“Gripping and full of tension, with twist after unexpected twist. You won’t just read The Murder Rule, you’ll devour it.”
– Karin Slaughter, New York Times bestselling author of Pieces of Her

“The Murder Rule is tense and fascinating, dripping with the sort of suspense and intrigue we've come to depend on from Dervla McTiernan” Christian White, author of The Nowhere Child

“Deceptive and devious, this twisted and turned in exactly the way I hoped it would, resulting in an ultimately satisfying conclusion. A fantastic read.”
―Sam Holland, author of The Echo Man

“The Murder Rule is utterly absorbing, entertaining and intriguing.”
―Liz Nugent, author of Lying In Wait

“The Murder Rule has nailed something fundamentally true about being human; that none of us are quite who we pretend to be and that being the hero in your own story doesn’t stop you from being the villain in someone else’s. Grabs you from the first page and refuses to let go. Brilliant.”
―Gabriel Bergmoser, author of The Hunted and The Inheritance
