The synopsis for The Rule of Three reads: “How do you solve your own murder before it happens? Convinced that a mysterious urban myth called the rule of three is real, three women must find a way to break the curse or be doomed to die like those who came before them. But when you’re not sure if what you think is happening is even the truth, how do you know if you are actually in danger? And if you don’t know, how will you be able to protect yourself? Amy. Ila. Zoe. If death comes in threes, who will survive and who will solve the rule of three?”
Armstrong said: “With the creepiness of The Chalk Man and the paranoia of "The Blair Witch Project" The Rule of Three is an unsettling and propulsive read that I couldn’t put down. I’m delighted to be publishing the first standalone by Sam Ripley and, with one of the best first lines I’ve read, I am very excited to get this page-turner into peoples’ hands so they can enjoy the same sleepless night that I had when I first read it!”
Ripley said: “I’m absolutely thrilled to be published by Katherine Armstrong and the wonderful people at Simon & Schuster, who have been incredibly passionate and supportive since day one. The Rule of Three is a story that’s been living inside my imagination for several years now and so it is a dream come true to know it will soon see the light of day.”
Wills said: “The Rule of Three is an exceptionally addictive thriller that grips you from the first page and won’t let go. I found myself looking over my shoulder as I caught my breath. It is terrifyingly good.”
