Catching a killer is dangerous—especially if he lives next door 

From the hugely talented author of The Kind Worth Killing comes an exquisitely chilling tale of a young suburban wife with a history of psychological instability whose fears about her new neighbor could lead them both to murder . . .

Hen and her husband Lloyd have settled into a quiet life in a new house outside of Boston, Massachusetts. Hen (short for Henrietta) is an illustrator and works out of a studio nearby, and has found the right meds to control her bipolar disorder. Finally, she’s found some stability and peace.

But when they meet the neighbors next door, that calm begins to erode as she spots a familiar object displayed on the husband’s office shelf. The sports trophy looks exactly like one that went missing from the home of a young man who was killed two years ago. Hen knows because she’s long had a fascination with this unsolved murder—an obsession she doesn’t talk about anymore, but can’t fully shake either.

Could her neighbor, Matthew, be a killer? Or is this the beginning of another psychotic episode like the one she suffered back in college, when she became so consumed with proving a fellow student guilty that she ended up hurting a classmate?

The more Hen observes Matthew, the more she suspects he’s planning something truly terrifying. Yet no one will believe her. Then one night, when she comes face to face with Matthew in a dark parking lot, she realizes that he knows she’s been watching him, that she’s really on to him. And that this is the beginning of a horrifying nightmare she may not live to escape. . .


My thanks to William Morrow for sending me a copy of this book at no cost in exchange for an honest review. All opinions are my own and are not influenced by the publisher. 

Before She Knew Him is a quick and super creepy read. I will preface this review by saying that I think the synopsis is slightly misleading. It asks: Could her neighbor, Matthew, be a killer? Or is this the beginning of another psychotic episode like the one she suffered back in college, when she became so consumed with proving a fellow student guilty that she ended up hurting a classmate?” You may be led to believe that there’s some mystery surrounding whether or not Matthew is actually a murderer, and there truly isn’t.

The novel is told through multiple point of view characters, one of which is Matthew himself, so it is revealed very early on that Hen’s suspicions about him are correct. So what’s sort of framed in the synopsis as a mystery for the reader is more Hen’s own internal struggle with herself and her struggle to be taken seriously as someone with a mental illness. Hen may remind readers a lot of Anna Fox from The Woman in the Window or Rachel Watson from The Girl on the Train. Mira, Matthew’s wife, is also a point of view character for a few chapters, and these chapters were a lot of fun. It was interesting to see Matthew through her lens and watch how her impression of him slowly changed throughout the story. 

Gendered violence is a major theme throughout the book; men who hurt women and men who hurt other men to protect women are central to most of the violence which occurs. Given the subject matter, I’d like to give a trigger warning for this novel in regards to sexual violence, with the caveat that it never becomes graphic or overly descriptive in this  regard.

Overall, the story was fast-paced, deliciously creepy, and has just enough twists and turns to keep the reader super engaged without veering into ridiculousness. Swanson juggles various point of view characters without the novel feeling overly crowded or jumbled. I would definitely recommend this novel to fans of A. J. Finn or Paula Hawkins!
