The sudden appearance of a sinister black hole in the English countryside leads to a baffling murder investigation for Ishmael Jones.

"The past is England's dreaming, and not all of it sleeps soundly ..."

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? Only one thing is certain: if Ishmael does not uncover the truth in time, more deaths will follow.
