The Hunter by Tana French

 French returns to the location of her last novel, The Searcher, in this novel.  It's the same rural Ireland with Cal, Trey and Lena and the villagers.  Trey is living a more settled life these days.  She works with Cal on carpentry and they have gotten a good reputation.  Trey is going to school and doing well.  Lena and Cal are now a couple.

But things are about to change.  Trey's father shows up after years away in London.  He has brought a London millionaire with him or at least that's what he says.  The two are hunting gold and sure that it can be found in the land surrounding the village.  All they need is a small investment from those whose land might hold the gold.

Soon there's gold fever in the village.  But who's conning who?  Are the Londoners taking advantage of the rural men or do those men have a trick or two up their sleeves?  Cal takes part enough to try to protect Trey without telling her as she is sure she is grown up enough to take care of herself.  When the other London man is killed, Trey starts to play a dangerous game that would give her revenge on the village for her brother's death a couple of years ago.  Cal is frightened for her and not sure how to help.  

Tana French has been a five star author since her debut with the Dublin Murder Squad series.  In these most recent books, she delves into the mindset of rural Ireland and those who live there.  Cal is a former detective and that gives him some insight into what is going on, and he and Lena are fiercely protective of Trey who they think is worth more than the reputation her family has due to her worthless father.  Can the murder be solved before more death visits the village?  This book is recommended for mystery readers.
