The Organization has dispatched Ishmael and his partner Penny to Coronach House on the shores of Loch Ness, where the secretive but highly influential Baphamet Group are holding their annual meeting. The Organization believes an imposter has infiltrated the Group, and they have instructed Ishmael to root him - or her - out. It's not Ishmael's only mission. The first agent sent by the Organization has been found dead in her room, murdered in a horribly gruesome manner. Ishmael must also discover who killed Jennifer Rifkin, his fellow agent - and why. 

A rogue agent has come in from the cold and wants to spill his secrets. The Organization wants Ishmael to find out if Frank Parker is who he says he is, what he really knows, and why he has emerged from the shadows after all this time. Ishmael heads to Ringstone Lodge in Yorkshire, where Parker is being held to find that an atmosphere of fear and suspicion prevails. As he and his fellow residents are menaced by a series of alarming and inexplicable incidents, Ishmael sets out to prove that it's human trickery rather than any supernatural being behind the seemingly ghostly goings-on.

Ishmael Jones is someone who can't afford to be noticed, someone who lives under the radar, who drives on the dark side of the road. He's employed to search out secrets, investigate mysteries and shine a light in dark places. Invited by his employer, the enigmatic Colonel, to join him and his family for Christmas, Ishmael arrives at the grand but isolated Belcourt Manor in the midst of a blizzard to find that the Colonel has mysteriously disappeared. As he questions his fellow guests, Ishmael concludes that at least one of them - not least Ishmael himself - is harboring a dangerous secret.

Ishmael Jones and his partner Penny are attending the re-opening of Tyrone’s Castle, an ancient Cornish inn originally built by smugglers. Over dinner that night, the guests entertain one another with ghost stories inspired by local legends and superstitions. But it would appear that the curse of Tyrone’s Castle has struck for real when one of their number disappears into thin air. And then another....

Ishmael Jones and his partner Penny have been despatched to assist a group of scientists who are investigating a mysterious black hole which has appeared on a Somerset hillside. Could it really be a doorway to another dimension, an opening into another world? When one of the scientists disappears into the hole - with fatal consequences - Ishmael must prove whether it was an accident - or murder. But with no clues, no witnesses, and no apparent motive, he has little to go on. Is there an alien predator at large, or is an all-too-human killer responsible?
