Murder in the dark
(Book)

"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."--Publisher's description.
