The Trespasser by Tana French
I love the Dublin Murder Squad series, but the latest book is probably my new favorite. The narrator of The Trespasser is Antoinette Conway, the tough, prickly detective who teamed up with Stephen Moran in the most recent book, The Secret Place. Conway has been continuously sexually harassed since joining the murder squad, and it has made her paranoid and distrustful of her fellow detectives. She’s constantly wondering whether other detectives are undermining her investigation, but in this case she might be right. “Daddy issues” are also a theme, as a missing father turns out to be one thing Conway has in common with the victim. The majority of the action plays out in extended interviews of the suspects and witnesses, delving deep into each subject’s psyche, as Conway instantly analyzes each answer and tweaks her role-playing accordingly.
