A remarkable trio whose lives were cracked wide open by their husbands’ crimes unite to catch a serial killer in this dazzlingly captivating novel.

Beverley, Elsie, and Margot are not your average housewives. They are all wives of convicted killers. During the sun-drenched summer of 1966, the three women form an unlikely friendship after the discoveries of their husbands’ brutal crimes. With their exes—some of California’s most infamous serial killers—dead or behind bars, they are attempting to forge a new future for themselves.

Headstrong Beverley compulsively tries to maintain control of everything around her, all while raising two children. Bookish Elsie fights day in and day out for the chance to make a name for herself in the newsroom, working among men who sneer at her career goals. Glamorous Margot refuses to take anything seriously and devotes all her energy to upholding the appearance that everything is fine—anything to quell the shame from her husband’s deceit.

They know people look at them and think only one  How could they not have known, when their husbands were right under their noses, committing horrific crimes? How much guilt is theirs to carry? And yet when a string of killings hits the news, the three women—underestimated, overlooked, shrewd—decide to get to work.  After all, who better to catch a killer than those who have shared their lives and homes with one?

At once a riveting portrayal of shattered trust and a story of gripping suspense, The Secret Lives of Murderers’ Wives is a testament to the intricacies of women’s lives and how the deep bonds of female friendship can empower, uplift, and lead us to endure.

I received an advance copy of this book courtesy of the publisher. All thoughts are my own.

The title alone is what convinced me to request this on NetGalley. It really sells itself.

This one is a fun, character-driven serial killer mystery set in 1966 California, and it scratches a very specific itch if you like your thrillers with a side of historical detail and genuinely good ensemble work.

Beverley, Elsie, and Margot have one very specific thing in common: their husbands are convicted killers. Now they’re trying to rebuild their lives in the wake of crimes they swear they didn’t see coming, while the world around them quietly wonders if that’s actually true. When a new string of murders hits the news, these three women, who have arguably more firsthand knowledge of how killers operate than anyone else in the room, decide to figure it out themselves. In 1966. A time when women were very much expected to stay home and take care of the kids, not solve crimes.

That tension is where the book lives, and it works. Arnott does something that a lot of ensemble stories struggle with, which is giving each woman a genuinely distinct voice and set of motivations. Beverley is wound tight, trying to hold everything together through sheer force of will while raising two kids. Elsie is the bookish one fighting to be taken seriously in a newsroom full of men who would rather she made coffee. Margot is all polish and deflection, keeping up appearances because the alternative is letting people see how badly everything cracked. They feel like three different people with three different problems, not just variations of the same character in different outfits. That’s harder to pull off than it sounds, and it’s what makes this book enjoyable to read even when the mystery itself isn’t surprising you.

Speaking of the mystery, I had a pretty good idea who the culprit was earlier than the book probably intended. If you read a lot of these types of books, you might too. But here’s the thing about a well-constructed thriller: knowing where you’re going doesn’t ruin the trip if the company is good. Watching these three women navigate a world that underestimates them while also carrying the specific weight of being married to men who turned out to be monsters is genuinely interesting, and Arnott handles that complicated emotional territory without being heavy-handed about it.

The 1960s setting also really works. The period descriptions are very detailed, and placing this story in a moment when women had very few options and even fewer people willing to take them seriously adds a layer of stakes that a contemporary setting wouldn’t have. These women aren’t just solving a murder. They’re doing it while being told, in a hundred different ways, that they shouldn’t even be in the room.

If you like ensemble mysteries, historical settings, and books that center the inner lives of women navigating genuinely difficult circumstances, this one is worth picking up. It’s a solid, enjoyable read with characters that stick with you. The reveal didn’t surprise me, but it didn’t need to. I still enjoyed it.
