Pig Island

Journalist Joe Oakes makes a living exposing supernatural hoaxes, but when he visits a secretive religious community on a remote Scottish island, everything he thought he knew is overturned. 

Following the trail of a strange creature caught briefly on film, so deformed it can hardly be human, Oakes crosses a border of electrical fencing, toxin-filled oil drums, and pig skulls to infiltrate the territory of the groups’ isolated founder, Malachi Dove.

Their confrontation, and its violent aftermath, is so catastrophic that it forces Oakes to question the nature of evil—and whether he might be responsible for the heinous crime about to unfold...

Hanging Hill

On a picture-perfect morning in Bath, England, a teenage girl’s body is found on the towpath of a canal. Police detective Zoe Benedict is convinced the department head should look beyond the usual domestic motives to solve the brutal murder case. But no one wants to hear any far-fetched ideas from the department’s black sheep.

Meanwhile, Zoe’s sister, Sally, has started working as a housekeeper for a wealthy entrepreneur whose eccentricities are beginning to seem increasingly repugnant, and possibly dangerous. As Zoe digs into the case and Sally’s suspicions grow, all signs point to one conclusion: There’s something very wrong at the house on Hanging Hill.

Nine feet under water, police diver Flea Marley closes her gloved fingers around a human hand. The fact that there’s no body attached is disturbing enough—until the discovery of the matching appendage a day later. Both hands have been freshly amputated, and there are indications that the victim was still alive when they were removed.

Newly seconded to the Major Crime Investigation Unit in Bristol, DI Jack Caffery soon establishes that the hands belong to a young man who has recently disappeared. As Caffery and Marley search for the rest of the victim—and for his abductor—they journey into the darkest recesses of Bristol’s underworld, where drug addiction is rife, street kids sell themselves for a hit, and a disturbing occult ritual may be making an unexpected appearance.

When the decomposing body of a young woman is found, the wounds on her wrists suggest an open-and-shut case of suicide. But Jack Caffery is not so sure.

Other apparent suicides are cropping up, and they all have a connection to Elf’s Grotto, a nearly bottomless network of flooded quarries just outside the city. Caffery begins to suspect a shadowy and sinister predator, someone—or something—that can disappear into darkness and slip into houses unseen.

Working alongside Caffery is rough-and-tough police diver Flea Marley, but while pursuing her investigation, she stumbles upon something far too close to home that no one—not even Caffery—can help her face.

Jack Caffery’s new case seems like a routine carjacking until he realizes the sickening truth: The thief wasn’t after the car, but the eleven-year-old girl in the back seat. And she’s not the only young girl who’s been taken.

Meanwhile, police diver Sgt. Flea Marley is pursuing her own theory of the case, and what she finds in an abandoned, half-submerged tunnel could put her in grave danger. The carjacker is always one step ahead of the Major Crime Investigation Unit, and as the chances for the victims’ survival grow slimmer, Caffery and Marley race to fit the pieces together.

The Beechway High Secure Unit in Bristol, England, has a storied past—first as a nineteenth-century workhouse, then a poorhouse for the homeless, and now as a psychiatric hospital. With that troubled history come superstitions like the Maude, believed to be the ghost of a sadistic workhouse matron.

But while some of the patients and staff think the Maude is behind a series of unexplained episodes of self-harm amongst the ward’s patients, nursing coordinator AJ LeGrande thinks they might be the work of an all too human horror—a homicidal patient who was released back into the public in error.

Calling on Det. Jack Caffery, LeGrande hopes his investigation will reveal what’s truly been going on inside and outside the hospital’s walls. But what Caffery discovers about former patient Isaac Handel is beyond anyone’s imagining.

Wolf kicks off when a vagrant—the Walking Man, an enigmatic, recurring character in Hayder’s fiction—finds a dog wandering alone with a scrap of paper with the words “HELP US” attached to its collar. He’s sure it’s a desperate plea from someone in trouble and calls on Det. Inspector Jack Caffery to investigate.

Caffery is reluctant to get involved—until the Walking Man promises to exchange new information regarding the childhood disappearance of Caffery’s brother. Caffery has no idea who or what he is searching for, but one thing he is sure of: it’s a race against time.

Meanwhile, the Anchor-Ferrers, a wealthy local family, are fighting for their lives, held hostage in their remote home ten miles away. As their ordeal becomes increasingly bizarre and humiliating, the family begins to wonder: Is this really a random crime?
