By Andrew Pyper

“The Demonologist is that rare thing – a novel that is both genuinely terrifying and erudite.  The research is excellent and lightly worn, the pace and cleverness of the plot thrilling, one of the most exciting works of fiction I’ve read for some time.”
-Kate Mosse, author of Labyrinth, Sepulchre and Citadel

“It’s impossible to ignore the devils and demons who have a tangible presence in this story, but the novel’s deeper pleasure comes from the analysis Ullman applies to these horrors. ‘Fear — of death, of loss, of being left behind — is the genesis of belief in the supernatural,’ he explains, which makes horror stories more like ‘the history of man’s efforts to make sense of pain, of loss, of mystery.’ So bring on the devils and make way for Milton.”
New York Times Book Review


Pyper_The DemonologistProfessor David Ullman is among the world’s leading authorities on Christian religion and myth. Not that he’s a believer. He sees what he teaches as nothing more than entrenched fiction – the “things that go bump in the mind.” It’s why when he’s offered a trip to Venice to be a consultant on a case study based on his expertise as a “demonologist” he accepts, seeing it as a free vacation for his teenage daughter and himself. But what he witnesses in an attic room at an address amidst the decadent splendour of the old city will change what he believes forever. Terrified, David races back to his hotel. But now he has the unshakable feeling that he is no longer alone. And that the voice that passes from his daughter’s lips before she jumps from the hotel’s roof belongs to a being he has long studied, but until now never thought could ever be real… Deeply haunting and utterly compelling, The Demonologist is a powerfully moving tale of darkness and demons from the new master of modern horror, Andrew Pyper.

“A smart, thrilling, utterly unnerving novel. Pyper’s gift is that he deeply respects his readers, yet still insists on reducing them to quivering children. I like that in a writer.”
-Gillian Flynn, #1 New York Times bestselling author of Gone Girl

“Pyper’s novel might be properly categorized not as suspense, but as horror, a genre that has proven again and again–from Poe to James to King to Cronin–that it can marry plot with a prose that reaches a higher literary register. With The Demonologist, Pyper has won himself a place on that list. Despite its lovely prose and thoughtful execution, we offer a word of caution before you dive headfirst into Pyper’s latest: don’t plan on getting a good night’s sleep. Between your desperate attempt to finish it in one sitting and the novel’s abundance of absolutely frightening passages, you’ll be searching for sleep as desperately as Pyper’s hero searches for answers. And it will be just as difficult to find.”
Rogue Reader 

“Plenty of books claim to be scary, but this is genuinely terrifying, don’t-read-late-at-night stuff. Thrilling, compelling and beautifully written, The Demonologist makes Rosemary’s Baby feel like a walk in the park.”
-SJ Watson, author of Before I Go To Sleep

“Andrew Pyper’s The Demonologist is a smart psychological thriller served up straight with a twist of Milton. Part road trip, part family tragedy that touches on the nature of good and evil, it unfolds like a classical descent into hell, only played out against Interstates and cheap motels with vivid demons at every turn. Carefully crafted, claustrophobic, and deeply deeply creepy.”
-Simon Toyne, author of Sanctus

“Richly crafted, deliriously scary and compulsively page-turning from beginning to end. Imagine The Exorcist and The Da Vinci Code as penned by Daphne du Maurier. Don’t miss this one!”
-Jeffery Deaver, New York Times bestselling author  

“Andrew Pyper is a rare breed. Reading The Demonologist is like running through a house on fire – you’ve got to get through; nothing will stop you. And when you’re out, brokenhearted and bewildered, you’re left wondering if what happened was real. That’s Pyper’s brilliance: he does it so well you never see the fiction.”
-Sarah Langan, author of The Missing

“Andrew Pyper’s satisfying prose propels a narrative sure to please readers with or without a dog-eared copy of Milton’s Paradise Lost on their shelves. If you’re looking for smart horror that chills without resorting to Grand Guignol, give The Demonologist a look.”
-Christopher Buehlman, author of the World Fantasy Award-nominated Those Across the River

“Smart and astonishing, Andrew Pyper has created a recurring nightmare for adults. The Demonologist holds a mirror to the reader and reveals the places where our deepest darkness lurks. Like Milton’s Paradise Lost, this is the story of the human condition, the fall, and the way back. I slept with the light on for nights, too obsessed to stop reading and too terrified to dream.”
-Brunonia Barry, New York Times and International Best Selling Author of The Lace Reader and The Map of True Places  

“The evil of Milton’s pandemonium comes to life . . . Pyper’s novel takes on “things that go bump in the brain” and delivers a stirring entry in the supernatural thriller genre.”

