Thanks to Headline and NetGalley for my advanced reader copy of this book.

True crime is my 'thing' so I was thrilled to be accepted for an eARC of this thriller. In A Serial Killer's Guide to Marriage, Haze and Fox are a married couple with baby Bibi – yes really – bonding them in suburban England beyond their initial interest-in-common: murder.

Through fun, witty dialogue, even funnier internal monologues from each main character, and a switching POV, this book becomes a page-turning mystery-thriller with a wild ending. I thought this would be a serious, dark book, but I'm glad that it was a racing mystery-thriller with humour, wonderful characters, style and adrenaline. The author brilliantly weaves in social commentary of what is morally right, and this was a great palate cleansing read. It has Mr and Mrs Smith vibes and definitely feels cinematic and compulsive in many ways.
