan's life seems to be settling down... maybe. He's in a relationship, on meds to deal with the ptsd hallucinations, and Roberta Steele is not working in the same department. Of course that goes awry when the understaffed police department needs him to cover an investigation that only tangentially relates to Professional Standards. The usually cast of characters is here, used well and seemingly evolving with each book (not usual in many series). As for the mystery, the whodunnit part isn't overwhelmingly obvious but sharp readers will figure it out.
