The Trespasser by Tana French **** (of 4)

Detective Antoinette Conway has finally achieved her goal of reaching Dublin's murder squad, but Antoinette is not only the first woman to enter Ireland's male bastion of investigators, she is also the daughter of a dark-skinned (absentee) father. Conway is hazed mercilessly by her fellow officers who spit in her coffee when gets up from her desk, pat her backside, pee in her locker, throw away her files instead of handing them in, and mess with her computer. 

Conway proudly stands her ground and when she and her partner are handed what should be a routine murder case -- girlfriend is reported dead in her living room right after her boyfriend is seen leaving the house in a hurry -- she does a full-on investigation. 

As mysteries go, this one is just the right amount of tortuous to make it a page turner, but what Tana French does best is introduce us to the routine doubts and in-our-head-rebuttals that all of us endure. She does it by introducing complex, slightly flawed characters (just like all of us, they get grumpy when they are tired, for example), their ways of speaking, and their personal lives so accurately that we can actually visualize them. The reader for this recorded book makes the people at the heart of this drama so realistic you will be speaking with an Irish accent for days after the case is solved.
