In this second mystery from Tana French, the murder of a young woman drops like a stone into the world of her four friends, and of the detectives investigating it. Ripples spread, unsettling all of their lives and certainties and waking deeper currents.

I read this book and French’s earlier one, In the Woods, a few years ago, long enough ago that the details have faded but my memory of liking them hadn’t. That made them a good choice for listening to in the car on a couple of long trips: the story would come back to me enough that I wouldn’t have to concentrate hard to follow it but I could enjoy again the writing I loved.

The first person point of view makes these two books especially vivid. In the Woods is narrated by Rob Ryan, a detective in the Dublin murder squad. With The Likeness, his former partner Cassie Maddox, who has moved to the Domestic Violence unit, is pulled back and plunged almost against her will into investigating the death of Lexie Maddox, found stabbed in a remote cottage.

Frank Mackey, her boss from when she worked underground, back before the murder squad, persuades Cassie to impersonate the dead woman. The two young women look almost exactly alike, rare enough, but even more astonishing is that the dead woman had assumed the identity of Lexie Maddox, one of Cassie’s undercover identities. Mackie tells Lexie’s four friends that she survived and then sends Cassie in to live among them, to see if she can identify a suspect.

This is the part I loved. The five of them, PhD students at Trinity, live in a dilapidated country mansion which Daniel has inherited. He and Abby, Rafe, Justin, and Lexie are completely self-sufficient socially, a tight unit: innocently playful and sweet together, they become an armored phalanx among strangers.

Even just driving up to the house and seeing them on the steps Cassie is thoroughly charmed, in the deeper sense of being almost under a spell. It all seems so familiar. And the golden weeks that follow—working on the house together, dancing to Abby’s singing, reading and talking in the evenings—tempt Cassie with their promise of a different life. I was reminded of the beginning of Brideshead Revisited when Charles Ryder falls in love with Sebastian’s life. French captures so well the fun of being part of a tight group of friends, when you’re young and it’s all happening for the first time and everything seems unbearably sweet.

Even as Cassie slips more deeply into their easy camaraderie, though, she is looking for anything that might point to a suspect. She explores the local folks’ hatred for the house’s inhabitants and Daniel’s cousin’s frustration over not inheriting the house himself. She begins to see cracks in the family. She hears secrets whispered at night, notices Justin’s mounting fears and Rafe’s increased drinking.

There are plenty of questions to keep my mind buzzing, not just the big ones of who killed Lexie and why, but questions about each of the four friends, about why Lexie needed a new identity, about Mackey’s intentions and what Cassie herself will choose to do at each turn.

And the story is hauntingly beautiful at times, such as when we are drawn into the world these friends have created, their hour of splendour in the grass. There is much here about innocence and responsibility and the desire for freedom that can sometimes drown out everything else. And Cassie, with her strong moral code, her chameleon-like abilities, and her doubts and temptations makes an excellent traveling companion.
