My kind of woman.' C.J. Tudor, Sunday Times bestselling author of The Chalk Man '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 Sunday Times bestseller Dear Amy '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 '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 apage-turner with attitude.' Elle Croft, author of The Guilty Wife 'Cutting-edgegripping.' Sam King, author of The Choice '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.'

Maybe they can help each other, and Ali won't feel so alone anymore. Then their due date comes and goes, and Ali hears nothing for weeks.
