About this listen

 Two former serial killers trying to keep their past buried realize that old habits die hard in this “wildly original, razor-sharp thriller” (Chris Whitaker, New York Times bestselling author of All the Colors of the Dark).

“An invaluable manual that I return to again and again.”―Hugh Grant

I wasn't smashing the patriarchy; I was killing it. Literally.

Hazel and Fox are an ordinary married couple with a baby. Except for one small thing: they're murderers. Well, they used to be. They had it all. An enviable London lifestyle, five-star travels, and plenty of bad men to rid from the world. Then Hazel got pregnant.

Now, they’re just another mom-and-dad-and-baby. They gave up vigilante justice for life in the suburbs: arranged play dates instead of body disposals, diapers over daggers, mommy conversations instead of the sweet seduction right before a kill. Hazel finds her new life terribly dull. And the more she forces herself to play her monotonous, predictable role, the more she begins to feel that murderous itch again.

Meanwhile, Fox has really taken to being a father. Always the planner, he loves being five steps ahead of everyone and knowing exactly what’s coming around the bend. Plus, if anyone can understand Hazel needing one more kill, it’s Fox. But then Hazel kills someone without telling Fox. And when police show up at their door, Hazel realizes it will take everything she has to keep her family together.

“An invaluable manual that I return to again and again.”—Hugh Grant

“Sexy, stylish, thrilling, and funny . . . Asia Mackay rips up the rulebook in this wildly original, razor-sharp tale of marriage and murder, mundanity and mayhem. I loved it.”—Chris Whitaker, New York Times bestselling author of All the Colors of the Dark

“Certain to be your sassy, twisted must-read of 2025.”—Janice Hallett, bestselling author of The Appeal

“Murder has never been so funny. If you liked Mr. & Mrs. Smith, you’ll love this original and darkly funny thriller.”—Clare Mackintosh, New York Times bestselling author of Hostage

“A killer idea! This is a laugh-out-loud page-turner that has insightful things to say about modern motherhood and marriage. A dark, twisted riot—I loved it from cover to cover!”—Ellery Lloyd, New York Times bestselling author of The Club

“Whip-smart and laugh-out-loud funny . . . I loved every page of this slick, witty thriller.”—Andrea Mara, author of Someone in the Attic

“I absolutely gobbled up this darkly funny and clever thriller about one of the most dysfunctional marriages to ever make it onto the page. Loved it.”—Katy Brent, bestselling author of How to Kill Men and Get Away with It

“So razor sharp, it had me reaching for the plasters. . . . A fresh and original voice in a genre we’re all fascinated with.”—John Marrs, bestselling author of What Lies Between Us

“A Serial Killer’s Guide to Marriage had me from page one. It was enthralling, exciting, and so totally badass. Mackay’s writing is so compelling and engrossing, and she writes characters that continue to live rent free in your head.”—Lucy Vine, author of Seven Exes

“Wildly entertaining . . . Mackay brilliantly exaggerates the stifling aspects of parenthood through the eyes of her charismatic killers, wringing both laughs and pathos from her deliciously outlandish premise. This is sensational.”―Publishers Weekly, starred review

“A dark comedy indeed . . . As a metaphor for modern family life, it’s entertainingly astute. Fans of Mr. and Mrs. Smith, this one’s for you.”—Kirkus Reviews

If you love thriller books, but want to switch things up with something a bit lighter, but not a total rom-com, this is your book. I loved it so much. Wish I could watch a series on these characters. It was a very easy listen. Loved the naratar. I am now eagerly downloading more of Asia's books. Surprisingly, with having more than 300 thriller, suspense, mystery, young adult, rom-com books in my library, I think this is the first I have favorited.

the best light, dark book

Checking to see if the rainbows and fluffy bunnies… This was a fun listen as I cooked dinner every night. Relatable due to just celebrating 10 years of marriage, 13 years together, except for the being serial killers part (that I know of…)

It was all worth it

I loved the tone of the book. Though at some point I was afraid it would lean too much on the “bored housewife” side and make Haze unlikeable but fortunately it didn’t happen. I loved the performance especially Haze’s. It reminded of Fleabag.

Pleasantly surprised