 “Pyper is an intelligent writer, steeped in Miltonian symbolism, gifted with language . . . This artful literary exploration of evil’s manifestation makes for a sophisticated horror tale.”

“A mesmerizing and melancholy narrative voice lends chilling credibility to this exceptional supernatural thriller.”
Publishers Weekly (starred review)

“A complex novel about loss, anger, faith, grief, love and forgiveness…[The Demonologist] will frighten you out of your shoes.”
-Toronto Star

 “The Demonologist reads like a ready-made screenplay, a fast-paced Exorcist-meets-Da Vinci Code where the actual horror happens off-screen, in the mind. Which, as Pyper surely knows from Milton, is where evil truly dwells.”
Maclean’s Magazine

“Pyper’s a star because he writes so spectacularly. The entire story is drenched in dread, and his most terrifying scenes are so vivid, you’d best not be reading the book just before hitting the sack.”

“Ah, I loved this. Pyper has a way with words, and in The Demonologist he has created a beautiful and truly disturbing work of literary horror…Highly recommended.”
-Devourer of Books blog

“Part horror, part thriller, all page-turner . . . The Demonologist has all the twisting excitement of a Dan Brown novel, and all the lurid, gory violence of a Stieg Larsson.”
The Globe & Mail

“This book is going to be big, and it’s going to be popular, and it absolutely deserves to be both of these things. You should buy it, and read it, and let it scare you stupid.”
National Post

“A chilling novel for readers who like their horror presented with literary flair.”
-Fort Worth Star-Telegram (US)

“In the sly, creepy and often-horrific The Demonologist, Andrew Pyper knows how to get under the skin of even the most rational reader.”
The Columbus Dispatch (US)

“Proper creepy.”
Chatelaine Magazine

“Taut, intelligent and utterly gripping…[The Demonologist] is a fascinating exploration of the darkest corners of the human psyche.”
Raven Crime Reads

“* * * * [Four Stars]…Intense and satisfying.”
-BookBanter Blog

 “The plot rarely flags and remains difficult to predict, twisting elegantly rather than through clear contrivances, and the Miltonic and biblical echoes add an extra layer to what is, at its heart, a dissection of depression and an argument for hope.”
Winnipeg Free Press

“[U]napologetically pulpy…”
Toronto Life

“There is no clutter in Pyper’s writing. He gets the story rolling through calm and learned prose that chills to the bone…Pyper’s novel is enthralling in its subdued intensity. There are no pyrotechnics à la William Peter Blatty’s The Exorcist — more a slow burn to a pulse-pounding end.”
Montreal Gazette

“With THE DEMONOLOGIST, Andrew Pyper has created a truly blood-curdling work that will have readers looking over their shoulders and on edge from beginning to end. Whereas other classics in the genre have focused on battling evil, this novel seeks to understand the very nature of evil from its origins. The fact that he is able to breathe life into the book’s plausibility creates an unsettling feeling and completely satisfying horror read without ever becoming clichéd in the process.”

“Recommended for teens who enjoy intelligent, literary puzzles…Genuinely scary and unexpected.”
School Library Journal

“A stunningly crafted, intelligent and moving horror story… There is an elegance to the storytelling and a command of what evil may mean, that lingers with you long after the end. No surprise that it is development as a major film.”
Daily Mail (UK)

“A chilling exploration of how we all have to do battle with our own demons.”
Mail on Sunday (UK)

“The pace heats up in the first chapter and stays to the climax. This is storytelling that transcends the boundaries of genre: mystery (a vanished child), thriller (evil), a page-turner. It’s beautifully written, with layer upon layer of fear, redemption and deep feelings rarely expressed in a fiction. The Demonologist should not be missed.”
Hamilton Spectator

“A horror-thriller that grips the reader in a tale that haunts, questions and terrifies all under the wrappings of highly literate prose.”
Shots Magazine (UK)
