The Trespasser by Tana French

Detective Antoinette Conway grew up mixed-race and without a father in conservative Dublin, Ireland, so she’s used to not fitting in. She has always worn her differences defiantly and proudly, and styled herself a lone wolf, happy to be an outsider. She didn’t think she would fit right into Dublin’s all-male Murder squad, but she didn’t expect the level of harassment she’s receiving—pee in her locker, spit in her coffee, her paperwork thrown away and her cases jeopardized. It’s clear to Conway that everyone in the squad wants her out except for maybe her rookie partner, Steve Moran.

As the harassment begins to take a toll on Conway’s psyche, she and Moran are handed a seemingly straightforward murder—the victim, Aislinn Murray, led a boring life and there’s only a single suspect, her new boyfriend, Rory. The case should be an open-and-shut domestic, but nothing quite adds up. As their investigation is blocked at every turn by members of their own squad, Conway and Moran begin to suspect that finding Aislinn’s killer may lead them to a dangerous truth.

The Trespasser combines beautiful writing and intense psychological drama to create a literary mystery that draws the reader in completely and doesn’t let go until the final page. Though it is book six in French’s Dublin Murder Squad series, this novel is more than capable of standing alone.
