I think someone upthread, or maybe in a PM, had expressed interest in the Dublin Murder Squad series by Tana French. (IMS, I think a book club was involved ??? but can't find it now.) In any case, here's the fourth title in the series, Broken Harbor, on sale at $1.99 at Kindle and Kobo US.

Spoiler:

Mick “Scorcherˮ Kennedy is the star of the Dublin Murder Squad. He plays by the books and plays hard, and thatʼs how the biggest case of the year ends up in his hands.

On one of the half-abandoned “luxuryˮ developments that litter Ireland, Patrick Spain and his two young children have been murdered. His wife, Jenny, is in intensive care. At first, Scorcher thinks itʼs going to be an easy solve, but too many small things canʼt be explained: the half-dozen baby monitors pointed at holes smashed in the Spainsʼ walls, the files erased from the familyʼs computer, the story Jenny told her sister about a shadowy intruder slipping past the houseʼs locks. And this neighborhood—once called Broken Harbor—holds memories for Scorcher and his troubled sister, Dina: childhood memories that Scorcher thought he had tightly under control.
