They say I’m a murderer.

Six years ago, Kate Reynolds was found holding the body of her best friend; covered in blood, and clutching the knife that killed her.

I plead guilty.

Kate has been in prison ever since, but now her sentence is up. She is being released.

But the truth is, I didn’t do it.

There’s only one person who can help: Private Investigator Madison Attalee, the first officer on the scene all those years ago.

But there’s someone out there who doesn’t want Kate digging up the past. Someone who is willing to keep the truth buried at any cost.

Robert Galbraith meets Susie Steiner in this gripping debut from Niki Mackay.

Reviews

Had me hooked within two pages, it has every bit as much appeal as some of the bestsellers of the last few years, like Girl on the Train.
Robert Scragg, author of What Falls Between the Cracks
An absolutely gripping thriller founded on the horror of familial abuse and a great, flawed, female PI. There will be more Madison Attalee, I hope.
Dame Jenni Murray
Tough and uncompromising, I, Witness had me totally gripped. I'm looking forward to hearing more from PI Madison Attalee.
Alex Lake, author of Killing Kate, After Anna and Copy Cat
Cracking thriller and a great female protagonist. Swearing, smoking, rock-music loving (and not neurotic or passive!) My kind of woman.
C.J. Tudor, author of The Chalk Man
Cutting-edge gripping.
Sam King, author of The Choice
I couldn't put I,Witness down. A hugely accomplished novel with a dark, sad story at its heart - the characters are so well drawn that I felt every twist along with them as Mackay expertly manipulates the reader. With a wonderful, chain-smoking and perfume-spraying private detective driving the narrative, this is a 2018 must-read.
Phoebe Morgan, author of The Doll House
Totally engaging, fast-paced and edgy ... completely captivating. I, Witness kept me guessing till the very end. Pick this book up if you're after a page-turner with attitude.
Elle Croft, author of The Guilty Wife
I was swept away by this punchy, pacy thriller with its sharp characterisation and confident plotting. I devoured it in a single day. I particularly loved Madison's fabulously chain-smoking, hyper-feminine sharpness. There were so many things done well here - the presentation of domestic abuse, dysfunctional families, the uneven dynamic of female friendships that border on bullying - so much to enjoy. So looking forward to the next one.
Helen Callaghan, author of Dear Amy
A humdinger of a thriller debut ... a maze of lies, deceit and danger.
Evening Telegraph
With a fantastic main character in the troubled PI Madison Attallee (hopefully we'll be seeing more of her), a slick plot and the clever device of switching viewpoints from Madison to Kate to her sister-in-law Claudia and even Naomi's mum, Anthea, author Niki MacKay pull us in and keeps us guessing right up to the end of this pacy murder-mystery.
My Weekly
Niki Mackay's debut novel is a grippy, gulp-it-down crime thriller, deliciously full of twists and switchback revelations.
Living Magazine
As addictive as Killing Eve. You Will not want to put it down.
The Lady
Mackay builds tension to a fever pitch and throws in more twists than a corkscrew. Readers will look forward to Madison's next case.
